Convert Images in Mac OS X: JPG to GIF, PSD to JPG, GIF to JPG, BMP to JPG, PNG to PDF, and more
Tips & Tricks - January 24th, 2010 - 3 Comments
You can convert many different image file formats in Mac OS X for free using the included Preview application. As of Mac OS X 10.6, Preview supports the following file types and will convert between any of them: GIF, ICNS, JPEG, JPG, JPEG-2000, Microsoft BMP, Microsoft Icon, OpenEXR, PDF, Photoshop (PSD), PICT, PNG, SGI, TGA, TIFF
Here’s a very simple walkthrough to convert images within Preview:
* Open the image file you want converted within Preview
* From the File menu navigate down to ‘Save As’
* Select the file format you want the image converted to from the ‘Format’ drop down list
* Click “OK” to save and convert the image to the new format
The above process will hold true regardless of the origin images file format and the desired file format.
Preview.app supports a wide range of image conversions: GIF to JPG, JPG to GIF, PSD to JPG, JPG to PDF, JPG to BMP, BMP to JPG, BMP to GIF, PNG to GIF, JPG to PNG, TIFF to JPG, and just about every other variation between these and more. As long as the image format is supported by Preview, it will convert it to any other supported file format.



Useful tip. Preview might be a bit unweildy for batch work but gets the jobs done.
Hello,
With Mac OS X Preview: 8Kb bmp image -> 12Kb gif
With Windows Paint: same 8Kb bmp -> 202b gif
Is there a better Macs OS X app to convert from bmp to gif?
Thanks,
