Real MP4 (H.264) where your browser can encode it — Chrome, Edge and Safari — with WebM (VP9) as an automatic fallback elsewhere. Everything is transcoded on your device; nothing is uploaded.

Yes — everything is scaled onto the first clip's canvas automatically.
Merge Videos concatenates clips through the on-device pipeline: add any number of files, drag them into order, and the engine plays each through a common canvas and encoder to produce one seamless output — resolution is unified automatically to the first clip's size.
It's free, private and works right in your browser — no signup, no watermark.
