Compress an image to 20 KB

A 20 KB limit is small — it usually appears on signature and thumb-impression fields rather than photographs. This page starts with that limit already set.

Your file stays on your device. This tool runs entirely in your browser — nothing is uploaded to our servers, and nothing is stored.

How to compress an image to 20 KB

Important limitations

Worth knowing before you start, so nothing here comes as a surprise at the point you are submitting a form:

A detailed colour photograph at full resolution will not reach 20 KB while remaining recognisable. If the form asks for a 20 KB photo, it is also expecting small pixel dimensions — around 200 × 230.
The result is at or under 20 KB, not exactly 20 KB.

How your files are handled

This tool does its work using your browser’s own image and document engine. Your file is read from your device into the page’s memory, processed there, and offered back to you as a download. It is never sent to Fyleit, never written to a server, and never stored anywhere we can reach.

You can verify that for yourself: load this page, disconnect from the internet, and the tool still works. That is also why there is no sign-up and no email field — we have nothing to attach an account to.

Common problems

20 KB made my photo look blocky.

At that size, some loss is unavoidable. Crop tightly first so every kilobyte is spent on the subject, and reduce the pixel dimensions before compressing rather than relying on quality alone.

My signature turned grey and faint.

Heavy compression washes out thin pen strokes. Crop close to the signature and keep the output around 300 pixels wide — at that size the strokes stay solid even at a low quality setting.

Frequently asked questions

Are my photos uploaded to a server?

No. This tool uses your browser’s own image engine, so the photo is read, processed and saved entirely on your device. Nothing is sent to us, and nothing is stored. You can confirm this by opening your browser’s network tab, or by disconnecting from the internet after the page has loaded — the tool keeps working.

Why do forms ask for 20 KB?

Upload limits are set by whoever built the form, usually to keep storage and bandwidth down across millions of applicants. Always follow the limit printed on the form you are filling in, not a number you read elsewhere.
