Frequently Asked Questions

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data as ASCII text. It's commonly used for encoding data in emails, URLs, and data URIs.

Will it handle invalid input?

If the input is not valid Base64, an error message will be shown. Make sure your input only contains valid Base64 characters.

What if I need to encode too?

Use our Base64 Encoder/Decoder tool at /dev/base64-encode for both encoding and decoding.
