Reducing pixel size of saved photos

I'm very new to my iMac. I've saved several dozen photos in iPhoto and just tried to upload one of them to a boating website. It was apparently too 'big' in that it had too many pixels. My question: How do I copy a photo in a reduced pixel 'size' so I can upload it to a website with a pixel limit? Thx,
Tony

You would probably have to crop the photo to the correct ratio first
http://docs.info.apple.com/article.html?artnum=165597
After the photo is cropped, then you would follow the directions above to export it.
Put the length and height in pixels in the appropriate boxes and export to the desktop.
If you need more help then give more info on the exact size of the photo you need exported.

  • Help reducing pixel size on i photo.

    Hi
    Desperate for help. I need to rezize to 675x550 to upload to a website. I do my crop and then export.I enter the above values and proceed. However when I check the photo info in the library the size is 675x450. This happens all the time.How can I acheive 675x550
    Cheers Paul

    Paul:
    Welcome to the Apple Discussions. What you want to do is export the file to the desktop using the File->Export->File Export menu. In the export window select Format = JPEG and Size=Custom. There will be a sub window where you can put in the maximum pixel dimension for the photo and the other side will be resized accordingly while keeping the size ratio intact. Set the other options as needed and finish the export.

    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) 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 or later), 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 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. 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.
    Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

  • I have tried to use File - Export to reduce the size of my pics to send via email and all I get is a blank pic.  How do I reduce the size of the photo and still have the photo?

    I have tried to use File > Export to a folder on my Desk top to reduce the size of my photos and all I get is a blank, grey screen.  How do I reduce the size of my pics so I can email them?

    Where are you getting this screen?  In iPhoto after selecting the File ➙ Export menu option? If that's the case try this:
    1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/() Library/Preferences folder.
    2 - delete iPhoto's cache file, Cache.db, that is located in your Home()/Library/Caches/com.apple.iPhoto folder. 
    3 - launch iPhoto and try again.
    NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences..
    You can resize photos outside of iPhoto with 3rd party applications like Resize!.
    Click to view full size
    With it you can change both the pixel size and file size of the photo to the size that suits your needs.  For other such apps go to MacUpDate.com and search for "image resize" to get a list of potential candidates.

  • How do I find the pixel size of a photo?

    I have taken a photo or found one online.
    It's now on my ipad.
    How do I tell the pixel resoution of the photo via the ipad?
    I have two of the same photos on my device at the moment and want to delete one.  They may both be 2048/2048, but without emailing them or putting them in Dropbox, and viewing on my laptop, I don't see how to tell.

    Get the Actual Pixels App from the App Store. It's free and will tell you the pixel size of any photo you open.

  • How do I change the pixel size of my photos?

    Hello,
    Please give me step by step instructions on how to change the pixel size of my photos from the time I log in.
    Thank you.

    There are basically two ways.
    Image>Image Size... This will adjust the quality of the image, allowing you to adjust the pixel dimensions and keep the full image.
    In the tool bar on left side of screen 5th icon down looks like a sliding picture frame. That is the crop tool, that will adjust the pixel size of a document by removing a portion of the image, allowing you to get rid of portions of the image you do not want.
    There are some other ways to accomplish the above, but these are the basics that everyone needs to know. I recommend playing with these tools on a copy of an image, that way you won't be afraid of destroying an image.

  • How can I reduce the size of a photo proportionally.  With my old Mac mini I was able to place the pointer on the bottom right corner  hold the shift key until I achieved the desires size.

    How can I reduce the size of a photo PROPORTIONALLY?  With my old Macmini I was able to place the pointer on the bottom right corner of the picture, hold down the shift key and move the pointer to achieve the desired size.  

    You'll need to use a 3rd party editor like one of these:
    Some Image Editors That Support layers:
    Photoshop Elements 11 for Mac - $79
    Rainbow Painter - $30
    Imagerie - $38
    Acorn - $50
    Pixelmator - $60 
    Seashore - Free
    Portraits and Prints - Free
    GIMP for Mac - Free
    Xee 2.1 - free
    My personal preference would be for Photoshop Elements for Mac. Most of these will let you select and copy a head from one photo, paste it into another photo, resize and place where you need it.
    PSE has a specific feature just for that function.  I belive the Adobe site for PSE has a demo video of that feature.

  • Is there a way to reduce the pixel size of multiple photos in a slideshow?

    I have a Windows 7 computer and use Photoshop Elements 9 and Premiere Elements 9.  I recently completed a slideshow that contains about 360 photos, many or all of which exceed the maximum size of 1000 x 750 pixels.  Is there any way that I can easily reduce the pixel size of each of the photos?  If upgrading to the most recent versions of Photoshop Elements and Premiere Elements would help me accomplish this I would be willing to do this.  Thanks very much in advance for any advice or suggestions.

    You can batch process your images to re-size them in the editor using the menu:
    File >> Process Multiple Files
    Place your chosen photos in a separate folder and then choose a separate destination folder; so as not to overwrite the originals.

  • 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.

  • Why do my images and layered files 'shrink' in pixel size when 'saving as/saving for web'?

    I'm using CS3 and when I "Save As" or "Save For Web" to a format like .jpg for example, the resulting .jpg is reduced in size considerably.
    For example I was touching up a photograph that was 1300 x 700. I saved out the file for web to my desktop and emailed it to a friend. When my friend opened it, it had shrunk down to about 75% of the original 1300 x 700 size. I have the same problem when saving out layered .psd's, which lead me to believe it had something to do with my save settings. I've scoured the net for answers as well as gone through each setting, but have not been able to solve this problem.
    Thanks in advance for any assistance you can offer in solving this annoying problem!
    Jason

    Jeffrey, I checked the UI dialog and it's set to 'original'.
    Marian, this problem occurs whether I email the file or not.
    Thanks for the responses guys, but the problem continues. Any other thoughts? Remember this happens under both 'Save As' and 'Save for Web' actions.

  • How do I reduce MB size for jpg photos?

    How do I reduce the MB size for a group of photos I took. I want to save these reduced photos and send them to a client.

    IF you want to reduce just the file size and not necessarily the dimensional size...
    Create an action to "Save for Web", and run a batch using that action.
    I'll show it on a Mac but it's the same for Windows.
    1. Open one photo.
    2. In the Actions panel click the menu selector and choose "New Action.
    3. Name the action and click "Record".
    4. Press Alt+Ctrl+Shift+S to Save for Web (Alt+Cmd+Shift+S on Mac).
    5. Select a save destination and then close the file, selecting "Do Not Save" when you do so.
    6. Press the Stop button.
    7. Click File>Automate>Batch.
    8. Choose the parameters for the batch and click "OK"
    It'll reduce the file size of the photos you chose.

  • Reducing file size on multiple photos

    I up load my photos for prints. Most of my photos are 2+ mb in file size so when I am up loading a group of photos for prints it takes an hour or so at a time. Is there a way in Elements 4.o to reduce the file size of multiple photos simultaneously for up load without over writing the original image?
    I'm willing to save a copy of the images in the reduced file size that I could delete after up loading, but would love to find a way to reduce the file size on multiple images instead of "Save as" on each image.
    Any thought would be appreciated.

    Good evening
    Process multiple files (under File) should do what you want-you can select files from a folder, send them to a new folder (to save the originals), adjust size and quality. The pop up window is fairly straight forward, but post back if you have any questions.

  • HT3805 How can I adjust the pixel size of a photo

    I wish to upload pictures to a site and they have requested min size 40 x 40 max size 200 x 200  I assume this is pixel size but can find no way of doing this in Aperture.
    Surely this is a common enough request?

    Use the file export command (Shift-Command-E), adjust the size to whatever you want.
    You can make your own preset by pressing the + sign on the lower left corner.
    If you forget any of this, just use Apertures Help screen:

  • Reducing KB size of multiple photos

    This isn't really an iPhoto question, but if I have a file of photos that are all
    2.5KB each or whatever and I want to reduce them all by half, is there a way to do this other than photo by photo?

    Make a workflow with Automator?
    Many editors will do batch operations - Graphic Coverter is one that springs to mind.
