Signatures, photos and the 20KB field
Nothing on the modern web is stricter than the upload fields on exam registrations and government job applications: photo under 20–50KB, signature under 10–20KB — while your phone produces 5MB images. Most compressors can't get anywhere near that by lowering quality alone.
This tool can, because it treats dimensions as part of the budget: it finds the best JPEG quality that fits, and when 20KB demands it, scales the image down to the size those fields were actually designed for. For signature fields, just change the target to 10.
How to use it
- Add your photo or signature — the 20KB target is preset (set it to 10 for signature fields).
- Click Compress to 20 KB.
- Download each image, or all of them as a ZIP.
Frequently asked questions
How can a photo fit in 20KB?
Quality search plus smart downscaling — 20KB fields expect small images, and the tool produces exactly what the budget allows.
My form wants a 10KB signature. Can I do that?
Yes — change the Max size box to 10. Scanned signatures compress extremely well at small dimensions.
Is my photo uploaded anywhere?
No. Everything runs in your browser — your ID photo never touches a server.
