Can I convert audio files larger than the upload limit?

The tool has file size restrictions for free use; larger files may need to be split or converted using a desktop encoder.

Does the Base64 output include a data URI prefix?

The converter generates a raw Base64 string; you must add the appropriate data URI prefix (such as "data:audio/mp3;base64,") when embedding in HTML.

Can I convert audio formats other than MP3?

Yes, the tool supports WAV, OGG, M4A, FLAC, and AAC in addition to MP3, allowing flexibility for different source files.

Is the converted Base64 string safe to store in databases or JSON payloads?

Yes, the Base64 string is text-only and can be safely stored or transmitted in text-based systems, databases, or JSON payloads without corruption.
