Offline-friendly PDF tools
Local processing means your document workflow does not depend on uploading to a SaaS API.
🚫 no upload
🌱 on-device
🆓 free
⚡ browser / Wasm
True installable offline apps still matter. GroundPDF is offline-friendly in a practical sense: once the page and Wasm engine are loaded, PDF bytes are processed locally and are not uploaded for the core tools.
A full PWA cache of every engine is on the roadmap. Today you already get the privacy win of no document upload.
Best offline-friendly workflows
- Merge + compress before sending email
- Sign and watermark without a signing cloud
- OCR a scan when you do not want the scan stored remotely
