Why resize your image to exactly 10–20KB?
10–20KB is the standard signature file-size range accepted by SSC, UPSC, Railway, IBPS, NEET, and virtually every Indian government exam portal. Signatures must be small enough to upload quickly even on slow connections, yet clear enough for identity verification.
💡 Pro Tips for 10–20KB Images
- Sign with a dark black or blue pen on clean white paper for the clearest digital result.
- Crop tightly around your signature before uploading — less whitespace means better compression.
- Use natural light and avoid shadows when photographing your signature with a phone.
- JPEG format gives the best quality at this tiny file size.
