Upload limits

This tool uses a fixed target and does not depend on a service limit.

How it works

Choose a photo — JPG, PNG, WebP or iPhone HEIC.
Adjust the crop frame if the target needs a fixed shape.
The tool searches for the best quality that fits the size and pixel requirements.
Download the result. Location and camera data (EXIF) are removed.

Didn’t fit? What to do

Signatures: sign with a dark pen on plain white paper and crop tight around the signature.
At 20 KB, a smaller image in pixels looks sharper than a large, heavily compressed one.
Scan or photograph signatures in even light: gray shadows around the ink take up bytes.
Remove borders and empty space before compressing.

Frequently asked questions

Why is my 20 KB photo blurry?

20 KB is very little data. The tool lowers the pixel size when quality alone is not enough; cropping to just the face or signature gives the sharpest result.

How do I resize a signature to 20 KB?

Sign on plain white paper, photograph or scan it, crop tight around the signature and pick the image here. The result is a JPG of 20 KB or less.

What pixel size should a 20 KB photo have?

Use the size the form specifies. If it gives none, a small image a few hundred pixels wide stays sharper at 20 KB than a full-size phone photo.
