Safe Web Links: The URL Encoder

Introduction

Have you ever copied a web address and noticed it’s filled with %20 or %3F? URLs can only contain a specific set of safe characters. Sending spaces, special symbols, or non-English characters in a web link without encoding them first is a recipe for a broken page.

What is this tool?

The URL Encoder (and Decoder) is a utility that translates unsafe characters into a web-safe format using percent-encoding. For example, it turns a space into %20. It can also reverse the process, turning an ugly, encoded URL back into a readable string.

Step-by-Step Guide on how to use it

  1. Select your mode: Encode or Decode.
  2. Paste the text or URL you want to process.
  3. Click the process button.
  4. Copy the safe URL to use in your application or email.

Practical Use Cases

  • Building Query Strings: Ensuring data sent via GET requests (like a search term) doesn’t break the URL.
  • Affiliate Marketing: Encoding complex tracking URLs before wrapping them in a redirect link.
  • Reading Logs: Decoding encoded URLs found in server logs to understand what the user was actually trying to access.

FAQ

What characters get encoded?

Everything except alphanumeric characters and a few safe symbols (-, _, ., ~). Characters like spaces, brackets, ampersands, and equals signs are all encoded.

Is URL encoding different from HTML encoding?

Yes. URL encoding (percent-encoding) is specifically for web addresses, whereas HTML encoding (like &) is used for displaying text safely inside a web page.
