Rotate a sideways or upside-down video in your browser — lossless and instant. Nothing is uploaded.
A free online tool for the phone video that plays sideways or the clip that came in upside down — no editor to install, nothing uploaded. Rotating by 90°, 180° or 270° doesn't touch the video data at all: only the MP4 rotation metadata is rewritten, so there is no re-encoding, no quality loss, and even a long video finishes in seconds. The preview shows the new orientation before you save. Flipping (mirror left-right or upside down) has to process every frame, so it re-encodes to H.264 at a high-quality setting. Output is WebM if the source is WebM/MKV and MP4 otherwise, playable on iPhone, Android, PC and every social platform. The key difference from typical online rotators: your video never leaves your device. Everything runs locally via WebCodecs, so there is no upload wait, size cap or watermark. Audio is carried over untouched. A recent Chrome or Edge is recommended.
How to use
- Drop in a video file (MP4, MOV, WebM…).
- Choose a rotation (90°/180°/270°) and optionally a flip — the preview updates instantly.
- Press “Apply & save”, then download the video.
FAQ
Is my video uploaded?
No. Loading, rotating and exporting all happen inside your browser on your device — nothing is sent to or stored on a server. That's why there is no upload wait and no size limit.
Does rotating lower the quality?
Not for rotation (90°/180°/270°). The video data isn't re-encoded; only the MP4 'display rotated' flag is rewritten, so quality is identical and long videos finish in seconds. Flipping processes every frame and re-encodes at a high-quality setting — the difference is normally invisible.
Some player still shows the old orientation.
A few old players and apps ignore rotation metadata. Common devices — iPhone, Android, Windows, Mac and social platforms — honor it. If you hit one that doesn't, use a setting that processes frames (any flip) so the orientation is baked into the pixels.
When would I flip a video?
Mirror (left-right) fixes webcam or selfie footage that plays as a mirror image with unreadable text. Upside down is for a camera that was mounted inverted. Flips process frames, so they re-encode.
Which formats are supported, and what is the output?
Input: MP4, MOV, WebM, MKV and other formats your browser can read. Output: WebM if the source is WebM/MKV, otherwise MP4 — with the original codec for rotation-only, or H.264 (WebM/VP9 in browsers that can't encode H.264) when flipping. Audio is carried over.
