Your Security Is Our Priority
We built Pdfwithmagic so your sensitive documents never have to leave your device. Here's exactly how we protect your data.
Browser-Only Processing
All PDF and image operations happen directly in your web browser using JavaScript and WebAssembly. Your files are loaded into your device's RAM, processed locally, and the result is downloaded — all without any network requests.
Zero Server Uploads
Unlike competitors who upload your files to cloud servers, we have no file processing servers. Our infrastructure only serves the website itself — HTML, CSS, and JavaScript. Your documents never leave your device.
No Data Collection
We do not collect, store, log, or access your files in any way. We have no ability to see what documents you process, how many pages they have, or what content they contain.
HTTPS Encryption
Our website is served exclusively over HTTPS with TLS 1.3 encryption, ensuring that the web application code you load is authentic and hasn't been tampered with during transit.
Automatic Cleanup
Once you close the browser tab or navigate away, all processed files are automatically purged from your browser's memory. There is nothing cached or stored permanently.
Open Architecture
Our client-side processing approach means you can verify our security claims yourself. Use your browser's Developer Tools (Network tab) to confirm that no file data is sent to any external server during processing.
