Local video processing: your video stays in this browser. Export creates a newly encoded WebM video; it does not rename the original file.
Checking browser video export support…
MP4, WebM, Ogg video, or MOV up to 100 MB; maximum five minutes, 4,096 px per side, and 8 megapixels. The browser must decode the source.
90° and 270° exchange the video width and height. Export runs in real time at up to 30 fps and stops at 500 MB.

사용 방법
사용 방법
- Choose an MP4, WebM, Ogg video, or MOV file up to 100 MB.
- Select 90°, 180°, or 270° clockwise and review the swapped pixel dimensions where applicable.
- Rotate and re-encode the video in this browser, then preview and download the finished WebM file.
A real local video export
The page plays the selected file locally, draws its decoded frames onto a canvas at the selected orientation, and records that canvas stream. The download is a newly encoded WebM video with the MIME type reported by the browser; it is never a renamed source container.
Practical browser boundaries
Input is limited to 100 MB, five minutes, 4,096 pixels on either side, and 8 megapixels. Rotation runs at up to 30 fps in real time, so a five-minute source normally takes about five minutes to export. The page stops if its recorded output exceeds 500 MB. Canvas pixels, the source file, and encoded chunks remain in browser memory, so close other memory-heavy tabs before processing a large clip.
Codec and audio support
A current browser must decode the source and support canvas capture plus MediaRecorder. The output is WebM because native browser recording cannot reliably create MP4 everywhere. Chromium-based browsers usually carry a playable source audio track into the output; browsers that cannot expose that track still export the rotated video but report that limitation before processing.
자주 묻는 질문

Which direction do the choices rotate?
All choices rotate clockwise: 90° turns a landscape video upright when it was recorded sideways to the left, 180° turns it upside down, and 270° is a 90° counterclockwise turn.
Will 90° and 270° change the dimensions?
Yes. They exchange the decoded width and height. A 1920 × 1080 video becomes 1080 × 1920; 180° retains 1920 × 1080.
Why is the download WebM instead of MP4?
The browser records a fresh media stream and WebM is the broadly supported native recording container. The page uses the exact WebM MIME type the browser confirms before it begins.
Does the video leave my device?
No. Selection, decoding, frame rotation, recording, preview, and download occur in the browser. This page does not upload or retain video files.
