Privacy-First Document
Intelligence
SanPDF Pro is a professional-grade suite of PDF and image utilities built for the modern web. We prioritize your privacy by processing every file directly on your device, ensuring your sensitive data never touches a server.
Built out of frustration, maintained for your absolute privacy.
We've all been there: uploading a sensitive contract, tax record, or resume to a random website, silently worrying about where those files actually end up. SanPDF Pro was born out of a simple desire to solve this problem once and for all. By running code directly in your browser, your files stay yours — local, encrypted, and 100% private.
For Students
Merge study guides, compress assignments, and convert images for submissions without paywalls or watermarks.
For Professionals
Safely manage confidential client records, NDAs, and invoices without cloud security risks.
For Daily Tasks
Quickly split, combine, or sign documents right from your browser without installing heavy software.
Professional-grade tools, accessible to everyone, everywhere.
SanPDF Pro was founded on a simple belief: you shouldn't have to choose between convenience and privacy. Most online tools require you to upload sensitive documents to remote servers, creating unnecessary security risks. We knew there was a better way.
By leveraging cutting-edge WebAssembly (WASM) technology, we've moved the processing engine from the cloud to your browser. This allows us to offer professional-grade tools—like PDF merging, splitting, and image conversion—that are lightning-fast, completely free, and 100% private.
