Quick answer

BatchSet compresses a photo to 20 KB free and entirely in the browser: nothing is uploaded and no account is needed. It searches for the highest JPG quality that fits 20 KB and scales the photo down only when quality alone cannot get there, showing the final size and dimensions. Several photos can be done at once and downloaded as a ZIP, and the target can be changed to any size in KB.

How to use the Compress to 20 KB

Three quick steps — free, private, right in your browser.

1

Add your photo

Drop a JPG, PNG, WebP or iPhone HEIC photo, or click to pick one. Add several if you need them all at 20 KB.

2

It compresses right away

The tool tries the highest quality that still fits 20 KB. If no quality is small enough, it scales the photo down until it is, and shows you the new dimensions.

3

Download

Save the JPG, or download them all as a single ZIP.

Frequently asked questions

Is compressing to 20 KB free?+

Yes. There is no account, no credit and no watermark. It runs in your browser, so it costs us nothing to give away.

Are my photos uploaded?+

No. The whole thing runs on your own device: the photo is read, compressed and saved without ever being sent to us. That is also why there is no queue and no size limit from our side.

Will a 20 KB photo still look all right?+

20 KB is very small, so a full phone photo has to be scaled down as well as compressed. For a form photo or signature, which is what 20 KB is usually for, the result is fine. The card shows the final size in pixels so you can check.

What if my photo cannot reach 20 KB?+

You get the smallest version the tool could make, with a note saying so, instead of a file that pretends to be 20 KB. You can then try a smaller crop or a plainer background.

Does the output have to be JPG?+

Yes. Only a lossy format like JPG can be driven to an exact size, and forms that ask for 20 KB expect JPG anyway. PNG and HEIC photos are converted for you.

Can I do several photos at once?+

Yes. Add as many as you like and download them together as a ZIP. Each one is compressed to 20 KB on its own.
