FAQ
Is there a limit on how many files I can merge?
There is no hard limit, but merging many large files may be slow due to browser memory constraints. For best performance, keep total file size under 200 MB.
Will there be a gap between merged files?
No silence is added between files. They are concatenated back-to-back. If you need silence between files, add a short silent MP3 between them.
Can I merge MP3 files with different bitrates?
Yes. The tool handles files with different bitrates and re-encodes the output at 192 kbps.
