Frequently Asked Questions

What is URL encoding (percent-encoding)?

URL encoding replaces unsafe or reserved characters with a percent sign followed by two hex digits (e.g. a space becomes %20). This ensures URLs are transmitted correctly over the internet.

Which characters are percent-encoded?

Characters outside the unreserved set (A-Z, a-z, 0-9, "-", "_", ".", "~") are encoded. Reserved characters like &, =, ?, and # are also encoded when they appear inside query values.

When should I URL-encode a string?

URL-encode any value you place in a query parameter, path segment, or fragment that may contain spaces, special characters, or non-ASCII text. This prevents broken links and ambiguous parsing.

Is my data sent to a server?

No. All encoding and decoding happens locally in your browser. Your data never leaves your device.
