Frequently asked questions

What is Base64 used for?

It's a way to represent binary or text data using only 64 printable characters — commonly used in emails, data URLs, and API payloads.

Why did decoding fail?

Make sure the input is valid Base64 — it should only contain letters, numbers, +, / and = padding.
