Free URL Encoder & Decoder Online
URLs can only safely contain a limited set of characters, so anything else — spaces, &, ?, =, non-English letters — has to be “percent-encoded” into a %XX form (a space becomes %20). Get this wrong and a link or an API call quietly breaks. This tool encodes text into URL-safe form and decodes it back, so you can build and debug query strings and links with confidence.
Frequently Asked Questions
- What is URL encoding?
- URL encoding (percent-encoding) converts characters that are unsafe in URLs — like spaces, &, =, and # — into a %XX hexadecimal format that can be safely transmitted.
- What's the difference between URL encode and URI component encode?
- URL encoding encodes the entire URL including slashes; URI component encoding (encodeURIComponent) preserves slashes and is used for individual query parameter values.
