Base64 to Text Decoder

Base64 to Text decodes a Base64 string back to readable text with full UTF-8 support, and flags invalid input with a clear message. It is for developers inspecting encoded values from tokens, configs, or APIs.

Base64 is unreadable until decoded, and pasting it into a random site risks leaking data. Decoding locally reveals the text with the input kept private.

1. Paste the Base64 string you want to decode.
2. It is decoded back to text, with UTF-8 handled correctly.
3. If the input is not valid Base64, a clear message explains why.
4. Copy the decoded text.

• Base64-to-text decoding
• Full UTF-8 support
• Helpful invalid-input messages
• Decoded on your device

• Reading a Base64-encoded value from a config file
• Inspecting a decoded token payload
• Recovering text from a data URI
• Checking what an encoded API field contains

• Strip surrounding whitespace and line breaks if a paste fails to decode.
• Check whether the source used URL-safe Base64, which swaps two characters.
• If the result looks like gibberish, the original data was probably binary, not text.

• Pasting a string with stray spaces or line breaks, which can fail decoding.
• Confusing standard and URL-safe Base64, which use different characters.
• Expecting meaningful text when the data was binary, not text, before encoding.
