Before you write about a decoding problem

• Check the string was copied completely — truncated Base64 is the most common issue.
• JWT tokens and URL parameters use Base64URL; our decoders handle both alphabets automatically.
• If decoded output looks like garbage, it may be a binary file — try Base64 to File.

Please do not include real production secrets, tokens, or credentials in emails — a description of the problem and, if needed, a sanitized example is enough.
