Maximum size

What 100 KB is good for

  • Websites and blogs: a 100 KB image loads quickly on phones and still looks sharp in an article.
  • Profile pictures and ID photos: many sites cap uploads at 100 KB.
  • Scanned documents: receipts and certificates stay readable at 100 KB if you crop the edges first.

How to get the best result

For a website, choose WebP under Save as: at the same 100 KB it keeps more detail than JPG. For forms, keep JPG. Use the before and after slider to check that text and faces look right before downloading.

Questions

What if my image is already under 100 KB?

It’s saved at high quality and stays under the limit. Nothing is made worse than it needs to be.

Why was my image resized?

Very large photos can’t reach 100 KB by lowering quality alone. The tool then reduces the pixel size just enough, and shows the new size under your file.

Does it work on iPhone and Android?

Yes. Tap the box to choose photos from your gallery or take a new one.
