Frequently asked questions
Can I reorder the files after adding them?
Yes — drag any file in the list to change the join order before merging.
What does the crossfade do?
It fades the end of one clip into the start of the next over the duration you set, instead of an abrupt cut.
How many files can I join at once?
There's no fixed limit — add as many as you need, though very large batches take longer to process.
Does this upload my files?
No — everything is decoded, merged and re-encoded locally in your browser.
