How local processing works
Understand when and how PDFHope processes files locally or through secure conversion infrastructure.
Your browser does most of the work
For local PDF tools, the browser grants the page temporary access to selected bytes and uses browser memory, PDF libraries, and canvas rendering to create a result locally.
Word to PDF and PDF to Word require a professional conversion engine. Those two pages upload a file only after you choose Convert, route it through PDFHope’s Cloudflare Worker, and process it with ConvertAPI in zero-storage mode.
What stays on this device
Favorites, recent tool routes, and theme preference are stored in localStorage. Processed filenames are not persisted by PDFHope. Closing the tab releases in-memory file data, subject to normal browser memory management.
Know the limits
Local processing is not the same as a formal security guarantee. For Word conversion, document bytes are transmitted over encrypted connections to Cloudflare and ConvertAPI for processing. Browser extensions, compromised devices, modified builds, and operating-system monitoring are outside PDFHope’s control.
