Description
Free online tools upload your file to a server you know nothing about. OnDevice Tools can't - there is no backend. 64 utilities for developers and everyday work: JSON/XML/YAML/SQL formatters, regex tester, hashing, image compress/resize/convert, PDF merge and split, CSS generators, QR codes and financial calculators. Everything runs in your own tab. No sign-up, no upload, no limits. It works offline once loaded, and it's open source under AGPL so the claim is checkable rather than just stated.
