PDF Metrix is a privacy-first, local-first document suite with 25 power tools.

Tools include Merge, Split, Edit Canvas, E-Signatures with SHA-256 Audit Trails, Redact PII, Compare, Compress, & Converters for Word, Excel, PPT, JPG, HTML, and Markdown — all 100% private and fully usable offline!

Hey Product Hunt community! We built PDF Metrix because we were tired of online PDF services requiring users to upload sensitive financial reports, legal contracts, and personal documents to unknown remote servers just to merge a few pages or compress a file. PDF Metrix brings server-grade C++ PDF processing engines directly into your web browser using WebAssembly. Your files NEVER leave your device memory! What you can do with PDF Metrix:" - 25 Power Tools: Merge, Split, Edit, Sign, Watermark, Redact, Compare, Compress, Protect, Unlock, & Format Converters. - 100% Offline PWA: Works even when disconnected from the Internet. - SHA-256 Cryptographic Audit Certificates for E-Signatures. - Zero Server Retention: 100% Zero-Knowledge Privacy Architecture.
