Frequently asked questions
Can I join files with different formats or sample rates?
Yes — each file is decoded and combined into one consistent format (44.1kHz stereo MP3), so mismatched inputs still join correctly.
How many files can I join at once?
Up to 10 files per join, each up to 20MB.
Can I reorder the files before joining?
Yes — use the up/down arrows next to each file to set the join order before combining.
Is it free?
Yes, free with no account required, limited to a fair-use number of joins per hour.
