How to rotate a video

1Upload your video
Drag and drop the sideways MP4, WebM, or MOV file onto the upload box, or click it to browse your files.
2Rotate until it looks right
Tap “Rotate left” or “Rotate right” to turn the video 90 degrees at a time, or “Flip 180 degrees” for upside-down clips. The preview updates instantly.
3Export the fixed video
Hit Export and the tool re-renders every frame with the new orientation. A 60-second clip exports in about a minute.
4Download and share
Save the finished file and post it to Reels, TikTok, or YouTube — the rotation is baked into the pixels, so it plays upright on every device.

Why use this video rotator

90°, 180°, and 270° rotation

Turn a clip left or right in 90-degree steps, or flip an upside-down video 180 degrees in one tap.

Live rotated preview

The preview canvas shows the true rotated picture while the video plays — no guessing, no re-exporting.

Keeps full resolution

A 1920 x 1080 landscape clip rotated 90 degrees becomes a crisp 1080 x 1920 portrait video — no stretching, no black bars added.

Permanent fix, not metadata

The pixels themselves are re-rendered, so the video plays upright in every player, phone, and social app — even ones that ignore rotation tags.

No watermark, ever

Exports are clean. Paid tools charge a subscription to remove their logo — here it was never added.

Private by design

Everything runs on your device with browser APIs. Close the tab and your video is gone from memory.

Frequently asked questions

Why is my video sideways in the first place?

Phones record a small orientation tag with each clip. Some apps and players ignore that tag, so a video shot in portrait can play sideways. Rotating here rewrites the actual pixels, which fixes it everywhere.

Will rotating reduce the video quality?

The video is re-encoded, but at a high 8 Mbps bitrate the result is visually identical to the original for typical phone footage. Resolution is preserved — 90-degree turns simply swap width and height.

Will the exported video play upright on iPhone and Android?

Yes. Because the rotation is baked into the pixels rather than stored as a metadata hint, the file plays upright in every player, gallery app, and social network.

What format is the exported video?

Chrome and Edge export MP4; Firefox exports WebM. Both play everywhere modern — YouTube, TikTok, Instagram, and all phones accept them.

Can I turn a vertical video into a horizontal one for YouTube?

Yes — rotate 90 degrees and your 1080 x 1920 portrait clip becomes a 1920 x 1080 landscape video that fills a YouTube player perfectly.

Does this work on iPhone?

Yes. Upload a clip from your camera roll in Safari or Chrome on iOS, rotate, and export. For very large files, a desktop browser with more memory works faster.

Is there a file size limit?

There is no artificial limit — the ceiling is your device’s memory. Clips under about 500 MB rotate smoothly on most phones and laptops.

Is my video uploaded to your servers?

No. The file never leaves your device — all processing happens locally in your browser tab using standard web video APIs.
