Frequently Asked Questions
Q: What is Base64 decoding?
A: Base64 decoding converts Base64 encoded text back to its original form. It's the reverse process of Base64 encoding.
Q: Why am I getting an error?
A: Make sure your input is valid Base64. Base64 uses only A-Z, a-z, 0-9, +, /, and = for padding. Invalid characters will cause errors.
Q: Can I decode any Base64 text?
A: Yes! This decoder works with any valid Base64 encoded text, regardless of what the original content was (text, images, files, etc.).

Frequently Asked Questions
Why does my Base64 decoded output look like gibberish?
The decoded data might be binary rather than text. Try the Base64 to Image tool if the source data was an image, or ensure the Base64 was originally encoded from text.
What does "invalid Base64" mean?
Base64 uses only A-Z, a-z, 0-9, +, /, and = for padding. Any other character makes the string invalid. URL-safe Base64 also allows - and _.
Does the decoder handle multiline Base64 strings?
Yes. Base64 is sometimes split into 76-character lines. The tool handles both single-line and multiline Base64 correctly.
Can I decode an image from Base64?
For Base64-encoded images, use the "Base64 to Image" tool which renders the image directly from the data URI.
