About
Signing documents
shouldn't be
complicated.
DocSignHub was built on a simple belief: you should be able to sign a PDF in under 30 seconds without creating an account, installing software, or handing your documents to a third party.
Our story
Born from frustration.
Founded in 2025, DocSignHub was born from the frustration of having to sign up to yet another SaaS product just to add a signature to a single PDF. We wanted something fast, private, and free — so we built it.
All document processing happens entirely in your browser using PDF.js and pdf-lib. Your files are never uploaded to any server. We don't store anything, because we never see anything.
Security first
Your documents are processed entirely on your device. We have no servers that touch your files — ever.
Speed matters
From upload to download in under 30 seconds. No loading screens, no waiting, no server round-trips.
Privacy by design
No accounts, no tracking beyond basic analytics, no selling your data. Simple and uncompromising.
