URL Encode / Decode
About URL Encode / Decode
Encode special characters so they can travel safely inside a URL, or decode percent-encoded strings back to readable text. Essential when building query parameters, API endpoints, redirects, and form values, where spaces, ampersands, and non-ASCII characters must be percent-encoded to avoid breaking the URL. Handles UTF-8 correctly, so emojis and international characters encode cleanly. Everything runs in your browser, so nothing is uploaded.
How To Use
- Paste your text to encode it for a URL, or paste a percent-encoded string to decode it.
- The converted result appears in the opposite panel instantly.
- Copy the output into your query string, redirect, or API call.
Example
Input: A search query like "café & croissant" that needs to go into a URL.
Output: The encoded form caf%C3%A9%20%26%20croissant, safe to use in a query parameter.
Who Uses URL Encode / Decode
- Developers who prefer private, browser-only tools for formatting, validation, and data work.
- Engineers who need fast local tools without installing anything or uploading code.
- Teams that want private — files and text stay on your device and are never uploaded to a server.
Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) converts characters that are not allowed or not safe in a URL — spaces, &, =, /, and non-ASCII text — into % followed by hex codes, so the URL stays valid.
When should I encode or decode?
Encode when putting user input or free text into a query string or path. Decode when you have received an encoded string and want to read the original text behind it.
Does it handle Unicode and emojis?
Yes. UTF-8 characters including emojis and non-Latin scripts are encoded correctly as multi-byte percent sequences, and decoded back without mangling.
Is my input uploaded anywhere?
No. Encoding and decoding run locally in your browser, so private URLs and tokens never leave your device.
