URL Encoder/Decoder

URLs are strict about which characters they accept. Spaces, slashes, and non-ASCII letters all require transformation before they can travel safely across the web. A URL encoder handles that transformation instantly and accurately.

What Is a URL Encoder?

A URL encoder replaces unsafe characters with a percent sign followed by two hexadecimal digits. For example, a space becomes %20 and an ampersand becomes %26. This guarantees that servers, browsers, and APIs parse the URL structure correctly rather than misinterpreting a character as a delimiter.

Use Cases

• UTM campaign links – Encode spaces and special characters in tracking parameters.
• REST API calls – Safely pass user input as path or query variables.
• SEO canonical tags – Ensure non-ASCII URLs point to valid encoded equivalents.
• File downloads – Encode filenames in Content-Disposition headers.

How to Use Our URL Encoder

1. Paste the raw string or URL component you need to encode.
2. Select full URL mode if you want to preserve protocol and domain segments.
3. Copy the encoded result to your clipboard.
4. Use the decoder tab to reverse the process when inspecting incoming requests.

Tips for Maximum Impact

• Only encode the query or path segments, not the entire protocol string, unless necessary.
• Watch for double encoding when passing data through multiple systems.
• Use UTF-8 as the character set for modern web compatibility.
• Always encode user-generated input before embedding it in URLs.
