Complete Guide to Compressing Signatures to 10KB–20KB
Compressing digital signatures to between 10KB and 20KB is required by nearly all major examination boards including SSC, UPSC, IBPS, RRB, and state police recruitment boards. A signature file that is blurry or too heavy will result in application rejection.
Wyori is specially engineered to handle signature scans. When you take a photo of your signature with a smartphone, paper textures, shadows, and dim lighting cause file sizes to swell to 3MB–5MB. Wyori automatically analyzes ink contrast, purges background gray tones, and sharpens strokes so the final image is crystal clear under 15KB.
Always sign with a dark black or dark blue ink pen on clean white unruled paper for the best compression results.
