Frequently Asked Questions

Can I merge videos with different resolutions or formats?

Will there be a watermark on the merged video?

Are my personal videos uploaded to the internet?

What is the difference between Ultra-Fast and Max Quality modes?

"Ultra-Fast" attempts a direct stream copy, which joins files instantly without re-encoding. "Max Quality" re-encodes the entire sequence to H.264/AAC, guaranteeing maximum compatibility across all devices and fixing mismatched formats.

Is there a file size limit for merging?

Because processing happens in your browser rather than the cloud, there are no artificial server limits. You can safely merge gigabytes of data, limited only by your computer's available RAM.
