Rules for Signature Uploads
Government exam portals (SSC, UPSC, IBPS, Railways, GATE) enforce strict signature criteria:
- Sign on clear white paper with black or dark blue ink.
- Crop tightly around the signature to remove extra white borders.
- Ensure the final file size is between 10 KB and 20 KB.
ImgDrop's client-side compression reduces the file size without pixelating the signature line, ensuring instant acceptance by automated form validators.
Frequently Asked Questions
How do I compress my scanned signature to under 20KB?
Drag and drop your signature photo into ImgDrop. The tool automatically configures a strict 20KB limit and optimizes contrast so ink strokes remain sharp and legible while the file size stays between 10KB and 20KB.
Why do exam portals reject my 20KB signature upload?
Most exam portals (like SSC, UPSC, and IBPS) require signatures to be in JPEG/JPG format, strictly between 10KB and 20KB, and with specific dimensions (such as 140x60 pixels). ImgDrop ensures your image meets both the format and file size limits.
Is my signature safe from being stolen or stored?
Yes, absolutely! Unlike other websites, ImgDrop processes images 100% locally inside your browser memory. Your signature is never uploaded, transferred, or stored on any server.
