What happens to your document

1. Browser inputYour browser reads the file you select. Document bytes are not sent to a LocalPDF processing API.
2. Local resultThe tool performs the operation in this tab and creates its result in browser memory.
3. Your downloadYou choose whether to download the result. Browser memory is cleared when the page is closed or reloaded.

Why Process PDFs Locally?

Supported workflows process document bytes in the browser without a document-byte upload to LocalPDF. Device, browser, extension, download, storage, and later-sharing risks remain separate boundaries.
