How to Compress a Signature Photo
Exam portals like SSC (Staff Selection Commission), UPSC, and IBPS are extremely strict about signature file sizes. Typically, they require the signature to be between 10KB and 20KB. If it is 20.1KB, the portal will reject it.
Our tool makes this process seamless: you tell us exactly what KB target you need, and our browser-engine automatically recalculates the compression algorithms until your signature hits the perfect file size.
Is my signature secure?
Yes, 100%. Signatures are highly sensitive personal data. Unlike other compression websites that upload your image to their servers, FileHubTools processes everything locally inside your device's browser. Your signature never leaves your phone or computer.
