Quick answer

BatchSet compresses a photo to 50 KB free and entirely in the browser, with no upload and no sign-up. It picks the highest JPG quality that still fits 50 KB, which is the usual limit on exam and government form uploads, and only reduces the pixel size if it must. Batches download as a single ZIP.

How to use the Compress to 50 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 50 KB.

2

It compresses right away

The tool tries the highest quality that still fits 50 KB. If no quality is small enough, it scales the photo down until it is, and shows you the new dimensions.

Frequently asked questions

Is compressing to 50 KB free?+

Yes, with no account and no watermark. The work happens in your browser.

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.

How much quality is lost at 50 KB?+

Less than most people expect. The tool searches for the highest JPG quality that still fits 50 KB, so nothing is thrown away needlessly. A photo only gets scaled down when no quality setting is small enough.

Why do forms ask for 50 KB?+

Many exam and government portals cap uploads so their storage stays small and pages load on slow connections. The cap is on the file size, not the dimensions, which is why compressing works.

Can I use a different size?+

Yes. Change the number in the Target size box to anything from 5 KB upwards, or pick one of the presets, then compress again.

Can I do several photos at once?+

Yes. Add them all and download a single ZIP. Each photo is taken to 50 KB separately.
