Converting PNG images to Jpeg

I am operating with iPhoto 6.0.6 and have a lot of recent wedding photos that were sent to me in PNG format. How do I convert these images to jpeg? I've found lots of shareware for conversion but nothing that will run on a mac.

Is there any reason to convert them? PNG is just as portable as JPEG.
You can export png from iPhoto and choose JPEG as the destination format using the File -> Export command.

Does Web Module size and convert RAW images to jpeg?

I have never used the Web module before. It looks pretty straightforward but I have one question:
What about images? Does Lightroom take the original RAW images from the library that I've chosen to go into the web site and 'pare the down' or re-size them to be appropriate size for the web site and I assume it would also convert them to jpegs in sizes needed for preview and for thumbnails?
I assume that when you start the 'machinery' for Lightroom to build the web site that it will put all of the images needed as copies from the originals into a proper folder that can be then uploaded to the web?
Thanks,
Ken
PS: if I choose a flash template, which are pretty nice, does it also include the flash module so that people can run the flash presentation on their computers?

It will convert all images to jpegs, resize ... however you set it up ... and yes, it is so straightforward as it seems to be .
It makes no sense to upload RAW files to the web for public use in the first place. Second, LR does not touch/change the RAW files. Therefore, how would it be able to integrate your dev settings when using RAW on export?
You can add the ftp target in LR and it will upload directly to your web server.
If you choose Flash-based, people need to have the Adobe Flash player installed on their computer. The Flash player itself is not part of the LR setup. Most of people already have it installed and who doesnt will be asked to install it.

Converting tiff images into jpeg

I would like to convert tiff images into jpegs with iphoto. I dont want to duplicate all my photos and then have to delete one by one!
How do I do this?

Welcome to the Apple Discussions. The short answer is that you cannot. You will have to export the files via the File->Export->File Export menu option, selecting jpeg as the format and checking the box to include the keywords and comments, and maximum size. Then import the jpgs and delete the tiffs.
You can get all of the tiff files together by doing a search for .tif. Then do a Select All (Command-A) and go to the export menu. Export all to a folder on the desktop. Import the new jpgs into iPhoto.
To get rid of the tiffs once the jpgs are imported do another search for the tifs and select all again. Then type Command+Delete. That moves the tiff photos to iPhoto's Trash bin. Then empty the bin.
If you have multiple files with the same file name you'll have to do some renaming before the export. You can batch rename them using the option Title to Date/Time or just date alone. I use the date taken as the file name as that gives me excellent chronological sorting and searching by filename for dates.
Do you Twango?
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. 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.

How to convert PNG image to Vertor Image to make font on Mac

Hi Mac People,
I like to create a set of font, and I have made them in a image editing tool, I have FontForge downloaded but decide to use it to convert instead direct design them inside.
So now I don't know how to convert the PNG image to vector image required by the FontForge, I read some post mentioned Ubuntu has utilities to convert, but I'm not sure OS X has that function too.
Could anyone let me know how to convert PNG so I can create my fonts?
If PNG can't, the software can export TIFF or jpeg or similar.
Please help me, I need make them this few day.
Thanks everyone for giving me a hand!

Problems converting PNG image to SVG with autotrace

Hi,
I am trying to convert a large number of color PNG images of hieroglyphs (produced after much effort) to SVG format, using "autotrace -background-color ffffff -output-format svg".
It seems that where there are closed paths with background color inside, autotrace produces an SVG image with the background area in black instead of transparency. (You can see the images at http://5b4az.chronos.org.uk/pkg/hieroglyph/A001.png and http://5b4az.chronos.org.uk/pkg/hieroglyph/A001.svg although the svg image is not rendered by Firefox). You may also download the tarballs with all the hieroglyphs of the Gardiner set if you are interested.
After all the effort that went into these images, I am stuck with being unable to convert raster images to vector graphics. I did try autotrace before I put in all this effort, but I didn't notice the problem because apparently I tried it on images with no enclosed background color.....
Any suggestions wellcome greatefully!

I know this is an old thread, but I did some new testing on some line art and want to post my results.
I started with a PNG, and converted it to PBM and PGM. I got much better quality doing this conversion with GIMP, as opposed to pngtopnm.
I traced both formats with autotrace and potrace, which I output to SVG.
Autotrace accepts PNG, so I did the trace with the original as well.
I got the highest quality with PGM and potrace. It also was the smallest file size.
a close second was PBM with potrace, slightly larger.
third was autotrace and the PBM, larger still.
Using the PGM with autotrace was unacceptable, and the file size was HUGE!
So if black/white is OK: Convert PNG to PGM with GIMP, then potrace
both the best quality, and smallest size SVG. This is assuming you started with anti-aliased black/white line-art, i guess the full greyscale PGM avoids the aliasing of PBM.
It seems autotrace is the way to go, if your forced to deal with multiple colors.
I suspect you will need to do many passes and really tweak those command options,
The PNG directly to autotrace was a complete disaster, but i suspect it would improve given enough time to configure command arguments.
However, even with those perfect options I would believe potrace yields a cleaner trace.

Converting raw images to jpegs using PSE 11

I have started to capture only RAW images from my Sony NEX 7 camera. However, I wish to be able to send JPEG images to my friends ( prior to RAW editing ). How do I convert/copy my RAW images to JPEGs using PSE 11?
Thanks
Derek

After you're done in camera raw (or in your case, without doing anything, but you'll just get the default conversion, because you MUST convert the files), click the Open button, then save in the format of your choice in the editor. JPEG is an 8 bit format so you will want to either set the raw converter's pulldown menu to 8 bits or you will need to go to Image>Mode> 8 bits/channel in the editor. If you're emailing, you can also use Save for Web to size them down if necesary.
If you use the organizer, you can just use file>export as new files and be sure to send the jpgs someplace easy to find.

Batch converting psd images into jpegs in pse 10 or 11?

I want to batch convert the above. I know i can convert one image at a time. If not can one recommend a batch conversion program which is safe to use and free from viri and malaware. Thanks!!

And when you are in the process multiple files menu what do you select from their to do the batch processing of the psd images to the jpeg images. I need a step by step here. Thanks!!

How to batch convert tiff images to jpeg in Pages document

I have a large (about 1Gig) Pages 5 Package document with hundreds of images, mostly in tiff format. Since the software became nearly unresponsive, I need to convert image files in jpeg (though I wonder why unresponsiveness in the Package mode). Reducing file size is not an option since it decreases resolution.
Is there a script, perhaps, that would convert all images in a Pages document to jpeg?

What version of Pages?
Not to my knowledge.
You may be able to create an AppleScript, a very long shot, but it will not use Pages to do the conversion and will take longer to do than simply correcting all the images and reimporting them.
Preview.app can convert from one format to another and there are Automator workflows that will convert image formats. You will lose some detail because jpegs are a lossey format whilst tiff is not. Have you looked at reserving the images as compressed tiff files?
How did you get into this position? You must have known the file would be huge with so many large images in it. Pages 5 is particularly bad, increasing file size exponentially.

Converting raw images into jpeg images

I am trying to build a small application that can help me to convert raw images (of one of my cam) into JPG image.
i have earched in google ans found many API ie, JRAWIO,JAI,mistral-0.9.6.809 and Imagero.. but i am not able to understand how to use them in my program..
JRAWIO is helping me to convert NEF and TIFF. though it has functionality fto use it for CR2 ans othr but i failed to use them..
plz help me out if possible with code(full if possible) and step by step description...

Hi,
we can not do the homework for you but we can help you out to the right direction.
1- Get the input stream from the image file ( source )
InputStream is = new BufferedInputStream(new FileInputStream(
"C:\\tmp\\sasha.jpg"));
2- Get your BufferedImage
BufferedImage buffImage = ImageIO.read(is);
3- look at the API docs for BufferedImage it contains the image data ( Raster)
4- I have not looked at the source code for the JRAWIO but I think it uses javax.imageio.* as an underlying transformation engine

How to convert AIPD Image to JPEG?

Hi everyone,
I am having problems with (what I thought to be) a simple task. Using IMAQ Vision package, I want to convert a greyscale (SGL) "*.AIPD" Image to a JPEG. I will post the code that I thought would work, but I'm obviously not understanding something fundamental to the images because it doesn't work and is giving me..'wrong image type'.
I'm stuck, again, and appreciate any help.
Thanks,
Jonathan

Convert png photos to jpeg

Help! My daughter took a photo on my iphone 4 that is saved as a png file. I can't pull it up in windows to print it out!
Thanks!

Hi,
Both of those cameras should be supported by PSE 12.
Just open the NEF file in the editor. It will first load the camera raw where you can do some adjustment.
When satisfied, make sure that the bit depth option is set to 8 bits/channel (bottom middle of camera raw window).
Click on Open Image to open the image in the main editor window.
Make any further adjustments you want to and then go to the File menu and select Save As
Change the format to JPEG, change the name if you want to and then click on Save.
You can adjust the quality on the next box (higher quality = larger file)
If you get a message about unsupported file format, it could be that you have use the old Nikon transfer program to copy the images from the card to your hard drive. This is knoow to cause corruption. See the following for a tool to correct the files.

Good luck

Problems Exporting RAW images to JPEG in Lightroom 1.1

I have used LR 1.1 with much success in editing, then exporting/burning JPEG images. But now, I am shooting in camera RAW (Nikon D40x), and when I attempt to export the edited images to JPEG files, I get the message that an error has occurred during export, and the files do not burn to jpeg. What can I do to correct this?

It will convert all images to jpegs, resize ... however you set it up ... and yes, it is so straightforward as it seems to be .
It makes no sense to upload RAW files to the web for public use in the first place. Second, LR does not touch/change the RAW files. Therefore, how would it be able to integrate your dev settings when using RAW on export?

Convert from RAW to Jpeg on iPad?

Do any of the 3rd party photography apps let you convert RAW images to Jpeg on the iPad itself?
Do any of them let you change the resolution, especially resize to 72 dpi for Web viewing?

I don't know of any applications that can access the actual RAW data.
Even the iPad photos app doesn't really understand RAW ... I believe that it is just showing you the embedded jpg that exists in all RAW formats.
I believe that some of the photo apps (such as "Photogene for iPad") can also read in the embedded jpg and resize / adjust / etc. the photo and then let you send the photo to other apps such as Facebook. How well this will work will depend on the size of the embedded jpg in the RAW format you use. My camera is the 5D mark II which has full resolution jpg files. Other cameras (like the original 5D) have much smaller embedded jpgs.

Converting Raw Images

I have photoshop elements 11. How do I convert RAW images to jpeg. I have over 800 to convert.

In the PSE Editor, select File->Process Multiple Files.
In general, I don't recommend bulk conversion of unedited RAWs to JPGs. You get the worst aspects of RAW and none of the benefits. The only time bulk conversion of unedited RAWs makes any sense at all is if you need to send them to someone else quickly.
