Local and private
Text processing runs in your browser. Toolbye does not upload your pasted content to a server.
Large text can be processed locally, with a warning when the input may be slow on older devices.
Copy and download actions use standard browser APIs. If a browser blocks clipboard access, the page shows an error.
Text Tools FAQ
Is my text uploaded?
No. The tool runs in the browser and uses local JavaScript functions for counting, cleaning, replacing, and comparing text.
Can I use regular expressions?
Yes. Enable Regex in Find & replace. Invalid patterns are reported before changing the result.
Does case conversion support code-style names?
Yes. You can output camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, and path/case.
How does text diff work?
The first version and second version are compared line by line using a stable LCS diff. It highlights added, removed, and unchanged lines.
What happens with very large text?
The tool keeps working but shows a performance warning for large input. For huge comparisons, line-level diff may take longer.
