FAQ

Questions & answers

Everything you might wonder about this tool.

01When should I use component mode?
Use component mode for a single query-string value or path segment — it escapes reserved characters like &, = and /. Use the default mode for a whole URL you want to keep navigable.
02What gets encoded?
Characters that are not safe in a URL are replaced with percent-escapes (for example a space becomes %20).
03Is any of my data uploaded to a server?
No. This tool runs entirely in your browser with JavaScript — your input never leaves your device, so it is safe to use with private tokens, config and source code.
04Is it free, and do I need an account?
Yes, it is completely free with no signup, no install and no usage limits. Open the page and it works instantly on desktop or mobile.
