How to rotate a video online

  1. Add your video

    Drop the sideways clip onto the tool or click to browse. MP4, MOV, WebM, MKV, and AVI files are accepted.

  2. Pick an angle

    Choose 90, 180, or 270 degrees clockwise. Toggle a horizontal or vertical flip on top if the footage is also mirrored.

  3. Rotate video

    Click Rotate video. The clip is re-encoded at the new orientation, so the fix sticks in every player instead of relying on orientation hints.

  4. Download

    The result card shows the old and new dimensions plus a preview player. Click Download to save the MP4.

Why use this tool

Quarter turns plus flips

Rotations of 90, 180, and 270 degrees clockwise combine freely with horizontal and vertical mirror flips, so any orientation is reachable in a single pass.

Dimension swap shown

A quarter turn trades width for height, and the result card spells it out: a 1920x1080 landscape clip becomes a 1080x1920 portrait one.

Built for phone footage

The classic sideways phone recording, the upside-down mount, and the mirrored selfie clip are all one click from upright.

Preview before saving

The rotated clip plays inside the result card, so you can confirm which way is up before downloading anything.

Standard MP4 output

Every result is an MP4 with H.264 video and, when the source has sound, AAC audio, which plays on practically every device and editor.

Nothing is uploaded

The rotation runs entirely in your browser, so the clip never leaves your device.

About this tool

This tool turns a video by 90, 180, or 270 degrees clockwise and writes a new MP4, with optional horizontal and vertical mirror flips layered on top. It runs entirely in your browser. Pick an angle, add a flip if needed, and click Rotate video; the result card shows the original dimensions next to the new ones, so a quarter turn on a 1920x1080 clip visibly becomes 1080x1920, and a preview player lets you check the orientation before saving.

The classic case is the sideways phone recording: the phone was held the wrong way, or a player ignored the orientation hint, and the clip plays lying down. A 90 or 270 degree turn puts it upright and bakes the fix into the pixels, so it stays upright everywhere. Flips handle mirrored selfie and webcam footage where text reads backwards, and 180 degrees rescues clips from upside-down mounts. Rotating also helps when you are mixing portrait and landscape clips and need them all facing the same way. The change requires a full re-encode, so a short clip takes seconds while a long one takes minutes, and a desktop browser handles big files more comfortably than a phone. Silent videos work without any extra steps.

Processing is local, so the footage never leaves your machine. For a still photo that displays sideways, rotate an image instead, since pixels in a photo need a different tool than frames in a clip. Cutting a long recording down with the video trimmer before rotating saves time, and a rotated file that comes out too heavy can go through the video compressor afterwards.

Frequently asked questions

How do I rotate a video?
Drop a video onto the tool or click to browse, pick 90, 180, or 270 degrees clockwise, and add a horizontal or vertical flip if you need one. Click Rotate video, check the preview and the dimension readout in the result card, then click Download to save the new MP4.
Which way does the rotation go, and can I flip at the same time?
All three angles turn the video clockwise, so 270 degrees clockwise is the same as 90 degrees counterclockwise. The two flips mirror the picture across the horizontal or vertical axis, and both can be combined with any angle in the same pass, so mirrored and sideways footage is fixed in one go.
Will rotating reduce the quality of my video?
Rotating re-encodes the video, so there is some quality loss, but for everyday footage it is hard to notice. The pixels themselves are only turned, never scaled, and the output is a standard H.264 MP4 that plays everywhere. A short clip takes seconds to process, while a long video can take a few minutes.
Which video formats are supported?
You can drop in MP4, MOV, WebM, MKV, AVI, and most other common video files. The output is always an MP4 with H.264 video and, when the source has sound, AAC audio. If you only need a format change without turning anything, convert to MP4 does that on its own.
Does it work on videos with no sound?
Yes. If a video has no audio track, the tool simply rotates the picture and writes a silent MP4, so screen recordings and animations need no special handling. When the source does have sound, the audio is carried over untouched in timing and stays in sync.
Is my video uploaded to a server?
No. The entire rotation runs locally in your browser. Your video never leaves your device, is never uploaded, and is not stored or logged anywhere. The first time you use the tool, it downloads the video engine once, then keeps it ready for the rest of your session.
