Reducing image size with Preview?

I notice that Preview's "adjust size" option can considerably reduce the size of some images i got from internet. For instance, with a 366 KB JPEG image, after clicking on adjust size, there would be a line at the bottom of the window that says: 101 KB (was 366 KB). And i know this new smaller sized image has the same quality as the original because when i compare both images at maximum zoom, i see no difference in the size, color or position of the pixels. So, does anyone know how this size reduction method can be applied simultaneously to many images or to an entire folder? Or do you know any software (preferably free) that does something similar without quality loss?
Thanks in advance

Then change the subsampling rate or turn it off in the PDF Optimizer. But realize that in doing so you trade the quality for a larger size.

When reducing image size with acrobat using subsampling it does a poor job.

this seems to occur on all Images and is really noticeable on images below 20 percent.

I am on a Windows 7 OS attempting to reduce pdf size with my Adobe Acrobat Standard XI & Pro. The application keeps timing out and at the Subsetting embedded fonts portion and the application gives "Adobe Acrobat has stopped working" and then closes. The document is 275 pages. Is there something I can do to stop this?

Hi Ricci,
Since when are you facing this issue? Did you tried system restore to a date before this problem occured.
Does acrobat stop working when you open this specific pdf file or with any pdf file that you open?

Reducing image size without reducing quality

Hello all.
I'm trying to learn if there is a way to reduce the size of an image in Pages without reducing the quality. It seems that when I use the built-in command from the file menu or by control-clicking on an image, the images go soft after the reduction. There has to be a way to keep the photos sharp without having them take up so much space. Any tips out there?

Best is to take the original images into Preview and:
1 Crop them to the view in Pages
2. Decide what resolution you want for the final size in Pages:
300dpi for good quality printing
150 dpi for good quality screen appearance
72 dpi for bare minimum screen appearance
3. If they are color photo like images, save them as .jpeg with as much quality loss as you you can tolerate
4. If they are flat areas of color or black and white save them as compressed .tiffs
After cropping and compression bring them back into Pages and use no compression there at all.

How do I reduce file size in Preview?

how do I reduce size in Preview? Tools > Adjust Size is greyed out. I have a scan of receipts at 300 dpi that's 5.3 MB. I want to reduce for e mail.

I did go back and saved to .jpg and got an option to determine the quality and settled for 225 KB image. That works and it looks fine.
Unfortunately, though I clicked correct answer on your post - it looks like its giving me credit. I tried to undo, but I can't.

How to reduce image size on account of disk space shortage?

I import images from my camera to iPhoto on my MacBook. I want to reduce their size on import because hard disk space on MacBook is limited.
Is there any smart way how to perform it? I have not found any presets on Import dialog to reduce size.

If the photos are important then get an external FW hard drive and move the library to it and operate from there. Delete the library from your MacBook.
Next create a new library on the MB and copy only the photos that you have an immediate need for from the external library with the paid version of iPhoto Library Manager. It will copy the metadata, keywords, faces, places, and edited versions between libraries. You will a lean, mean travelin' library for the MB.
You you add photos to the library on the MB while you're on the road you can copy them to the main library in the same manner with iPLM when you get back home.

How to Reduce Image Size and show upload Progress Bar

i need to capture an image from the camera and send it to the server. however to reduce the amount of data transmitted i want to shrink the image and lower its resolution.
I have code that currently does the following :
UIImage *testImage = [UIImage imageNamed:@"image1.png"]; // this would come from image picker
NSData * imageData = UIImagePNGRepresentation(testImage);
// skipped code that showed URL string setup
NSString *postLength = [NSString stringWithFormat:@"%d", [imageData length]];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];
[request setHTTPBody:imageData];
NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:request delegate:self];
1. need some way to shrink the image size to reduce data traffic
2. need some way to indicate a progress bar as data is being transfered to the server

1. The size is visible in the metadata panel, set the dropdown to EXIF. In addition, in the Grid, with Ctrl-J, you can set the options so that you will see the cropped size in the rectangle surrounding the photo.
2. You cannot, in one action, upload to multiple galleries. Each upload is its own action. I don't know if there is a plug-in to let you upload from LR to 500px in one action; clearly there are plug-ins for Flickr and Smugmug and several others. There should be no need to re-import. Normally, the plug-ins I mentioned will take a TIFF, resize it according to your directions, convert to JPG and upload.

Reduce image size

Hello,
I have a question about reducing the size of an image.
What i want is to load an image.. resize it and then save it
into a blob(sqlite air db)
In php you say imagecopyresampled and you can save a smaller
image.
How to do this in flex?
What i have is an function witch resizes the given image, but
i doubt the image is really reduced in size..(from 900 to 100k)
code:
package
import flash.display.Bitmap;
public class imageresize extends Bitmap
//globals
private var bmp:Bitmap;
private var true_width:Number;
private var true_height:Number;
private var maxx:Number;
private var maxy:Number;
private var resize:Boolean;
public function
resizeImage(b:Bitmap,h:Number,w:Number):Bitmap
this.bmp=b;
this.maxx=w;
this.maxy=h;
this.true_width = bmp.width;
this.true_height = bmp.height;
//this.true_width2 = imagesx($image);
//this.true_height2 = imagesy($image);
this.resize=false;
if (true_width>maxx) resize=true;
if (true_height>maxy) resize=true;
if (resize==true)
var width:Number=maxx;
var height:Number = (width / true_width) * true_height;
true_width=width;
true_height=height;
if (true_height>maxy)
height=maxy;
width = (height/true_height)*true_width;
else
width=true_width;
height=true_height;
else
width=true_width;
height=true_height;
width=Math.ceil(width);
height=Math.ceil(height);
// this is used extra in php to get a smaller image
//$dest_img = imagecreatetruecolor($width, $height);
//imagecopyresampled(
// $dest_img, $image,
// 0, 0, 0, 0,
// $width, $height, $true_width2, $true_height2); // resize
the image
//return $dest_img;
bmp.height=height;
bmp.width=width;
return bmp;
please some help here,sorry for the way i put the code here..
i couldn't find the attach code button..
or did i have to use [attach code]? maybe handy to change the
string attach code into a link..
Greets, jacob

perhaps another nice thing is to encode it to base64 so it
can be saved into the sqlite database.
I found my one solution by encoding it to a base64 string and
store it into the db.
Here a link to the topic with the solution.

Reduce image size in pages by cropping ??

Hello,
I created a pages document with a lot of masked images in it. the resulting pdf file is massive. As described in the Pages manual, I tried the reduce the image file size (format menu) and the document file size (file menu). But instead of reducing the size by deleting the the parts of the images that are covered by the mask (as written in the manual), it reduces the image resolution, which I don't want.
Question: How can I reduce the image file size by cropping and not by reducing the resolution.
I learnt a lot today in other forums on how to edit quartz filters, so I know how to manipulate resolution afterwards for pdf's for mail and print. Cropping images before inserting them into Pages I don't find a real option. Thank's for yor help.

I reported it to Apple via the feedback button. I also added a little wishlist for the next version.
I think if Pages would crop the excess parts of an image covered by a mask during the pdf export would solve the problem already because imho these not visible parts are often the reason for the massive pdf file sizes. The images are completely embedded and masked in pdf's.
Does anybody know a pdf tool that does that? I tried PDFshrink and PDFpen so far, but they both don't.
Would also be cool to have an Automator action that adjusts resolution via edited quartz filters and crops the invisible stuff off ...

Reduce image size ( un-enlarge )

I have a digital image of a house. I want to make a Christmas tree ornament that will have a picture of just the front door. The door in a 4x6 print is about 3x4. I want to reduce that to about 2x3. I am only able to print on 4x6 paper, so I want to reduce the image size then print a 4x6 which would orobably have a large white border.
How can I do this?

Cliff
1. Open picture file
2. Access rectangular marquee tool. In the options bar, select mode:fixed size, enter w=2", h=3". Position the box with the "marching ants" to include the door.
3. Go to Image>crop
4. Go to Edit>copy. This puts the door on the clipboard.
5. Open a new blank file, background white, 4X6", the size of your paper stock, and set resolution the same as that of the picture. Note that for printing it is desirable to have a resolution of 240-300px/in
6. Go to Edit>paste
The parameters in step #2 can be refined to reflect the actual door size.
If you want to have a background other than white, you certainly can to this. In step #5, you can select the foreground color of your choice. Just set the foreground color chip (lower left) to the desired color.
It is also possible to paste the selection on to a texture background, etc.
HTH. Let us know how you make out.

Camera raw reducing image size

All of a sudden Camera Raw is automatically reducing my image sizes. I cannot figure out why. The images were shot with a Nikon 5100 if that has any value.
The original jpg size is 15MB (jpg) and have a NEF extension.
I've tried opening the image in Photoshop and then going through Bridge to Camera Raw, and opening the image through Bridge to Photoshop and the image gets reduced from 16 inches to 5 inches keeping 300 dpi.
Thanks in advance.!

The only important “image size” is pixel dimensions.
JPGs have a JPG extension. An NEF extension means it’s a raw file.
Things that affect DPI/PPI and pixel dimensions are in the workflow options link at the bottom of the main ACR window, and only if you output the images to some other format in ACR.

Reducing image size in I photo 7

I am trying to reduce the size of images in iphoto. I tried to export, but the function is greyed out an inaccessible. I tried turning off any 3rd party plug in's as suggested on another post, but that didn't work.
the export function appears available from the top of the event menu, but when I click it, nothing happens. Help! How do I reduce file sizes?

gahpgirl:
Welcome to the Apple Discussions. When exporting select the format to jpg instead of Current or Original. Then you'll be able to set the quality level which will reduce the file size without affecting the picture size, i.e. pixel dimensions.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Reducing image size loses sharpness

BEFORE YOU LEAVE WITHOUT READING THIS WHOLE THING, YOU MAY BE ABLE TO HELP BY ANSWERING ONE SIMPLE QUESTION:
I have a background that has 8.5" x 11" external dimensions. In the project bin, I'm also showing a layer (with transparent edges) that I've resized to 1" x 1.5". When I double-click the background to put it on the screen, and then drag the layer onto the screen, why doesn't it look like a small picture on top of a big one? Instead, it's huge, and I have to drag it down to size with the move tool!
===========================================================================
And now, the entire story:
Running PSE9 under Mac OS X 10.6.8 Snow Leopard.
My project is a montage of stamp-sized images on a letter-size background, as in the attached -- commemorating the woman in the centerpiece. I've stumbled though this kind of effort before with great success. This time the small photos are coming out blurry, and it's because this time I've done one thing differently.
In prior efforts, I recall somehow reducing the outside dimensions of an open file to about 2" x 3" before editing and finally adding it as a layer to the big background (using Move Tool to size it to fit), although during editing I was working with a reasonably-sized image and not a stamp (probably using command +). The images in the final version were all sharp. On this effort, however, my aging brain did not help me remember how to do it the same way, and I ended up working with the original photo, and then when I added it as a layer, I reduced it using the move tool -- very clumsy in view of the fact that the edited layer's image seemed to be larger than the canvas I was building, and the final images were blurry.
I started reading Help on the subject of resizing, but that was way too much information for me to absorb before the end of the new year, and I'd like to finish the work in the next few days. (The attached photo IS the current project, and I whipped it out in a day, albeit blurry.) I'd appreciate it if someone could give me a brute-force step-by-step to do it the way I've done it successfully before.

The answer to your first question and the big one are very closely related. When you combine images, the resolution of the bottom (background) layer determines the resolution of the entire image. This means that if you have a low-res background (say, 72 ppi) and then you bring in high-res images (say, 300 ppi) the added content will be huge in comparison to the size of the overall image. When you scale it with the move tool you aren't doing yourself any favors if you make large changes that way.
The best way to approach this is to make sure that all your images are at about the same resolution before you start (image>resize>image size). Also, make sure your background is not at a low resolution or the end result will print badly no matter how much time you spend combining things.

E-mailing photos without reducing image size

I have tried using the image size box in the message window (set at actual size) but still a 4MB photo in my aperture library is reduced to 400kB when I attach it to an e-mail. I'v spent far too long on this. Would appreciate help. Cheers.

How are you getting from Aperture to Mail?
Using File>Email from Within Aperture? This will reduce the pixel dimensions of the image according to the export preset chosen in Aperture's preferences.
Dragging an image from the Aperture window into an email, or using the media browser? This will use the Preview file, and the pixel dimensions will be constrained by your Preview settings in Aperture, and will cause problems for people who aren't using Apple Mail because the image will be in Adobe98 not sRGB.
Another question - what is the original file format? Even if the pixel dimensions are the same, 4MB to 0.4MB difference could be due to going from a TIFF or PSD to a JPEG.

Reduce image size and print it out?

I scanned an image (coloring on a postcard). This size is too big to fit into a 'album' picture in MS Picture It! All I want to do is REDUCE the image and save it so that it will fit into the computer photo album I'm creating.
I've tried Image/Resize/Image Size and changed the sizing, but it still comes out the exact same size as the original. What am I doing wrong?

> I want to REDUCE the image, not enlarge it.
I understood that - what makes you think I didn't?
> It's 948x645 pixels. I just want the image about an inch (respectively) smaller
You can't think in terms of inches for screen images. You have to work in pixels and the actual size will depend upon the screen resolution on the machine being used to view the image.
I'd reduce the pixel size by about 80 to get the effect that you want. Use Image/Resize/Image Size and make sure that you have "Resample" checked.
