How to tell where processing happens
If a tool works instantly offline, or keeps working after you disconnect from the internet, it runs on your device. AMPDF's PDF and image tools all do — the file is read into memory, processed, and handed back as a download.
Common private tasks, done locally
Everything below happens in the browser tab, with no account:
- •Merge or split a set of statements before sharing only the relevant part.
- •Rotate pages from a phone scan so they read correctly.
- •Delete pages you do not want the recipient to see.
- •Strip document metadata (author, software, timestamps) before sending.
What to still be careful about
Local processing protects the file in transit, not the content itself. Redaction should black out and remove the underlying text, not just draw a box over it. And once you download and email the result, normal email rules apply.
