Learn the best URL and base64 utilities for debugging
Encoded values show up all the time when working with web apps, APIs, and auth flows. The ability to decode them quickly is a real productivity win.
URL encoding protects special characters in routes, query strings, and form data. When a value fails to round-trip, a quick encode/decode check often reveals the problem immediately.
Base64 is useful for inspecting tokens and payloads, but it is not encryption. Use it to decode and inspect data structure, not to protect secrets.
Treat these tools as a debugging aid, not a fix for broken auth or unsafe data handling.
