Frequently asked questions

Which bitrate should I choose?
Voice and interviews: 128 kbps is plenty and keeps files small. Music: 192 kbps is transparent for most listeners, 320 kbps is the archival-safe ceiling.
Why is my preview only 30 seconds?
The free preview is a watermarked 30-second sample so you can verify the conversion. The paid file is the complete recording.
Does converting from MP3 to MP3 lose quality?
Yes, re-encoding any lossy format compounds loss slightly. If your source is already MP3 and the platform accepts it, upload as-is and skip this tool.
Are album art and title tags preserved?
Basic metadata is re-created from the source where available; embedded cover art is dropped in v1 (stated here so you are never surprised).

When this tool is not the right choice

Your file is already MP3 and the platform accepts MP3.
Upload it directly — re-encoding only degrades quality.
You need lossless delivery.
Keep FLAC/WAV — MP3 is lossy by definition; no tool can make it lossless.
