What is URL Encoder / Decoder?
URLs can only contain a limited set of characters, so spaces, accents and symbols must be percent-encoded — turning a space into %20, for example. A URL encoder and decoder converts text into this safe form and decodes encoded URLs back into readable text.
The tool offers both full-URL encoding, which preserves structural characters like slashes and colons, and component encoding, which escapes everything for use inside a single query parameter.
How to Use the URL Encoder / Decoder
- Paste a URL or text into the input box.
- Click Encode for a whole URL, or Encode Component for a parameter value.
- Click Decode to turn an encoded string back into readable text.
- Copy the result to use in links or code.

Benefits & Use Cases
Developers build query strings, share links with special characters, and debug encoded parameters. Marketers create tracking URLs, and anyone sharing a link with spaces or symbols benefits from proper encoding so the link works everywhere.
Everything is processed in your browser, so even private URLs and parameters stay on your device.
The URL Encoder / Decoder is completely free, needs no sign-up or installation, and runs entirely in your browser — nothing you enter is uploaded to a server, so your data stays private. It works on desktop, tablet and mobile, in light or dark mode.
Tips & Best Practices
Use Encode for a whole URL (it keeps structural characters like : / ? intact) and Encode Component for a single value that goes inside a query parameter (it escapes those characters too). Getting this distinction right is the usual fix when a shared link breaks after a space or an ampersand.
Building tracking links and API requests is the common job here. Turn a page title into the path portion with the Text to Slug tool, and switch to Base64 when you need to encode binary-style data rather than URL text.
FAQ about URL Encoder / Decoder
What is the difference between Encode and Encode Component?
Encode keeps URL structure characters like : / ? intact, while Encode Component escapes them too, which is correct for a value placed inside a query parameter.
Why does a space become %20?
Spaces are not allowed in URLs, so they are replaced with their percent-encoded form %20 (or sometimes a plus sign in query strings).
Can it decode any encoded URL?
Yes, as long as it is validly percent-encoded. Malformed sequences will show an error so you can fix the input.
Does it support non-English characters?
Yes. International characters are encoded using UTF-8 percent-encoding and decoded back accurately.
