Frequently Asked Questions

What is URL encoding?

URL encoding (percent encoding) converts special characters in strings into a format safe for URLs. For example, spaces become %20, and non-ASCII characters are converted to percent-encoded sequences.

How do I encode or decode a URL?

Paste your text or URL into the input area and select encode or decode. The tool instantly converts the string, showing the URL-safe encoded version or the decoded original text.

When do I need URL encoding?

When passing user input, special characters, or non-ASCII text as URL query parameters. For example, a search query with spaces or symbols needs encoding to work correctly in a URL.

What is the difference between URL encoding and Base64?

URL encoding preserves the readability of a string by only encoding special characters (percent encoding). Base64 encodes all binary data into a limited ASCII character set, which is not human-readable.

Is this tool free?

Yes, ToolDock's URL encoder/decoder is completely free, requires no signup, and runs entirely in your browser.
