FAQ
- Does it validate input?
- Yes, it checks for valid characters and handles spaces or commas in Hex strings.
- Does it handle URL-safe Base64 (the kind using - and _)?
- The converter is built around standard Base64 (+ and /), so for URL-safe input you'll need to swap - back to + and _ back to / before pasting it in to get an accurate result.
