What Is Base64 Decoding?
Base64 decoding reverses Base64 encoding, converting a string of A-Z, a-z, 0-9, + and / (or their URL-safe equivalents) back into its original text. It is the tool to reach for whenever you have a Base64 string — from a JWT token, an API response, or an email header — and need to read what it actually contains.
This decoder automatically handles both standard and URL-safe Base64 input, so you don't need to know in advance which variant you're working with.

टिप्स
Remove Extra Whitespace First
If decoding fails, check for accidental line breaks or spaces copied along with the Base64 string.
Use This to Inspect JWT Payloads
JWT tokens are made of Base64-encoded segments — decode the middle segment to see the payload (note: this does not verify the signature).
