Crop a video into a circle or rounded square — great for avatars, video notes and overlays. Everything runs in your browser; nothing is uploaded.
The area outside the shape is filled with your background colour — browsers can't record true transparency. Rendering runs in real time.
The Circle Video tool crops a video into a circle or rounded square and exports it — right in your browser, with no upload, no watermark, and no software to install.
Rounded video shapes look polished as profile avatars, chat video notes, and picture-in-picture overlays. Drop in a clip, pick the shape, size and background, and the tool re-frames your footage into the shape and re-encodes it locally. People use it to:
Because browsers can't reliably record transparency, the space around the shape is filled with a background colour you choose. Everything happens on your device, so your footage stays private.
No. The video is cropped and re-encoded entirely in your browser, so it never leaves your device.
No — browsers can't reliably record video with transparency, so the area outside the circle is filled with a background colour you choose (black or white are common). The circle itself shows your footage.
Circular and rounded videos are popular for profile avatars, chat video notes, picture-in-picture overlays, and social clips where a soft, rounded shape looks cleaner than a hard rectangle.
Browsers re-encode video in real time through the MediaRecorder API, so a 30-second clip takes roughly 30 seconds. That is the trade-off for processing locally with no upload.
WebM (VP9 or VP8 with Opus audio) works everywhere in modern browsers. On browsers that support MP4 recording, mainly Safari, an MP4 option appears too.
