appkiro.comOutput produces a data URL with the matching MIME.
Encode any audio file — MP3, WAV, OGG, M4A, FLAC, Opus — into Base64. Useful for pipelines that demand text-only payloads.
Embedding sounds inline, sharing audio fixtures in chat, or creating single-file HTML demos that bundle their own audio.
For pure-text payloads use the Text to Base64 tool.
Does the file leave my browser?
No. Encoding runs in your tab — nothing is uploaded.
Is there a file size limit?
Practical limits depend on browser memory; encoding is comfortable up to ~50 MB.
What MIME is used?
The browser-detected MIME for the chosen file (e.g. audio/wav).
