About PDFey
Why PDFey exists
I kept running into the same problem. Need to merge two contracts? Upload them to some website and hope they don't keep a copy. Want to remove a password from your own PDF? Pay $12/month for software you'll use once.
That didn't sit right with me. So I built PDFey — a set of PDF tools where everything runs directly in your browser. No file ever leaves your device. No server processes your data. It's just JavaScript doing the work right on your machine.
The result? You get 13 tools that handle most PDF tasks. Merging, splitting, compressing, converting, password-protecting — all free, all private. And you don't even need to create an account.
Who built this
I'm Martin Šikula, a developer from the Czech Republic running Sikulovi s.r.o. — a small company that builds free web tools. PDFey is one of several projects I maintain, alongside image tools (Pictey), developer utilities (CodeUtil), and others.
I care about making tools that are genuinely useful. Not tools that look good in a demo but fall apart with real files. PDFey handles large documents, preserves quality, and works even on slower connections because there's nothing to upload.
What makes PDFey different
No waiting for uploads
Drop your file and it starts processing immediately. No progress bars waiting for network transfers.
No accounts, no tracking
Open the tool, use it, close the tab. We don't ask for your email, and we don't track which files you process.
Works on any device
Desktop, tablet, phone — any modern browser. Install as a PWA to use it offline too.
All 13 tools
Each tool does one thing well. Pick the one you need:
- Merge PDF - Combine multiple files into one document
- Split PDF - Pull out specific pages or split into chunks
- PDF to JPG - Turn PDF pages into JPG images
- JPG to PDF - Bundle images into a single PDF
- Compress PDF - Shrink file size for email or upload
- Rotate PDF - Fix upside-down or sideways pages
- Delete Pages - Remove pages you don't need
- Reorder Pages - Drag pages into the right order
- Protect PDF - Lock a PDF with a password
- Unlock PDF - Remove password protection (you'll need the password)
- Flatten PDF - Bake form fields and annotations into the page
- Add Watermark - Stamp "Confidential" or custom text on pages
- PDF Metadata - Edit title, author, and other hidden properties
How it works under the hood
PDFey runs on Next.js with React and TypeScript. For the actual PDF work, I use two well-tested libraries: pdf-lib handles all the manipulation (merging, splitting, adding pages), while Mozilla's PDF.js takes care of rendering previews and conversions.
Both libraries run entirely in the browser. That's the whole point — when there's no server involved, there's no server to hack, no database to leak, and no middleman handling your documents. The app works as a PWA too, so once loaded, you can use it even without an internet connection.
