Compress image to 10KB

Bring a photo or signature under 10 KB for online forms.

or drop them here · paste with Ctrl+V

What it does

Some online forms only accept tiny files, often 10 KB or less for a scanned signature or thumbprint. Drop your image here and it will be brought under 10 KB, scaled down if lowering the quality isn’t enough.

How to use it

  1. Click “Choose images”, drop one or more images onto the box, or paste with Ctrl+V (⌘+V on a Mac).
  2. Each image is brought under 10 KB. If lowering the quality isn’t enough, it’s also scaled down, and a note tells you the new size.
  3. Check the final size next to the download button, then download the file or get everything as a ZIP.

Common uses

  • Scanned signatures for government and exam forms
  • Thumbprint or initials uploads
  • Tiny thumbnails for systems with strict storage limits

Tips

  • Crop tightly around the signature before compressing.
  • Use black ink on white paper: high contrast compresses far better than grey pencil.

Questions

How can a photo fit in 10 KB?

Only by getting small: at 10 KB an image usually ends up a few hundred pixels wide. That’s fine for signatures and small ID photos, which is what forms with this limit expect.

How do I get a sharp signature at 10 KB?

Sign with a dark pen on plain white paper, avoid shadows, and crop tightly around the signature before compressing. Less background leaves more of the 10 KB for the signature itself.
