URL Encoder / Decoder: Complete Guide for Safe and SEO-Friendly URLs
A URL Encoder / Decoder is an essential tool for developers, SEO experts, and digital marketers. It helps convert URLs into a format that can be safely transmitted over the internet and also decode them back into readable text.
In this detailed, SEO-optimized guide, you’ll learn what URL encoding is, how encoding and decoding work, and why this tool is important for websites and applications.
What is URL Encoding?
URL Encoding (also known as percent encoding) is the process of converting special characters in a URL into a format that can be safely sent over the internet.
Some characters (like spaces, symbols, and non-ASCII text) are not allowed in URLs, so they are replaced with a % followed by a hexadecimal value.
Example:
| Character | Encoded Value |
|---|---|
| Space | %20 |
| ! | %21 |
| @ | %40 |
| # | %23 |
👉 Example:
Original URL:
https://example.com/search?query=hello world
Encoded URL:
https://example.com/search?query=hello%20world
What is URL Decoding?
URL Decoding is the reverse process. It converts encoded characters back into their original readable form.
👉 Example:
hello%20world → hello world
