How to Sign & Lock PDFs Without Adobe (Free)
Adobe Acrobat is the industry standard, but it's expensive and bloated. If you just need to merge a contract or password-protect a sensitive tax document, you don't need a subscription.
The Problem with Online Signers
Most "Free PDF" websites require you to upload your contract to their server. This is a massive security risk. You are handing your legal signature and private data to a third party.
The Solution: Client-Side PDF Tools
We built PDF Architect to solve this. It runs entirely in your browser.
- Merge multiple files into one.
- Encrypt files with military-grade passwords.
- Zero Uploads: Your document never leaves your device.
