Combine your MP3 recordings in the right order, trim the edges, and download one MP3. Free, with no signup or added watermark.
Add two or more MP3 tracks to the joiner.
Select each file and use its up or down arrow. Confirm the visible order rather than assuming filenames or upload order form the sequence you want.
Choose Cut, adjust the handles, then Confirm cut to keep a clip’s useful range. Enable Crossfade into next clip for an optional short overlap; leave it off between spoken sections.
Preview the sequence, merge it in the browser, and save the final MP3.
Put spoken files in topic order, trim repeated greetings, and leave crossfade off so words do not overlap. Check each join before exporting. If a phone recording is M4A or OGG rather than MP3, use Audio Joiner instead.
Arrange the songs or excerpts and enable crossfade on the outgoing clip where blending helps. The overlap is up to 1.25 seconds, limited by neighboring clip lengths. There is no automatic beat matching or tempo synchronization.
Join an introduction, explanation, and examples into one listening file. Keep natural pauses in the clips. The resulting MP3 has no automatically generated chapter navigation, transcript, or playlist entries.
Merge several MP3 parts into a single deliverable and confirm the receiving platform’s size limit. Output uses 320 kbps, roughly 2.4 MB per minute before small headers. A joined file may be larger than expected when the originals use lower bitrates.
| Tool | Accepted input | Output | Best for |
|---|---|---|---|
| MP3 Joiner | MP3 only | MP3 | A focused MP3 merging workflow |
| Audio Joiner | Mixed audio formats | MP3, WAV, M4A, FLAC, OGG, AAC | Combining files delivered in different formats |
Use three MP3 files and keep the source copies. This creates a sequential recording rather than placing music underneath speech.
Import the MP3 introduction and both takes. Wait for the waveforms, then move the introduction to the top with the up control.
Select each clip, use Cut and Confirm cut to remove unwanted edges, and leave Crossfade into next clip off for spoken material. Preview the project to check order and pauses.
Choose Join MP3 Files. Play the downloaded file and confirm its length and order. If title, artist, or cover art matters, open the result in MP3 Tag Editor as a separate next step.
This focused page accepts MP3 files only and exports MP3. It supports 2–10 clips, including duplicates, and up to 30 minutes of rendered output. Use Audio Joiner for mixed formats or WAV output.
Each source is decoded and the final sequence is encoded as a new 320 kbps MP3. This enables trimming, effects and crossfades but is not a stream-copy merge. A higher bitrate cannot restore detail missing from the input.
Crossfade overlaps adjacent clips by up to 1.25 seconds, capped at half of either clip, so it shortens the total. It is not an independent backing-track layer, and there is no insert-silence button or adjustable crossfade curve.
No signup, payment or audio watermark is required. Local audio is processed in your browser; network imports and encoder downloads use network requests. Large files may exceed device memory. Download before closing and retain originals.
Check that it is an actual MP3, not a renamed M4A, WAV or protected file. Use Audio Joiner for other supported formats. A damaged MP3 can still fail browser decoding.
Check trimmed ranges and speed settings. Enabled crossfades subtract overlapping time from the total. Small codec-padding differences can also affect reported MP3 duration.
Disable crossfade between spoken clips. Retain a natural pause at the end of a take and preview the boundary. For music, try the short crossfade, but it cannot automatically match rhythm or perceived loudness.
Joining audio does not combine every source’s tags into a useful final description. Inspect the result in MP3 Tag Editor and set the final title or artwork there.
Yes. Arrange the tracks before rendering; the final MP3 follows the displayed sequence.
Yes. Every track has its own start and end controls.
Yes. Enable crossfade after a track to overlap it with the next track.
The current precise timeline renderer decodes the tracks and creates a new MP3 so trimming and crossfade can be applied consistently.
You can add up to 10 files in one browser project.
Use the Joiner for ordering separate files. Use MP3 Editor when your main task is to duplicate, trim and rearrange several passages inside one recording.
