Frequently Asked Questions

Will my signature or small photo upload still look clear?

The tool keeps the highest quality that still fits under 20 KB. Very large photos may lose some detail because the size limit is strict.

Is my photo uploaded anywhere?

No. The photo is processed inside your browser and never leaves your device.

What file type do I get?

A JPG file. PNG and WebP photos are converted to JPG so they can reach the size limit; transparent areas become white.

What if the form wants exact pixel size too?

Use the Image Resizer first to set the width and height, then compress to 20 KB here.
