Reduce any photo to 20 KB or less — no upload, no watermark, 100% private
100% private — images are compressed inside your browser and never uploaded to any server.
Choose your image above and click Compress — the tool automatically finds the highest possible quality that fits under 20 KB. It first tunes JPEG compression quality with a binary search, and only reduces the image dimensions if the size target can't be met by quality alone. You see the original size, the final size and the output dimensions, then download the result with one click. Multiple images can be processed in the same batch.
The 20 KB limit appears on government job portals, exam registrations and visa forms — especially for signature and passport-photo uploads. Most phone photos are 2–5 MB, over 100× too large, which is why portals keep rejecting them. The output is a standard JPG that every form portal, email system and website accepts.
Unlike most online compressors, this tool never sends your photo to a server. Compression happens inside your browser using the canvas API, so personal photos, ID images and documents stay on your device from start to finish. There's no watermark, no signup and no file limit per day.
