Base64 to Text

About this tool

Decode a Base64 string back into text. Leading and trailing whitespace is ignored and the decoded bytes are read as UTF-8, so accented characters and emoji come back correctly. It uses the standard Base64 alphabet. Decoding runs in your browser as you type. If the string is not valid Base64, or the decoded bytes are not valid UTF-8 text (for example a binary file), you will see an "Invalid Base64 input" warning instead.

How to use it

1. Paste the Base64 string.
2. Read the decoded text.
3. Copy it if needed.

Example

SGVsbG8=

Hello

Common problems

"Invalid Base64 input"

The string may contain characters outside the Base64 alphabet, be truncated, or be URL-safe Base64 (with - and _). Change - to + and _ to / and try again.

Garbled or no output for binary data

Only text can be shown. Data that is not UTF-8 text, such as an image or archive, cannot be displayed here.

Line breaks inside the string

Remove stray characters or quotes around the string if decoding fails.
