Frequently Asked Questions
What if the Base64 string is invalid? You will see an error message. Common issues include missing padding (= signs) or non-Base64 characters in the input.
Can it decode binary files? This decoder outputs text. For binary data (images, PDFs), the output will appear as garbled characters. Use a file-based decoder instead.
