Play clips back to back, leave a short pause, or let one song crossfade into the next.
No Quality Loss
When your MP3s already match, Smart mode joins them without re-encoding, so the result sounds exactly like the originals.
Six Output Formats
Save one MP3, M4A, WAV, FLAC, OGG or Opus file, at up to 320 kbps.

Resources
Learn more about merging audio with Free Merge MP3
Is Free Merge MP3 really free?
Yes. Merging, trimming, crossfades, tags and every output format are free. There is no paid export, no watermark and no account.
How do I merge MP3 files into one?
Click Add Files, drag the songs into order, pick MP3 as the output and click Merge audio. You get one new file and your originals stay untouched.
Will merging reduce the audio quality?
Not when the files match and you join them straight. Smart mode then copies the audio without re-encoding. Trims, crossfades, fades or loudness changes need an encode, so choose a high bitrate such as 320 kbps.
How many files can I merge at once?
Each merge takes from 2 to 200 clips.
Can I merge WAV, FLAC, M4A and MP3 together?
Yes. Mixed formats can sit in the same list. The app decodes them and saves the single output format you choose. It can also read the audio track from MP4, MOV and WebM files.
Can I add a pause or a crossfade between songs?
Yes. Choose a direct join, a silence gap of up to 30 seconds, or a crossfade between every clip.
Does it upload my audio?
No. Everything happens on your PC. Nothing is sent to an online converter.
Can it download from YouTube or burn a CD?
No. Free Merge MP3 joins audio files you already have. It does not download online videos, record, or burn discs.
Which Windows versions are supported?
Windows 11 and Windows 10, 64-bit. Setup offers Microsoft .NET Desktop Runtime 8 if your PC needs it. There is no Mac version.
