FLAC (.flac) · Max 20 MB
Gmail, Outlook, and Yahoo all cap attachments at 25MB. A single FLAC file often exceeds that within minutes of audio. Converting to MP3 at 128kbps keeps file sizes well under the limit.
For voice recordings and meetings, 128kbps mono is plenty. For music, 192kbps stereo sounds great and stays small. AudioUtils converts in your browser — no upload needed, no file touching anyone's server.
Drop your file, convert, download, attach. The whole process takes seconds. No signup, no email address required, no watermarks.
Frequently Asked Questions
What MP3 bitrate should I use for FLAC conversion?
320kbps for the best quality, 256kbps for a great balance, 192kbps if storage is tight. Avoid going below 192kbps — the quality drop becomes noticeable.
How much smaller will the MP3 be?
Dramatically smaller. A 30MB FLAC file becomes roughly 5-7MB as MP3 at 320kbps. That's a 75-80% size reduction.
Will the conversion preserve metadata?
The converter preserves basic metadata like title, artist, and album when possible. Cover art may not transfer in all cases.
Can I batch convert multiple FLAC files?
Free users can convert one file at a time. Pro users get batch conversion support for processing entire albums or libraries at once.
