Rotate Video

Rotate or flip a video — and make the fix actually stick

You filmed something on your phone, turned it sideways for a better angle, and now it plays sideways everywhere you upload it. Or you need a mirror image of a clip, or the whole shot is upside down. Rotating a video sounds trivial, but the reason it so often doesn't stick is a hidden metadata flag — and this free online tool handles that flag for you, so the rotation is baked into the actual pixels and the result is upright in every player, every editor and every platform. Upload an MP4, MOV, M4V, WebM, MKV or AVI, pick one operation, and download a clean H.264 MP4. No app to install, no watermark, no account.

The five operations

One tool covers both rotation and flipping — just choose the operation that matches what you need:

Rotating and flipping are different operations: a rotation turns the whole frame around its centre, while a flip produces a mirror image. Flipping horizontally is the one most people mean by "mirror a video" — handy for fixing footage from a selfie or webcam that records you back-to-front, so on-screen text reads the right way round.

Why "sideways" phone videos happen — and the metadata gotcha

Phones almost always record their sensor in one fixed orientation and then add a rotation flag to the file's metadata that says, in effect, "rotate me 90° on playback." Some players and platforms read that flag and rotate the picture; others ignore it and show the raw, sideways frame. That is exactly why the same clip can look upright in your phone's gallery but sideways on a website, in a video editor, or after you upload it.

This tool fixes that at the source. It bakes the rotation into the pixels and then clears the container rotation flag (rotate=0) so no player can rotate the video a second time. Without that step you can get the dreaded double-rotation, where a clip you just "fixed" comes out sideways the other way. Clearing the flag is the small, high-signal detail that makes the correction reliable everywhere — and it happens automatically on every run.

A 90° turn swaps width and height

A quarter-turn (left or right) swaps the frame's width and height: a 1920×1080 landscape clip becomes 1080×1920 portrait, and vice-versa. The result panel shows the before and after dimensions so you can confirm the new orientation at a glance. A 180° rotation and both flips keep the original dimensions, because they don't change which side is taller — they only change which way the picture faces.

Your audio is kept untouched

Rotating only changes the picture, so the audio is stream-copied — passed straight through without re-encoding. That means no quality loss on the sound and a faster export. The video itself is re-encoded once to H.264 in the widely-compatible yuv420p format; a single pass at CRF 23 is visually clean. A clip with no audio simply comes back silent, with no error.

Limits and privacy

Without an account you can rotate one file up to 100 MB and 5 minutes; a free account raises that to 200 MB and 10 minutes per file. The length cap keeps each rotation fast, because the video is re-encoded while you wait. Your files are processed securely, never shared, and automatically deleted after processing — no account is required to use the tool.

Rotate, crop or resize?

Rotating changes orientation only. If you need to cut the frame down to a rectangle, use the freeform Video Cropper; if you need a platform aspect ratio such as 9:16 for Reels or TikTok, use the Social Video Resizer; and to shrink the finished file, run it through the Video Compressor.
