What is URL Encoding?
URL encoding, also known as percent-encoding, converts unsafe characters into a format that can safely travel across the internet. Characters like spaces, ampersands (&), hashtags (#), and question marks (?) can break URLs if they are not properly encoded.
For example, a space becomes %20, while an ampersand becomes %26. This ensures browsers and web servers correctly understand your links, query strings, and API parameters.
Our free URL Encoder & Decoder tool is useful for developers, SEO experts, digital marketers, and anyone working with browser-safe URLs, redirect links, tracking URLs, or API requests.

URL Formatting FAQs
What is "Percent-Encoding"?
It's a way of representing special characters using a percent sign followed by two hex digits. It ensures data is parsed correctly by web servers.
Why do some URLs fail without encoding?
Characters like spaces or ampersands have special meanings in URLs. If they aren't encoded, the server might break the link or lose your data.
Is this tool safe for sensitive URLs?
Yes. Since all processing happens in your browser, the URL you are encoding never travels to our database or server logs.
Can I decode any URL?
Most URLs can be decoded easily. However, if a URL is actually encrypted or hashed (like base64), it requires a different tool.
