FAQ

What is percent-encoding?
Characters that are unsafe in URLs are replaced with a % followed by their hex code, so spaces and symbols survive in query strings.
Does it handle UTF-8 characters?
Yes — non-ASCII characters are encoded correctly using their UTF-8 byte sequences.
Is my data sent to a server?
No. Encoding and decoding run entirely in your browser.
