Shrinks the image to at most 20 KB
Twenty kilobytes is the classic small-avatar and upload-limit size. Plenty of forums, membership sites, and older web apps cap profile pictures and attachments around 20KB, and this tool gets your image under that line by lowering JPEG quality step by step — scaling the image too if it has to — until the file lands close to 20KB. It's an aggressive target, so photos lose some crispness, but a small avatar generally still reads clearly. Compression runs locally on a canvas in your browser.
Frequently asked questions
- Is 20KB enough for a profile picture?
- For a small avatar shown at 100–200px, yes — 20KB usually holds up because it's displayed small. For a large photo viewed full-screen it would look soft, but avatars are exactly the case this size suits.
- Why do forums cap uploads at 20KB?
- Small caps keep storage and bandwidth costs down and pages fast, which matters when a busy forum stores thousands of avatars. It's a common middle ground between quality and cost.
- The picture looks a little soft — can I improve it?
- Some softening is unavoidable at 20KB on a detailed image. Starting from a photo that's already cropped tight and not too large helps, since the tool then needs less aggressive compression.
