Why PDF Conversion Without Uploading Your Photos Is Safer

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Many services upload files to a server for conversion
  • This site processes everything inside your browser
  • You can verify yourself that no upload takes place

We often turn documents with personal information into PDFs: résumé photos, ID cards, transcripts. Where the file is processed matters more than people think.

How typical services work

Many online converters upload your file to a server, convert it there and send it back. Some keep files on the server for a while. What happens in transit or on the server is invisible to you.

How this site works

This site loads the conversion code into your browser and runs it on your device. The photos you choose are never sent out.

How to verify it yourself

On a computer, open the browser's developer tools on the "Network" tab and convert a file. You will see that no request carries your photo data. (On first load you will only see requests for the program libraries.)

Still worth keeping in mind

Because processing happens on your device, conversion works even on an unstable connection. The first page load does need a connection, though.
