About Công Cụ Nhanh
Công Cụ Nhanh (Vietnamese for “quick tools”) brings the small tools everyone needs into one place: fast, focused, ready to use and respectful of your data.
What we do
Plenty of everyday jobs take longer than they should: compressing photos for an email, merging PDFs for an application, making a QR code for a flyer, finding the typo in some JSON. Công Cụ Nhanh does these in seconds with a clear interface and nothing to install.
Principles
- Process in the browser whenever possible: your images, PDFs and text are not uploaded to a server.
- Free to use, no account required.
- Only tools that work correctly and have been tested are published.
- Transparent results: calculations show their formula and errors are explained clearly.
- Ads, if shown, never cover or imitate the tool's buttons.
How the site is funded
The site may display ads to cover hosting and the development of new tools. Ads are always clearly labelled and kept apart from the area where you work.
