The corners are filled with the background colour, since video cannot be transparent. Processing plays the clip through once, so it takes about as long as the video.
Heads up: everything runs on your device, with nothing uploaded. Large or long videos can use a lot of memory and may slow down or even crash your browser tab, so keep this tab open and your device awake while it works. The Quick engine rounds with no download and exports WebM; the ffmpeg engine downloads about 31 MB the first time and exports MP4. Since video can’t be transparent, the corners are filled with your background colour.
Round Video Corners adds smoothly rounded corners to a video entirely in your browser with nothing uploaded. Choose how round the corners are and the background colour they sit on, since video cannot be transparent, and the original audio is kept. The clip is processed as it plays and saved as a WebM video, ready for social posts or websites.
Frequently asked questions
Is my video uploaded?
No. The video is processed entirely in your browser on your own device, so it never leaves your computer or phone.
Can the rounded corners be transparent?
Standard video files cannot store transparency, so the corners are filled with the background colour you pick. Choose the colour of the page or app where the video will sit and the rounding blends right in.
How long does it take?
The clip is processed as it plays through once, so it takes roughly as long as the video itself. A one minute clip takes about one minute.
Does it keep the sound?
Yes, the original audio is included in the exported file in browsers that allow it, such as Chrome and Edge.
Which browser and format?
The Quick engine works best in Chrome or Edge and saves a WebM video with no download. The ffmpeg engine downloads a built-in engine (about 31 MB) the first time and saves an MP4, which plays almost everywhere. Pick whichever you prefer.
