Audio Merger
Combine multiple audio clips into one file, in the order you choose. Runs in your browser via ffmpeg.wasm.
Stitching together voice memos, podcast segments, or music clips into one file normally means opening a full audio editor. This tool lets you add multiple clips, reorder them, and merge them into a single file using FFmpeg running locally via WebAssembly - no upload, no editing software. Clips in the same format concatenate cleanly and fastest; mixing formats can still work but may need re-encoding, which takes a little longer.

Common questions
Do the clips need to match?
For best results, use clips with the same format (e.g. all MP3). Mixed formats may fail or produce sync issues.
Does it upload my audio?
No - merging runs locally with WebAssembly. Nothing leaves your browser.
Is there a limit on how many clips I can merge?
No hard limit - merge as many clips as your browser's memory allows.
Will the merged file re-encode my audio?
Matching formats can often be concatenated with minimal re-encoding; mismatched formats require a full re-encode to combine cleanly.
