Merge Videos FAQs

Can I merge videos with different resolutions?
Yes. Videos with varying resolutions or aspect ratios will be automatically fitted and unified into a standard MP4 file.
Is there a limit on file size or number of clips?
There is no hard limit. Processing depends on your device memory. Merging 2 to 10 clips per batch provides optimal performance.
Are my video clips uploaded anywhere?
Never. All clips are merged locally on your computer or phone with zero cloud storage.
