URL Encoder/Decoder – Web Development
Encode and decode URLs for safe web transmission. Handle special characters, query strings, and URI components.
Our URL Encoder/Decoder encodes and decodes URLs and text for safe transmission in web applications. URL encoding converts special characters (spaces, unicode) to percent-encoded format (e.g., %20 for space). Essential for query strings, API parameters, and any URL containing special characters.
All encoding and decoding happens locally in your browser. Your data never leaves your device. Use Encode for preparing URLs or Decode for reading encoded strings.

Frequently Asked Questions
When should I encode a URL?
Encode when your URL contains spaces, special characters (+, &, =), or non-ASCII characters (Arabic, emoji). Encoding ensures the URL works correctly in browsers and APIs.
Is my data sent to a server?
No. All encoding and decoding happens entirely in your browser using encodeURIComponent/decodeURIComponent. Your text never leaves your device.
What characters get encoded?
Spaces become %20, & becomes %26, = becomes %3D, and unicode characters become percent-encoded UTF-8 sequences.
