FAQ
What is Base64 used for?
Base64 is commonly used to safely transport binary data as text (e.g., data URIs, basic auth headers, email attachments).
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it.
Why does decoding fail sometimes?
Most failures come from invalid characters, missing padding (=), or copying a URL-safe Base64 variant. Try cleaning whitespace or using the correct variant.
