Free PDF Library — Read, Organize & Protect
Work with PDFs as a library instead of one file at a time: read and browse documents, organize pages and collections, and protect files with encryption. Built for managing many PDFs — where single-file merge and split tools stop being enough. Runs entirely in your browser; documents never leave your device.
PdfCraft
Read, organize, and protect your PDFs — a whole library, not one file at a time.
First launch downloads ≈13 MB, then it's cached for a year. Nothing is uploaded — your files stay on this device.
This is a desktop-class app — it works best on a larger screen.
Quick Answer
This free PDF library lets you read, organize, and protect PDF documents in your browser: browse documents comfortably, arrange pages and collections across files, and encrypt documents to control who can open them. It is built for the job of managing a collection of PDFs, and it runs entirely on your device — documents are never uploaded. Encrypted documents stay encrypted while you work with them.

Frequently Asked Questions
How is this different from the site's other PDF tools?
The merge, split, sign, and rotate tools each do one job on one file — perfect for quick tasks. This is PdfCraft, a full PDF application for the times you have many documents: a reader for comfortable viewing, organization across your library, and protection with encryption. Use the quick tools for one-off edits and this for managing the collection.
Are my PDFs uploaded anywhere?
No. The application runs as WebAssembly in your browser, and documents are read, organized, and saved locally. There is no server-side processing, and encrypted documents remain encrypted throughout — the app never needs your documents on a server to work with them.
Can it protect a PDF with a password?
Yes — protection with encryption is one of its core jobs. You can apply encryption to documents you need to share, and open encrypted PDFs you own. For a single quick protect or unlock operation on one file, the dedicated Protect PDF and Unlock PDF tools on this site are faster to open.
Does it replace a paid PDF suite?
For reading, organizing, and protecting, it covers the daily workflow of keeping a PDF collection in order — the part most people actually use Acrobat for. Specialist print-production features of the big suites are not the focus. Combined with this site's free merge, split, sign, and converter tools, most PDF work costs nothing.
Is it free, and are there limits?
It is free with no account, no page limits, and no watermarks. The software is open source under MIT and Apache-2.0 licenses, embedded exactly as its authors publish it.
