URL Encoder Decoder – Free Online Tool
Encode URI components, encode full URLs, decode escaped URL strings, parse query parameters, and batch-process lines locally.
Free URL Encoder and Decoder
The URL Encoder Decoder helps you safely encode query values, decode escaped URLs, and inspect query parameters. It is useful for debugging redirects, building UTM links, testing APIs, fixing malformed URLs, and sharing links that contain special characters.
EncodeURI vs EncodeURIComponent
Full URL encoding and query component encoding are not the same. encodeURI keeps URL structure characters readable, while encodeURIComponent escapes values that belong inside query parameters. This tool includes both modes so you can choose the correct output.
Best Use Cases for URL Encoding
Encode redirect URLs, decode analytics links, inspect UTM parameters from the UTM Builder, debug OAuth callback URLs, encode search terms, and safely pass email addresses or symbols through APIs.
Private and Instant
URLs can contain tokens, emails, campaign IDs, and private redirect paths. ToolsMint runs encoding and decoding in your browser without uploading the input.

- 1

Frequently Asked Questions
Everything you need to know about the URL Encoder Decoder.
Is this URL encoder free?
Yes. It is completely free with no signup.
What is the difference between Component and Full URL mode?
Component mode encodes a query parameter value. Full URL mode preserves URL separators like : / ? & while encoding unsafe characters.
Can I decode URLs with plus signs?
Yes. Decode mode treats plus signs as spaces, which is common in query strings.
Can it parse query parameters?
Yes. If the input contains query parameters, the tool shows a readable key-value preview.
Does it support batch conversion?
Yes. Enable batch lines to encode or decode each line separately.
Is my URL data private?
Yes. All processing happens locally in the browser.
