Why “private PDF signing” matters

When you sign PDFs online, the biggest concern is where your document goes. This page is designed for users who want a simple signature workflow without accounts, and with local-first processing by default.

Practical privacy tip

Always confirm the exported PDF contains the signature exactly where intended. If you’re signing highly sensitive documents, avoid any tool that requires uploads unless you trust the provider and policy.

Sign a contract without uploading it

If you’re signing a sensitive document, you may prefer an editor that works locally in the browser by default, instead of sending your PDF to a third-party server.

Add initials to every page

Place your initials and signature wherever needed, then export a clean PDF ready for email or portals.

Sign on your phone (no app)

Open the editor on iPhone/Android, draw with your finger, and download the signed PDF instantly.

Finish a form fast

Type into fields, add date/name, then sign — all in one editor session so you don’t jump between tools.

What you can do on this page

This page launches the main editor (the same editor used on the homepage) so you can sign and finish the document end-to-end.
