Under 20 KB Compression FAQs
How do I reduce my signature file size to less than 20 KB?
Upload your scanned signature to our free online compressor. The tool runs an automated client-side binary search across JPEG quality settings to compress the file below 20 KB while preventing the file from dropping below the minimum 10 KB requirement.
What happens if my signature file is larger than 20 KB?
Almost all Indian exam portals (like SSC, IBPS, and State PSCs) employ strict client-side validation that will display an error message such as "File size must be between 10 KB and 20 KB" and prevent form submission.
Does reducing signature size below 20 KB affect signature legibility?
When done correctly using our 100% white backing fill and targeted binary search, the contrast of the ink strokes against white paper is preserved with crisp definition, preventing blur or compression artifacts.
Can I compress my signature from mobile without installing apps?
Yes, SignatureResizer.in works completely in your mobile web browser (Chrome, Safari, Firefox). You do not need to download or install any suspicious third-party apps or APKs.
