Compress Image to 40 KB

How to compress an image to 40 KB

1. Click the box above or drop your photo onto it. You can choose several at once.
2. Each image is saved under 40 KB at the highest quality that fits. It is a JPG unless you choose WebP or PNG under Output first.
3. Download the result. Its new size is shown next to it.

Frequently asked questions

Will the photo still look good?

The tool keeps the highest quality that fits under 40 KB. If that is not enough, it also reduces the width and height, and shows the new size next to the result. A limit as small as 40 KB suits the passport-style photos and signatures that application forms ask for.

Does 40 KB mean 40,000 or 40,960 bytes?

Sites count it differently, so the file is kept under 40,000 bytes, which is under the limit either way.

I need a different limit.

Use Compress Image and type any size in Target size (KB).

Are my photos uploaded?

No. Everything happens inside your browser, so your files never leave your device and nothing is stored on a server.
