How FeelPDF keeps your files private
Most “online PDF” services upload your document to their servers, process it there, and promise to delete it later. FeelPDF is built the opposite way.
Processing happens in your browser
Every in-browser tool uses WebAssembly and JavaScript running on your device. The PDF bytes are read from the file you pick, transformed in memory, and offered back to you as a download. They are never transmitted anywhere.
You can verify it — “0 bytes uploaded”
The badge in the header counts every byte sent in any network request body. Open your browser’s developer tools, run any in-browser tool, and watch the Network tab: you’ll see no upload of your file — it has nowhere to go. (Word/Excel conversions are the one server-assisted exception, clearly badged.)
The one exception: Office conversions
Converting Word, PowerPoint and Excel files needs a full office engine that is too large to run in a browser. Those conversions use a single server hosted in the EU that processes your file in memory, writes no logs, stores nothing to disk, and deletes the file the instant the conversion finishes. These tools are clearly marked with an amber server badge.
Ads fund the free version — never your files
The free version is ad-supported and uses basic analytics, so we ask your consent for those cookies (Premium is ad-free). Either way, your PDF files are never shared with advertisers or anyone else — for in-browser tools they never leave your device.
Free or Premium, every in-browser tool processes your files on your own device and never uploads them — open your browser’s DevTools and verify it yourself.
