At a Glance#

  • Ideal Size: 5–15 KB
  • Format: PNG (for better clarity) or JPG if specifically required
  • Essential Steps: Crop tightly → Clean background → Enhance contrast → Export smartly

Capture Method#

  • Use a plain white sheet with a dark ink pen and steady signature.
  • Click in natural daylight near a window; avoid flash or shadows.
  • Keep the phone or camera parallel to the sheet to prevent angled distortion.

Cleaning Process#

  1. Crop tightly using the Image Cropper.
  2. Increase contrast in the Signature Optimizer to remove gray paper texture.
  3. Ensure background color is pure white (#FFFFFF) for smaller KB size.
  4. Export in PNG for better sharpness, or in low-quality JPG if file limit demands it.

Reducing KB Size#

Signature images compress easily because most of their area is plain white. Still too large? Try tighter cropping and reduce extra padding. Phrase: “signature ko 10 kb me kaise kare?” — Answer: crop close, remove noise, and use PNG or balanced JPG compression.

Common Errors#

  • Gray or yellowish background: Poor lighting; use natural light.
  • Faded strokes: Use a darker, fresh pen (preferably blue or black).
  • Extra white space: Large margins increase file size unnecessarily.

FAQ#

  • Can I use a blue pen? Yes, blue or black both work fine. Avoid shiny or glitter pens.
  • Is scanning better than a photo? Not necessarily — a clear phone photo in daylight is perfectly acceptable.
  • How to make signature under 5 KB? Crop tightly and maintain strong contrast. The smaller the canvas, the lower the KB size.
