Privacy & Security
🔒
Your files never leave your device
Unlike typical online converters, FileMagic processes everything entirely
inside your browser. Your PDFs, images, and sensitive documents are
never uploaded to any server — not ours, not anyone's.
There is no backend. There is no cloud storage. There is no queue.
⚙️
How it works
- When you open a file, it is loaded temporarily into your browser's RAM only.
- All conversion and processing is performed by open-source JavaScript libraries
(
pdf.js, pdf-lib, JSZip) running locally.
- Converted files are downloaded directly to your device — nothing is retained.
- Closing the tab immediately and permanently erases all file data
from memory. There is nothing to delete from a server because nothing was ever sent.

Open-source libraries used
- pdf.js — Mozilla's PDF rendering engine (BSD licence)
- pdf-lib — PDF creation and modification (MIT licence)
- JSZip — ZIP file creation in the browser (MIT licence)
- FileSaver.js — Cross-browser file download (MIT licence)
All libraries are loaded from the
cdnjs
public CDN over HTTPS. You can verify the integrity of any script via your
browser's DevTools → Sources panel.

Tips for maximum privacy
- Use Private / Incognito Mode to prevent local browser caching of visited URLs.
- Once the page has fully loaded, you can disconnect from the internet before
opening any file — all processing will still work.
- Audit the source at any time: open DevTools → Sources in your browser
to read
script.js and style.css directly.
- After downloading your converted file, close the tab to ensure all
in-memory file data is released immediately.
