Frequently asked questions

Why does my signature compress to 8KB and get rejected?
Signatures on pure white backgrounds have very low visual complexity, so basic compressors overshoot and compress below 10 KB. PixelKit features automated padding and quantization tuning that keeps the file safely within the 10KB–20KB bracket.
Can I upload a smartphone photo of my signature?
Yes. Take a photo of your signature under good lighting without shadows. Drop the picture into PixelKit, crop closely around the ink strokes, and the tool will scale and compress it between 10KB and 20KB automatically.
