Local-first. No server processing
Private PDF tools for sensitive documents
MendPDF provides a complete suite of PDF tools: editing, conversion, merging, splitting, compression, and encryption, that process documents locally in your browser. Designed for teams and individuals who handle confidential, sensitive, or regulated content.
Why privacy-conscious teams choose local-first tools
Organizations handling legal documents, financial records, HR files, medical forms, and compliance materials face a fundamental tension: they need modern PDF tools, but most online options require uploading documents to third-party servers. MendPDF resolves this by processing everything locally.
Complete tool suite with local processing
Edit PDF: In-place text editing with bold, font, color controls and full RTL support. No upload.
PDF to Word: Convert to editable .docx with layout retention. Processed in browser.
Merge & Split: Combine or extract PDF pages without server involvement.
Compress: Reduce file size locally by stripping metadata and optimizing structure.
Protect & Unlock: Add or remove password encryption. Encryption happens on your device.
Watermark & Page Numbers: Add watermarks and numbering locally.
Architecture designed for privacy
All core tools use a WebAssembly engine that runs inside the browser. No server communication during processing.
Files exist only in browser memory and are discarded when you close the tab.
No document content is logged, analyzed, cached, or shared with any third party.
Magic Scan (phone scanning) uses end-to-end encryption with 60-second auto-deletion on the relay.
