URLs can only contain certain characters from the ASCII set.When a URL contains special characters or spaces, they must be converted into a safe "percent-encoded" format.Our Online URL Encoder / Decoder makes this process seamless for developers and SEOs.

When Should You Use This Tool ?

• Encoding : Use this when you are creating URL parameters (query strings) that contain spaces or symbols (e.g., "?query=hello world" should be "?query=hello%20world").
• Decoding: Use this when you have a messy URL and you want to see the original, human-readable text.

Key Benefits

Incorrectly encoded URLs can lead to 404 errors or broken links.This tool ensures your tracking links, social share buttons, and API calls are formatted strictly according to RFC 3986 standards.

Privacy First

Like all our utilities, encoding and decoding happens locally.Your URLs—which might contain sensitive data or tokens—are never transmitted to our servers.
