Compress image to 20 KB: questions
Is my photo uploaded?
No. The file is read by your browser and processed on your device; nothing is uploaded to a server, so there is nothing for us to keep.
How does it get a photo under 20 KB?
It tries quality levels until it finds the highest one that fits under 20 KB. If even a low quality is too big, it reduces the width and height step by step, so the photo stays as sharp as the limit allows.
Any tips for 20 KB photos?
At 20 KB the picture has to get small: a passport-style photo still looks fine at about 200 to 300 pixels wide, which is usually what such forms display.
JPG or WebP?
Choose JPG when a form asks for JPG or JPEG, which most do. WebP is smaller at the same quality but is not accepted everywhere.
