Freesign – Free PDF Signing with Local Signature Embedding

Summary: Freesign enables users to sign PDFs directly in their browser without subscriptions or credit cards, offering three free signatures monthly. It embeds signatures locally using pdf-lib and applies a PAdES B-B cryptographic countersignature for verifiable authenticity.

What it does

Freesign lets users sign PDFs in-browser by embedding signatures locally before uploading. Each signed document receives a server-generated cryptographic countersignature to ensure integrity and verifiability.

Who it's for

It is designed for users needing occasional PDF signing without subscription barriers or trial limitations.

Why it matters

It removes paywalls and trial restrictions common in PDF signing tools, providing a secure, no-subscription alternative for authenticating documents.
