About CanDoYa
CanDoYa is a growing collection of free online tools that run entirely in your browser. No uploads, no sign-up, no watching ads while a spinner turns. You open a page, the tool works, and your data stays on your device.

What we make
We build small, focused tools for everyday tasks: counting words, formatting JSON, encoding and decoding text, checking color contrast, and more. Each one does a single job well, loads fast, and gives you a useful result without extra setup. We add new English-language tools regularly as the collection grows.
Why everything runs in your browser
CanDoYa processes the files and text you give its tools on your device. The site serves the code, and some tools download an additional library or AI model before they can run. Your input is not uploaded to a server for processing.
Many tools keep working after they have loaded, but offline use depends on the tool and whether its required assets have already downloaded. The site also uses privacy-friendly analytics to understand page usage; see the privacy policy for details.
How we keep it free
The tools here are free and we intend to keep them that way. Some pages link to a paid app when a task needs more than a browser can comfortably handle, like processing large batches or saving your work across devices. Using those apps is always optional, and the free tools never depend on them.
