Frequently Asked Questions

How many files can I merge at once?+

There's no hard limit, but browser memory limits apply. Merging 10-20 files of reasonable size works well. Very large batches may require more time.

Can I merge files of different formats (MP3 + WAV)?+

Yes! You can mix different input formats. All files are decoded and re-encoded into your chosen output format during merging.

Will there be a gap between merged files?+

Files are joined seamlessly with no added gap. If you want a pause between files, use the Audio Trimmer to add silence, or use a DAW for advanced editing.

Can I reorder the files before merging?+

Yes — use the ↑ ↓ buttons on each file card to reorder them. Files are merged in the order shown from top to bottom.
