Signature PDF

Free web app to sign, organize, edit metadata, and compress PDFs — self-hosted or via public instances.

Webfreeglobal

A free web application for signing and managing PDF documents, offering single- and multi-signature workflows, page operations (merge, rotate, extract), metadata editing, and file compression; it supports encrypted server-side storage and digital signing using poppler/NSS certificates. It can be self-hosted on Debian, Docker or Alpine systems or used via community-run public instances, and is aimed at individuals, nonprofits and organizations seeking a privacy-conscious, no-cost PDF signing and editing option rather than enterprise audit or qualified-signature capabilities.
