MP3 tips
🎵
M4A is Apple's default for voice memos and iTunes. MP3 plays on virtually every device, player, and car stereo.
🎚️
Keep the bitrate at or below your source. M4A at 256 kbps → MP3 at 256 kbps preserves the quality without bloating the file.
⚠️
Converting between two lossy formats loses a little quality each time. Convert from the original once rather than repeatedly.
🔒
Voice memos and private recordings are converted in your browser — they never upload anywhere.
