How to Compress a Photo to 20KB, 50KB or 100KB (Free, Online)

Many exam and government websites only accept a photo under a fixed size — 20 KB, 50 KB, 100 KB, 200 KB and so on. If your photo is bigger, the upload fails. Here is how to compress any photo to an exact KB size for free, without losing much quality.

Why do forms ask for a small KB size?

Government and exam portals handle lakhs of uploads, so they cap the file size to save space and keep the site fast. A modern phone photo is 2–5 MB, which is far above these limits, so you must compress it first.

How to compress a photo to an exact size

  1. Open the Compress Image tool — It has one-tap presets for 10, 15, 20, 30, 50, 100, 200, 300 and 500 KB.
  2. Upload your photo — Choose the photo from your device — JPG or PNG.
  3. Pick your target size — Tap 20 KB, 50 KB, 100 KB, or type a custom size.
  4. Download — The tool finds the best quality that still fits under your target and gives you the file.
💡 Choose the largest size the form allows (for example 50 KB instead of 20 KB) — a slightly bigger file looks clearer.

Does compressing ruin the photo?

A good compressor keeps the best possible quality for the size you choose. For a passport-style photo at 20–50 KB the result still looks sharp enough for any form. Unpass compresses the image on your own device, so your photo is never uploaded to a server.
