Introduction
The URL Encoder percent-encodes text so reserved characters do not break query strings, redirects, or OAuth parameters. It is not encryption—only safe transport in URL components. Typically you encode individual query values (similar to encodeURIComponent), not whole URLs the same way. Decode with the URL Decoder when inspecting real links. Double-encoding and missing encoding often cause 404s and bad redirects; encode once at the boundary and decode when reading values back. Pair with the URL Parser when you need structured components.

How to use
- Paste the plain text you need inside a URL component.
- Encode to percent-escaped form.
- Copy the encoded value into your query string or redirect URL.
- Test the full URL in a browser or HTTP client.
- Decode with URL Decoder when you need to reverse the process.
Use cases
- Encode search terms and filters in query parameters
- Build marketing URLs with UTM parameters safely
- Debug redirect chains that mishandle special characters
- Prepare strings for OAuth state parameters
- Normalize values before signing URLs
FAQ
- encodeURI vs encodeURIComponent?
- encodeURIComponent is more aggressive and is typical for query values. Encode full URLs differently.
- Why does my URL still break?
- Check for double encoding, missing encoding, or wrong component boundaries.
- Is encoding encryption?
- No. It is encoding for safe transport in URLs.
- Can I decode here?
- Use the URL Decoder tool for the reverse operation.
- Is this free?
- Yes. DevToolDock provides URL encoding for free.
