Converting between lossless formats preserves perfect quality. When converting to lossy formats, our optimized encoding minimizes any audible difference. You can adjust bitrate to control quality vs. file size.
We preserve ID3 tags, album art, and metadata when both AAC and RAW Audio support them. Some metadata may not transfer between incompatible formats.
Pro users can batch convert multiple audio files simultaneously. Free users convert one file at a time with up to 5 free conversions per day.
We support all standard sample rates from 8kHz (voice) up to 192kHz (studio quality). The default preserves your source file's sample rate.
Yes. Our audio converter handles music, podcasts, voice memos, and audiobook files. For podcasts, we recommend MP3 at 128-192kbps for the best balance of quality and file size.
