What to check before exporting
Merge is sequential concatenation. It does not overlay background music, automatically remove silence at joins or crossfade the recordings. Mix Audio is the separate operation for sounds that should play at the same time.
Choose a compatible output profile and review the source streams, selected range and final settings. Processing uses structured controls, and incompatible combinations are rejected before queueing. Download the requested result when final validation completes.
A real workspace. A result you can inspect.
This actual product screenshot shows source playback, range selection, an uploaded-audio area and encoding settings. It illustrates the shared converter; your operation opens its own relevant controls after inspection.
A processed preview creates a separate short task. It covers the first ten seconds of your range at up to 360p in a compatible format. Image and subtitle exports still need inspection of the requested final download.

Questions about this workflow
Can I join files with different sample rates?
Re-encoding can bring supported sources to a common audio configuration. Copy mode requires compatible stream parameters and will reject incompatible combinations.
Can I close the tab while processing?
Yes. Submitted conversion tasks run in the background. Return to your account to check progress and download results before the retention period ends.
What are the upload and storage limits?
Current source limits are 2 GiB and two hours per file. Files have a 72-hour retention period; task, collection and resource limits also apply. The workspace shows the applicable limits. Free and Pro currently share feature access.
