Compress Image to 20 KB

Reduce a photo to under 20 KB in seconds — the target is already set to 20 KB, it keeps the best quality that fits and resizes only if it must. JPG output for forms. Free, nothing uploaded.

How to reduce an image to 20 KB

Drop a JPG, PNG or WebP above — the target is preset to 20 KB. FileQuick lowers the JPEG quality step by step until the file is just under 20 KB, and only scales the picture down if quality alone can't get there. It runs in your browser, so the photo never leaves your device.

20 KB is a common upload limit for exam signatures (SSC and IBPS cap them at 20 KB) and small passport-style photos. At this size you can expect about 350 × 450 px — the standard 3.5 × 4.5 cm exam photo — at decent quality.

Compress and resize mean different things: resizing changes the width and height in pixels, compressing changes how many bytes those pixels take. Most "resize image to KB" searches really need compression, which is what this page does first — it only resizes when the target is too small for the photo at its current dimensions.

The result is always a JPG, because that is the format online forms accept and the one that gets smallest. A PNG or WebP you drop in is converted automatically; transparency becomes white.

Crop to just the head and shoulders before compressing: fewer pixels of background means more bytes for the face.

Steps

  1. Drop your image (or several) onto the box above.
  2. The target is already 20 KB — change it if your form says something else.
  3. Click Compress. Each image is brought just under the target, and resized only if needed.
  4. Check the preview and file size, then download the JPG (or all of them as a ZIP).

Frequently asked questions

How do I reduce my photo size to 20 KB?

Upload it here — the target is set to 20 KB. The tool lowers quality until the file is just under 20 KB; a very small target on a large photo also reduces the pixel size, because quality alone can't reach it.

Will my image look worse at 20 KB?

Somewhat — at this size the picture has to be small or noticeably compressed. Cropping out empty background first keeps the face sharper.

Is "resize image to KB" the same as this?

Yes — when a form says "resize to 20 KB" it means the file size. This tool hits the file size; if you also need exact pixels (for example 200 × 230), use the Exam Photo Resizer, which does both.

Is my photo uploaded anywhere?

No. Compression runs in your browser with the Canvas API — the image never leaves your device.

Can I do several photos at once?

Yes. Drop as many as you like; each is compressed to 20 KB and you can download them together as a ZIP.
