How PDFMagpie keeps your files on your device
Most online PDF tools upload your document to a server, process it there, and send it back. PDFMagpie works the other way round.
The short version
When you open a PDFMagpie tool, your browser downloads our code — not the other way round. When you choose a file, it is read into this browser tab’s memory and processed by that code on your own computer or phone. The finished file is saved straight to your device.
Your files, file names and passwords are never sent to our servers or anyone else’s.
What we use
- pdf-lib (open source) to combine, split and modify PDFs.
- PDF.js (open source) to draw page previews, with scripting switched off.
- Background “workers” so heavy jobs don’t freeze the page.
Check any PDF website yourself
- Open the site and press F12 (or right-click → Inspect) and choose the Network tab.
- Run a tool on a test file.
- Look for a request that is about the size of your file. If one appears, the site uploaded it.
On PDFMagpie you won’t find one — your file never leaves the tab.
What about ads and analytics?
Like most free websites, our pages load advertising and privacy-friendly analytics. These never receive your files. Ads sit below the tools, never next to your buttons, and the tools work perfectly with ad blockers. Our Privacy Policy has the full details.
