frequently asked questions
will the aspect ratio change?
no. choosing a height scales the width automatically, so nothing is stretched.
can i make a video bigger?
yes, but upscaling does not add detail. it is best for matching a platform requirement.
is it free of watermarks?
yes. there is no watermark and no upload; ffmpeg runs in your browser.
