What is Video Rotator?

This rotate video online tool fixes the all-too-common problem of a sideways video recorded accidentally in the wrong orientation, letting you flip video online free to the correct rotation before sharing or uploading it. Whether you need to rotate mp4 90 degrees or flip a video vertically, this tool corrects orientation without needing video editing software. It's a quick fix for a very specific, very common annoyance.

How It Works

This tool runs FFmpeg compiled to WebAssembly directly in your browser tab to apply a rotation or flip transform filter to your video's frames, re-encoding the video with the corrected orientation baked in, the same filtering approach used by professional video editors. This ensures the fixed orientation displays correctly on every device and platform, not just ones that respect rotation metadata.

Is It Safe to Use?

Your video is processed entirely within your browser tab using WebAssembly FFmpeg, so it's never uploaded to a server. This keeps personal clips of family, events, or private moments secure while you fix sideways video footage.

Frequently Asked Questions

Why does my video play sideways even though it looked fine when recording?

This usually happens because the video was recorded with a rotation flag in its metadata that some players and platforms don't read correctly, which is exactly the fix sideways video problem this tool solves.

Can I rotate mp4 90 degrees in either direction?

Yes, you can rotate clockwise or counterclockwise by 90 degrees, or flip a full 180 degrees if the video is completely upside down.

Does rotating a video reduce its quality?

There's minimal quality impact from re-encoding, and at standard quality settings the difference is generally unnoticeable.

What's the difference between rotating and flipping a video?

Rotating turns the video by an angle like 90 or 180 degrees, while flipping mirrors the video horizontally or vertically, like a mirror image.

Is there a file size limit when I flip video online free?

Videos up to a few gigabytes typically process without issue, since everything runs using your device's own processing power.

Does this tool work on mobile phones?

Yes, it works in mobile browsers on Android and iOS for fixing videos recorded directly on your phone.

Will the fixed video play correctly on all platforms after rotating?

Yes, since the rotation is baked into the actual video frames rather than relying on metadata, it will display correctly everywhere.

Is this video rotator free with no watermark?

Yes, it's completely free and the rotated video has no watermark added.
