When you’ll hit a 100 KB limit
Small upload limits are common on online forms: job and school applications, government portals, forums and profile pictures. If a site says your photo is too large, a file under 100 KB fixes most of them. Check the form for a pixel size too, since some ask for both.
If the photo won’t look good at 100 KB
- Crop away what you don’t need first. Fewer pixels leave more of the 100 KB for detail.
- Use JPEG for photos. PNG files are usually far too big for a 100 KB limit.
- Need a different limit, such as 50 KB or 200 KB? Use compress to any size.
Frequently asked questions
How do I get a photo under 100 KB?
Add it here and press Compress. The tool lowers the JPEG quality step by step until the file fits under 100 KB, and only shrinks the pixel size if quality alone isn’t enough.
Will my photo look worse at 100 KB?
A little, on a large photo. 100 KB is plenty for a profile picture or an ID-style photo around 600 to 1000 pixels wide, but a full-size phone photo has to lose some detail to fit.
Is 100 KB the same as 0.1 MB?
Yes, for most purposes. Some forms count 1 KB as 1,000 bytes and others as 1,024. This tool counts 1,000, so files stay under 100,000 bytes and fit either way.
Can I compress many photos to 100 KB at once?
Yes. Add up to 100 photos and each one is made smaller than 100 KB. Download them one by one or as a ZIP.
Are my photos uploaded?
No. Everything happens in your browser, on your device.
