URL Encoder and Decoder

Introduction

The URL Encoder and Decoder converts ordinary text into URL-safe percent encoding and turns encoded text back into readable form. It is a practical helper for query strings, redirect URLs, API testing, and debugging links.

About this url encoder tool

URLs reserve certain characters for structure, including question marks, ampersands, slashes, equals signs, and spaces. When those characters are part of a value rather than part of the URL syntax, encoding prevents the browser or server from reading the link incorrectly.

How this tool works

Paste the value you want to encode or decode and choose the direction. Encoding replaces unsafe characters with percent sequences; decoding reverses valid sequences. If an encoded string is malformed, the tool shows an error rather than guessing at the intended text.

1. Paste the text or URL component you want to convert.
2. Choose encode or decode.
3. Copy the converted output for use in links, query strings, or debugging.

When to use this tool

Use it when building links with query parameters, checking webhook payloads, debugging redirects, or preparing values for campaign URLs. Usually encode individual components, not an entire URL, so reserved characters that define the URL structure keep working.

Good to know

• Use this for URL components such as query parameters, not for validating whether a full URL is safe.
• Malformed encoded text may not decode until invalid percent sequences are fixed.
