Join MP3 files in sequence—not on top of each other
An MP3 merger, MP3 joiner or MP3 combiner places separate files end to end. The finished MP3 plays from the first clip through the last as one continuous track.
Prepare every MP3 before you join it
Arrange the clips, remove unwanted edges and listen across each transition before creating the finished MP3.
Choose Add next audio to append another MP3 to the selected track. The visible timeline becomes the running order of the finished file.
What you can do- Append clips to one track
- Build a sequence of up to 48 clips
- Move a clip when the order changes
Best for turning separate MP3s into one clear first-to-last sequence.
See the MP3 running order before export
Shorten a false start, long ending or silent edge on an individual MP3 before the complete timeline is exported.
What you can do- Trim one clip without changing the original
- Remove repeated words or dead space
- Close an accidental gap
Best for making adjacent recordings meet at the right moment.
Select an MP3 and adjust its level when files recorded or mastered at different times do not sound equally loud.
What you can do- Adjust one clip at a time
- Listen from before the join
- Keep speech and music at a comfortable level
Best for avoiding a distracting volume jump between MP3s.
Set fade-in or fade-out on an individual clip, then play across the join. Automatic crossfade is not applied.
What you can do- Soften an abrupt entrance
- Create a cleaner ending
- Check every transition before export
Best for keeping the result intentional without hiding the join from you.

How to merge MP3 files online
Start with the first file on this page, then add every remaining MP3 inside Audio Editor without returning to the upload screen.
Upload the first MP3
Choose the MP3 that should play first. It opens directly on a new Audio Editor timeline.
Add the remaining MP3s
Choose Add next audio inside the editor. Each new MP3 is placed after the previous clip on the same track.
Arrange, trim and preview
Check the running order, remove unwanted clip edges and listen from before each join. Adjust a clip if its volume is noticeably different.
Export one MP3
Keep MP3 selected, choose Export Audio and download the complete sequence as one 192 kbps MP3.
What do you want to combine into one MP3?
Choose a practical workflow that fits the current 60-minute project limit.
Share several voice takes as one MP3
When a narration, interview answer or voice note was recorded in short takes, one ordered MP3 is easier for someone else to open and follow.

What happens when you export the merged MP3?
The editor creates a new listening file. Your source MP3s remain unchanged on your device.
192kbps MP3
One practical file for listening and sharing
The complete timeline is rendered into one 192 kbps MP3, regardless of the bitrates used by the individual source files.
A new encode, not a byte-for-byte join
The MP3 sources are decoded and encoded again. Finish your trimming and volume changes before export to avoid unnecessary additional compression passes.
Bitrate does not automatically match loudness
Files from different recorders or music releases may still sound louder or quieter. Preview the joins and adjust individual clips when needed.

Merge MP3 files without handing them over
Your recordings are decoded, arranged and rendered on your device. You can begin without installing software or creating an account.
- Processed in your browser
- MP3 files used in the merger are not sent to an AudioMuse processing server.
- Original MP3s stay unchanged
- Timeline edits and export create a new file without overwriting the sources on your device.
- Local projects are optional
- Library projects stay in this browser; they are not account-linked, cross-device storage or a permanent backup.
Online MP3 Merger FAQs
Playback order, trimming, MP3 quality, file limits and browser privacy.
How do I merge MP3 files online?
Upload the MP3 that should play first. In Audio Editor, choose Add next audio to append each remaining MP3 to the same track. Arrange the clips, preview the joins, then export one combined MP3.
Can I merge two MP3 files into one?
Yes. Upload the first MP3 here, then use Add next audio in the editor to add the second. The second clip begins after the first one ends, and both are rendered into one MP3 when you export.
Can I change the order before exporting?
Yes. Add files in the intended order or move a clip on the timeline before export. Play from before a join to confirm the complete running order.
Can I cut and merge MP3 files in the same editor?
Yes. You can trim the beginning or end of an individual clip, close an unwanted gap and then export the complete sequence. Automatic crossfade is not applied, so fades and joins remain under your control.
Does merging MP3 files reduce quality?
The editor decodes the source MP3s and creates a new 192 kbps MP3. That means the result is re-encoded rather than joined byte for byte. Finish trimming and volume changes before exporting, and keep the original files.
Can MP3 files with different bitrates be merged?
Yes. Source files can use different MP3 bitrates because the complete timeline is rendered into one 192 kbps MP3. Bitrate conversion does not automatically match loudness, so preview files recorded or mastered at different levels.

Is this MP3 merger free?
Yes. You can join and export MP3 files without creating an account. The current editor supports projects with up to 48 clips and a combined timeline of up to 60 minutes.
Are my MP3 files uploaded to a server?
No. MP3 files used in the editor are decoded, arranged and rendered in your browser. Optional Library projects stay in this browser and are not synced to an account or another device.
How many MP3 files can I combine?

What is the difference between MP3 Merger and Audio Mix?
MP3 Merger places clips end to end so they play one after another. Audio Mix puts sounds on separate tracks so voice, music and effects can overlap and play at the same time.
