Hi devs 👋
One thing most people don’t notice about AllInOneTools:
Almost everything runs inside your browser.
PDF compression.
Image resize.
QR generation.
Text tools.
SEO checks.
All processed locally using browser APIs.
Your files don’t get uploaded.
Your data doesn’t leave your device.
Only ~10% of tools touch the server,
and that’s mainly for things like:
API checks, external data, or security validation.
This design was intentional.
Because for small tasks, privacy and speed matter more than heavy backend processing.
Modern browsers are powerful enough to handle most utility work without servers.
Open → Do → Close — safely.
