How to Prevent Online Signature Rejections

Portals reject signatures primarily for two reasons: file size under 10KB (portal flags as too low quality) or file size over 20KB (portal rejects as too large).

By cropping tightly around the handwritten strokes and setting the target size to 14KB-18KB, you sit safely inside the allowed acceptance window.

Frequently Asked Questions

Why does the portal say file size is too small?

Government portals reject files under 10KB because they assume low resolution. PixEnhance lets you set target size to 15KB so it never falls below 10KB.

Can I use a smartphone camera photo of my signature?

Yes! Crop closely around the ink strokes and use our contrast optimizer to turn grey paper into clean white.
