Why Compress to 20KB?
Many official portals and government exam websites (such as SSC, UPSC, State PSCs) specifically request that signature images and sometimes thumb impressions be kept strictly under 20KB in file size. Uploading a larger file will result in an error on their application forms. Our tool is optimized to shrink your signatures down to 20KB while preserving the legibility of ink marks.
How we guarantee your privacy
Unlike conventional compressor sites that upload your sensitive documents to their servers, SizeSnap executes all image processing natively within your web browser using HTML5 Canvas and WebAssembly. Your files never leave your phone or computer.
