PDF Shelter
No cloud, no limits โ PDF tools that run entirely in your browser, so documents never leave your machine
Website: https://pdfshelter.com/ ยท License: Proprietary ยท Type: Free client-side web app
Why it exists
The standard online PDF tool works in three steps: upload your files to a stranger's server, let it process them, download the results. That's two transfers of potentially sensitive documents, waiting time for both, and server bills someone has to monetize โ usually with "free = 2 files/day" walls. PDF Shelter deletes steps one and three: it ships the processing code (built on Mozilla's pdf.js and pdf-lib) to your browser and does the work locally. No upload lag, no quota, no document ever touching a server.
Main features
- JPG to PDF / PDF to JPG โ build PDFs from images or extract pages as images.
- Merge & split โ combine many PDFs into one, or split a document among several.
- Delete pages โ remove any pages you don't need.
- No limits โ as many large documents as your device can handle, at zero cost.
- Fast & quota-friendly โ processing starts instantly since nothing transfers; great on metered connections.
Who it's for
- Anyone handling contracts, IDs or medical documents who refuses to upload them to random converter sites.
- People on slow or metered connections who don't want to shuffle big files back and forth.
- Office workers tired of "free tier: 2 documents per hour" signup walls.
How it compares
- iLovePDF / Smallpdf โ server-side processing with freemium limits; PDF Shelter is fully local and unlimited.
- PixlPDF (in this library) โ also keeps tools local and adds OCR, redaction and e-signing; PDF Shelter stays minimal by design.
- PdfDing (in this library) โ self-hosted PDF reading and management; PDF Shelter is the zero-install quick-fix toolbox.
- pdftk / qpdf CLIs โ more powerful, but require installation and command-line comfort.
Notes
- Client-side means your device does the work โ very large jobs are bounded by your browser's memory, not by someone's server.
- No account, no tracking of documents; the site's privacy policy covers standard web analytics only.
- Available in English, French, Portuguese and Spanish; tool set is growing ("more coming soon").
