Questions
Anything else? Write to contact@doetra.com.
Is converting MOV to MP4 lossless?
Usually yes — when the video inside is compatible it is copied without re-encoding.
Can I convert several files at once?
One at a time; "Same edits on the next video" repeats your settings in one tap.
Is Doetra Video Studio really free?
Yes — every tool is free with no watermark, no signup and no file-size paywall. Your own device does the processing, so there is no server cost to pass on to you.
Are my videos uploaded anywhere?
No. Videos are opened, edited and exported entirely inside your browser. Nothing is sent to a server, which also makes it much faster than tools that make you upload first.
Can I combine several edits?
Yes — that is the idea. Drop your video once, stack edits like trim, resize for Reels, add text and fit under 16 MB, then export once. Every edit is applied in a single pass, so it is fast and loses less quality.
