URL Encoder & Decoder: Fix Broken Links and Query Strings
9 min read
URLs can contain spaces, ampersands, and other characters that break links or get stripped by systems. URL encoding replaces those characters with a percent sign and hex code (e.g. space → %20) so the link works everywhere.
When to encode
- Building links with spaces or special characters.
- Adding query parameters that contain &, =, or non-ASCII text.
- Passing URLs inside JSON or other formats that treat certain characters specially.
When to decode
- Reading encoded URLs from logs or APIs.
- Fixing links that show %20 or %26 instead of spaces or ampersands.
- Debugging redirects or share links.
Encoding and decoding are reversible: encode for safe transport, decode to get back the original. Our URL Encoder/Decoder does both in your browser. Paste a URL or string, choose encode or decode, and copy the result. No data is sent to our servers.
