How compressing to 20 KB works

Choose your image and it is saved as a JPG of 20 KB or less. The tool tries the highest quality first and lowers it step by step until the file fits. If even low quality is too big, it makes the picture smaller in pixels and tells you the new size.

Signatures

Crop the scan to just the signature before you compress it. Less empty paper leaves more of the 20 KB for the ink, so the signature stays sharp. Dark ink on white paper compresses best.

Photos

20 KB is small for a photo, so expect the tool to reduce the pixel size of a phone photo. Crop to the face or subject first to keep more detail where it matters.

Frequently asked questions

Will the file be exactly 20 KB?

It will be 20 KB or just under. The tool finds the highest JPG quality that fits, so the file is as clear as it can be at that size.

Is my photo uploaded?

No. The image is compressed in your browser and never leaves your device.

What if the form also asks for a size in pixels?

Use Resize Image first to set the width and height, then compress to the file size here. Check the exact sizes the form asks for.
