Choose a photo: the tool finds the highest JPEG quality that keeps the file under 20 KB and, if needed, makes the picture smaller. You see the final size before you download, and the photo never leaves your device.
Works in your browser: what you type or choose stays on your device and is not uploaded anywhere.
Where you need this

Questions
Will the photo still look good at 20 KB?
For a face or a signature, yes: the tool also shortens the longest side (often to 400–600 px), which keeps a small picture sharp. A wide landscape loses detail.
The form asks for 10–20 KB. Will the file fit?
Yes: the tool aims for the largest file that still stays under 20 KB, so it lands between 10 and 20 KB for almost any photo.
Does 20 KB here mean 20,000 bytes?
The file always stays under 20,000 bytes, so it fits both sites that count 1 KB as 1000 bytes and those that count 1024.
