Compress Image Between 10KB and 20KB — Photo & Signature, Free

Many forms set a band, not a cap — the file must be at least 10 KB and at most 20 KB, and a file outside it is rejected either way. This tool lands your photo or signature inside the 10–20 KB band: pick a target, and the result is never under the minimum or over the maximum. It runs in your browser; nothing is uploaded.

To compress an image to between 10 KB and 20 KB, upload it and pick the size you want inside the band; the tool re-encodes the JPG just under that figure and, if a very small file would fall below 10 KB, pads it up to the minimum without changing the picture. Forms that ask for 10–20 KB include SSC signatures, IBPS and bank signatures, UPSSSC and PAN.

100% private — your images never leave your device. No upload, no sign-up. Check it yourself: once this page loads, it works with your internet switched off.

How to compress image 10kb to 20kb

  1. Upload your image, or drag and drop it.
  2. Pick a target inside the 10–20 KB band.
  3. The tool re-encodes to just under the target and pads a too-small file up to 10 KB.
  4. Download — the file is inside the band whichever way the portal counts a KB.

FAQ

Frequently asked questions

01

Why does the form reject my file for being too small?

The notice sets a minimum as well as a maximum. A clean signature scan can be 5–8 KB, under a 10 KB floor. This tool pads the file up to 10 KB (1 KB = 1024 bytes, so it clears the floor however the portal counts) without changing how it looks.
02

Which size inside the band should I pick?

The highest the band allows keeps the most detail; the default is a safe middle. The result is always a little under the figure you pick, so it stays inside the maximum.
03

Can I convert a photo to 20KB?

Yes — "compress to 20KB" and "convert to 20KB" mean the same thing here. The tool re-encodes your JPG or PNG and shrinks it to fit 20KB, so you can convert any photo to a 20KB file that's ready to upload.
04

Is my photo uploaded anywhere?

No. The tool runs inside your browser, so your photo is read and processed on your own phone or computer and never sent to our servers or anyone else's. We never receive it, so we can't see, keep or share it — which makes it safe for sensitive documents like Aadhaar, PAN, passports and bank statements.
05

Is this tool really free? Is there a daily limit?

Yes, it's free with no daily limit. Because the work happens on your device, an extra photo costs us nothing — so there's no cap, no watermark and no account needed. Process as many files as you like.
