File Handling & Security

Online PDF Edits is built on a "local-first" architecture. This means that when you upload a PDF to edit, the processing happens entirely within your web browser using WebAssembly technology.

Because we don't use a backend server to process your PDFs, we also don't have any database or storage where your files could be saved. Once you close the browser tab, any memory of the file is gone from the browser's temporary memory.

The connection between your browser and our website is secured using industry-standard TLS (Transport Layer Security) encryption. Even though files aren't sent to us, the delivery of the application code itself is secure.

Since files exist only in your browser's RAM (Random Access Memory), they are automatically and instantly "deleted" when you:

• Refresh the page
• Close the tab or window
• Clear your browser cache
