Frequently asked questions

Does it handle acronyms in Title Case?

Title Case capitalises the first letter of each word. Manually preserve acronyms after conversion if needed.

Are my files uploaded to a server?

No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.

Does it work on mobile?

Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
