You've seen both .jpg and .jpeg file extensions and wondered — are they different formats? The short answer: no, they are exactly the same.
Same format, different extension
JPEG and JPG are identical image formats. The only difference is the file extension length.
Historical reason
Early Windows systems limited file extensions to 3 characters, so .jpeg became .jpg. Mac and Linux kept the full .jpeg extension.
Both work everywhere
.jpg and .jpeg files open in every image viewer, browser and app. You can rename .jpeg to .jpg (or vice versa) with no effect.
Use JPG for compatibility
Most modern tools save as .jpg by default. Both are universally supported — use whichever you have.
Tips
- Check that the output looks correct before deleting the original
- Download immediately after processing — files may expire
- Works on desktop and mobile browsers
FAQs
Can I rename .jpeg to .jpg?
Yes — renaming the extension from .jpeg to .jpg (or vice versa) has zero effect on the image. The file is identical.
Which should I use when saving?
Either works. Most tools default to .jpg — use that for maximum compatibility.
Is one better quality than the other?
No — .jpeg and .jpg are identical formats. Quality depends on compression settings, not the extension.
