URL Encoder and Decoder

URL Encoder & Decoder Free Online Tool

Our url encoder and decoder free online tool converts text and links into a safe URL format, and turns encoded strings back into readable text, in one click.

Free URL Encoder Online for Links, Queries and Parameters

This free url encoder online makes sure special characters such as spaces, ampersands, slashes and accented letters do not break your links. It is useful for query strings, redirect URLs, API requests, tracking parameters and form data. If you are also sharing links on print or social media, turn the finished address into a scannable code with our QR Code Generator.

URL Decoder Online Free: Make Encoded Links Readable

Ever seen a link full of %20 and %3A? This url decoder online free translates those codes back into normal characters so you can read, check and edit them. It is handy for debugging analytics links, inspecting redirects and cleaning up addresses copied from emails or logs.

Encode URL Online in Three Simple Steps

You can encode url online without any technical knowledge:

Paste your text or link into the input box.
Select Encode to convert it, or Decode to reverse it.
Press Copy and paste the result into your browser, code or document.

The output updates as you type, so you do not need to press a separate convert button.

URL Percent Encoding Online: How It Works

URL percent encoding online simply means replacing unsafe characters with a percent sign followed by two hexadecimal digits. A space becomes %20, an ampersand becomes %26, and a letter like é becomes %C3%A9. Letters, numbers and the characters - _ . ~ are left unchanged. Here is an example of the result:

Input:  https://example.com/search?q=cats & dogs
Output: https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dcats%20%26%20dogs

This example encodes the whole string as a single value, which is what you want when a URL is passed inside another URL's parameter.

Decode URL String Online Without Errors

When you decode url string online, the tool reads each %XX code and restores the original character, including multi-byte UTF-8 text such as accents and symbols. If a string contains a broken code, for example a stray % with no digits after it, the tool will warn you instead of returning garbled output. Need a unique value to attach to your links? Generate one with the UUID Generator.

Tips for working with encoded URLs

Encode only the values in a query string, not the whole link, unless the URL is nested inside another URL.
Never decode a string twice, or characters like %2520 will turn into the wrong text.
A + sign often means a space in form data, while %20 always means a space.
Test the final link in your browser before publishing it.

Frequently asked questions

Is this url encoder and decoder really free? Yes. It is free, requires no registration, and has no usage limits.

Is my text uploaded anywhere? No. Everything is processed in your browser and nothing is sent to a server.

Why do URLs need encoding? URLs can only safely contain a limited set of characters. Encoding converts everything else into a format browsers and servers understand.

Does it support non-English characters? Yes. Text is converted using UTF-8, so accents, symbols and non-Latin letters are handled correctly.
