The video rotator is for the very common problem of a clip that records sideways or upside-down because the phone's rotation lock was on, or because a metadata flag was dropped during an upload. Instead of re-shooting, you can rotate the video to the correct orientation in your browser.
You can pick 90 degrees clockwise, 180 degrees, or 270 degrees (90 counter-clockwise). A live preview shows how the rotated frame will look, so you can confirm the output orientation before committing to a full re-encode.
Processing runs locally via WebCodecs. The output is a standard MP4 that plays everywhere — no more browsers or players rendering your video on its side. The original file is never uploaded.
Video Rotator — Frequently Asked Questions
Why does my video play sideways on my computer but not my phone?
Phones store a rotation flag in the video's metadata instead of rotating the actual pixels. Some players and editors (Windows Media Player, older Chrome versions, most social uploads) ignore the flag and show the clip on its side. Rotating the pixels permanently fixes playback everywhere.
How do I rotate a video by 90 degrees?
Drop your clip, pick '90° clockwise' (or counter-clockwise), and hit Rotate. The preview updates immediately so you can confirm the orientation before the full re-encode runs. Output is MP4 that plays on every device.
Does rotation reduce video quality?
A 90/180/270 rotation is a lossless pixel operation in content terms, but the video is re-encoded during export, which costs a small amount of fidelity. Using the High or Ultra preset keeps the result visually indistinguishable from the source on any normal screen.
What video formats can I rotate?
Any MP4, WebM, MOV, or MKV the browser can decode — that covers iPhone clips, Android recordings, GoPro footage, and most drone camera output. The rotated result is always MP4 for maximum compatibility.
Can I flip a video horizontally or vertically instead of rotating?
This tool focuses on 90/180/270 rotations. A dedicated mirror/flip feature is on the roadmap — ping us if you need it prioritized.
Is the video uploaded to a server?
No. Rotation happens entirely in your browser with WebCodecs. Your file stays on your device.
