URL Encoder & Decoder Studio
100% Local Browser ProcessingDeveloper SuiteHow to Encode & Decode Web URLs Online
Convert reserved characters, query strings, and Unicode symbols to percent-encoding with 100% in-browser privacy.
Paste or Type Raw URL / Text
Paste your raw URL, query parameters, or percent-encoded text into the left input studio pane.
Select Standards & Space Mode
Toggle between Encode URI Component / Encode URI, and choose space encoding as %20 or + (form-urlencoded).
Copy Output or Inspect Params
Copy encoded/decoded URI results to your clipboard, download text files, or inspect parsed query key-value pairs.
URL Character Percent-Encoding Reference
Understand how reserved HTTP characters translate into percent-escaped byte sequences under RFC 3986.
| Character Type | Raw Input Sample | Percent-Encoded Output | Primary Use Case |
|---|---|---|---|
| Space Character | hello world | hello%20world or hello+world | Encoding spaces in search queries and form submission fields |
| Query Parameter Delimiters | name=Alex & age=28 | name%3DAlex%20%26%20age%3D28 | Preventing query parameter corruption in API endpoints |
| Special Characters & Slashes | https://meema.in/path?a=1/2#top | https%3A%2F%2Fmeema.in%2Fpath%3Fa%3D1%2F2%23top | Safely embedding full web URLs as nested query parameters |
| Unicode & Emoji Symbols | Café 🚀 München | Caf%C3%A9%20%F0%9F%99%82%20M%C3%BCnchen | Transmitting non-ASCII international characters over HTTP |

Frequently Asked Questions
About URL Encoding
Everything you need to know about URL encoding, percent-escapes, encodeURIComponent vs encodeURI, space modes (%20 vs +), and browser privacy.
100% Confidentiality
All URL encoding, decoding & parameter parsing runs locally on your computer. Zero text bytes touch any external server.
URL encoding converts reserved characters (like ?, &, =, /, #, spaces, and non-ASCII Unicode characters) into percent-escaped byte sequences (%20, %3A, %2F) so they can be safely transmitted over the internet inside HTTP URLs.
encodeURI() preserves full URI structural delimiters (like http://, ?, #, &) and only encodes unsafe characters. encodeURIComponent() encodes ALL reserved characters including slashes, colons, and question marks, making it ideal for individual query parameters.
%20 is the standard RFC 3986 percent-encoding for spaces. The plus sign (+) is used in application/x-www-form-urlencoded HTML forms. Meema URL Encoder allows toggling between both standards with one click.
Paste any full web URL into the inspector pane. Our tool automatically parses the URL into an interactive table breaking down the Protocol (https:), Host, Path, Hash (#), and individual Key-Value Query Parameters.
No! All URL encoding, decoding, query parameter parsing, and RFC 3986 validation execute 100% locally inside your browser's JavaScript engine. Zero data bytes touch any external server.
