Frequently Asked Questions
What is URL encoding?
URL encoding converts special characters into percent-encoded format (e.g., space becomes %20) so URLs can be safely transmitted over the internet.
When should I use Component vs Full URI?
Use Component encoding (encodeURIComponent) for query parameter values. Use Full URI (encodeURI) for encoding a complete URL while preserving structure like /, :, ?.
What characters get encoded?
URL encoding replaces characters like spaces, symbols (!, @, #, $, etc.), and non-ASCII characters with their percent-encoded equivalents (%20, %21, etc.).
Is my data safe?
Yes. All encoding and decoding happens client-side in your browser. No data is sent to any server.
Can I decode any URL-encoded string?
Yes. The decoder handles both standard URI encoding and component encoding, and will attempt to recover from malformed input.
