Frequently Asked Questions
Will the image quality be bad at 20KB?
For small images (passport size, profile photos), 20KB is usually sufficient. For large photos, quality may be noticeably reduced. Try 50KB for a better balance.
Is my image safe? Does it get uploaded?
All compression happens in your browser. Your image is never uploaded to any server.
What if I can't get below 20KB?
Very large images may not compress to 20KB while remaining recognizable. Try resizing the image dimensions first using our Resize Photo tool, then compress.
