Is Base64 encryption?

No. Base64 changes how bytes are represented and offers no confidentiality. Anyone can decode it without a key.

Can I decode a file from a data URI?

Yes. File mode accepts Base64 data URIs and detects PNG, JPEG, GIF, WebP, PDF, ZIP, and UTF-8 plain text. Unrecognized binary data downloads as a .bin file.

Are missing padding and line breaks accepted?

Yes. Decoding accepts whitespace and missing padding, while rejecting invalid characters, malformed padding, and nonzero unused padding bits. Choose the matching standard or URL-safe alphabet.
