PDF Manager
Upload, organize, and read your PDFs — all stored locally in your browser, never on a server
No PDF files yet
Upload your first PDF to get started — everything stays local in your browser.

Why it stays fast on big documents
- Surgical edits — pdf-lib copies only referenced objects, so deleting one page of a 500-page file doesn't rewrite the other 499.
- Thumbnail cache — previews render once and persist while you edit.
- No quality ladder — pages keep original streams; nothing silently resamples.
- Limits — practical ceiling around 200 MB documents (browser memory); beyond that use the server-side compressor.
How it works
- 1
Upload your PDFs by dragging them onto the page or clicking to browse — each file stays local in your browser.
- 2
Browse your library with cover thumbnails, search by name, rename or delete files anytime.
- 3
Open any PDF in the built-in viewer — read, zoom, navigate pages, and download with one click.
A full workbench, not a toy demo
Split, merge, rotate, delete, reorder and number pages client-side with instant visual feedback — files never leave the browser tab.
Library kept in IndexedDB
Uploaded PDFs stay in your browser's IndexedDB storage, so your collection survives page reloads and browser restarts. Every card shows the file name, its page count, and its size, and a storage bar tracks how much space the library occupies.
Search, rename, delete
Filter the growing library by name from the search box, rename files to fit your own filing system, and remove PDFs behind a confirmation prompt. All of it happens in one thumbnail grid.
Reader with zoom and search
Open any PDF in the built-in viewer and zoom from 25 to 400 percent, rotate pages, jump by page number, or go fullscreen. The viewer's own search finds words inside the document, and a download button exports any file.
Zero-upload privacy
All operations run in-tab via WebAssembly — sensitive contracts and IDs never touch a network request.
Frequently asked questions
Are my PDFs uploaded to a server?⌄
Never. All files are stored in your browser using IndexedDB, a local database. Nothing is ever sent to any server — safe for confidential documents.
How many PDFs can I store?⌄
The limit is your browser's storage quota — typically several gigabytes. The storage bar at the top shows your usage so you always know when you're near the limit.
What happens if I clear my browser data?⌄
Clearing your browser data will remove stored PDFs. Download important files first using the viewer's Download button.
What PDF features does the viewer support?⌄
The viewer uses Firefox's PDF engine. Zoom, fit-to-width, navigate with arrow keys, and download. Password-protected PDFs are not supported yet.

What Is a PDF Manager?
A PDF Manager is a personal document library that lives inside your browser. Instead of scattering contracts, e-books, and receipts across download folders, email attachments, and USB drives, you bring them into one place: a searchable grid of thumbnail cards, with every file stored locally in your browser's IndexedDB. The manager keeps the original file, its page count, and its name together, so you can find the right document in seconds. It is built for anyone who regularly collects documents and wants an orderly, private archive that needs no cloud service, no account, and no upload. Because the library lives in your browser, it works even on shared computers where nothing can be installed, and it needs no login of any kind.
What this tool can do
- 📥 Drag and drop PDFs into your library, or pick them from your device, and see each file's page count instantly
- 🔍 Search your collection by file name and filter the grid down to exactly what you need
- ✏️ Rename any document without leaving the page, so titles actually mean something
- 🗑️ Delete files you no longer need and keep the library tidy
- 👀 Open any PDF in the built-in viewer with zoom, fit-to-width, page navigation, and a download button
- 📊 Watch a storage bar that shows how much of your browser's space the library uses
When you'll use it
- 📄 You collect contracts, statements, and manuals and want them findable in one private place
- 📚 You keep e-books or course handouts and want thumbnails instead of a wall of file names
- ✈️ You are traveling with only a browser and need your documents handy without a cloud account
- 🖨️ You want to open and read a PDF with clean page navigation before printing or sharing it
Everything runs locally: your PDFs are stored in your browser's IndexedDB and are never uploaded to any server. Because storage lives in the browser, clearing your browser data removes the library, and very large collections are limited by the space your browser allows — keep important files backed up.
