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 tool, and watch the Network tab: you will see no upload of your file. Our Content-Security-Policy (connect-src 'self') makes it technically impossible for the page to send your file to a third party.
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.
No accounts, no cookies, no tracking
FeelPDF sets no tracking cookies, loads no third-party analytics, and self-hosts its fonts and code. The only thing stored on your device is your theme/language preference. Because we don’t track you, there’s no cookie-consent banner to click away.
FeelPDF is open source under the AGPL-3.0 licence, so anyone can inspect exactly how it handles your files.
