PDF Transformer

This is a prototype/proof-of-concept only. It sort of works, but contains approximately 509 bugs. Use at your own risk.

Tool used to 1: Convert a PDF into an HTML form, and 2: Fill that PDF with captured data. Works with signatures (pasted images only, not cryptographic signatures).
