YAML Input

URL-Encoded Output

What is YAML URL Encoding?

YAML URL encoding converts a YAML string into a percent-encoded format that is safe to include in URLs, query parameters, and HTTP request bodies. Special characters like colons, spaces, newlines, and brackets are replaced with their percent-encoded equivalents (e.g., a space becomes %20).

According to RFC 3986, URLs may only contain a limited set of ASCII characters. When YAML data needs to be passed as a URL query parameter or stored in a URL, it must first be percent-encoded. This tool applies JavaScript's encodeURIComponent() to the entire YAML string, producing a safe encoded representation.

This tool uses JavaScript's native encodeURIComponent() function, which encodes all characters except: A–Z a–z 0–9 - _ . ! ~ * ' ( ). Colons, newlines, and other YAML-significant characters are safely encoded for URL transmission.

How to URL-Encode YAML

Follow these steps to URL-encode your YAML string using this tool.

Paste or Upload Your YAML

Paste your YAML content into the left panel, or click Upload to load a .yaml file. Click Sample to load an example. Example YAML:

name: John Doe
age: 30
roles:
  - admin
  - editor

Click Encode

Click the Encode button. The right panel instantly shows the URL-encoded output. Every special YAML character is safely percent-encoded.

Copy or Use the Output

Click Copy to copy the encoded string to your clipboard. Paste it into URLs, query strings, or API payloads wherever percent-encoded content is needed.

When You'd Use YAML URL Encoding

API Query Parameters

Pass YAML configuration data as a URL query parameter to REST APIs. URL-encoding ensures the YAML structure is safely transmitted without breaking URL syntax.

Webhook Payloads

Encode YAML data for inclusion in webhook URLs or form-encoded HTTP bodies where raw YAML would break the request format.

Configuration Sharing

Share YAML configurations via URL links by encoding them as query parameters. Recipients can decode and use the config directly in their tools.

CI/CD Pipeline Variables

Encode YAML snippets for safe storage in environment variables or pipeline parameters where special characters would cause parsing issues.

Frequently Asked Questions

What characters get encoded?

All characters outside the unreserved set defined in RFC 3986 are percent-encoded. For YAML, this includes colons (:), spaces, newlines, brackets, and quotes.

Is this the same as Base64 encoding?

No. URL encoding (percent encoding) replaces special characters with %XX hex sequences. Base64 encodes binary data into ASCII characters. For URLs, percent encoding is the correct approach.

Can I decode the output back to YAML?

Yes. Use our YAML URL Decode tool to convert the percent-encoded string back to the original YAML content.

Is my YAML data sent to a server?

No. All encoding happens entirely in your browser using JavaScript's encodeURIComponent(). Your YAML never leaves your device.

Does encoding validate the YAML?

No. This tool encodes any string as-is. It does not validate whether the input is valid YAML. Use our YAML Validator if you need validation before encoding.
