Rotate Video
Rotate Video fixes footage that was filmed sideways or upside down. Turn a clip 90, 180 or 270 degrees, or mirror it horizontally or vertically, with a live preview of the result — then export the corrected video without ever uploading it.
Add your video
The file is read by your browser and stays on your device — there is no upload step.

The work runs in this tab. Nothing is sent anywhere, and the download is generated locally.
How to use Rotate Video
- 01Upload
Add your video
Drop the file in and it plays in the preview so you can see the current orientation.
- 02Customize
Rotate or flip
Use the rotate-left and rotate-right buttons in 90° steps, and flip horizontally or vertically as needed.
- 03Process
Export
Export to bake in the new orientation and download the fixed clip.
What rotating does
Turns the frame in 90° steps and swaps width for height. Phone footage that plays sideways is the usual reason: the camera recorded an orientation flag, and something in the chain between the phone and your screen ignored it.
What does not change
Duration, audio, frame rate and resolution — the numbers simply swap. The clip is re-encoded once to bake in the rotation, so there is a single generation of loss, unlike the repeated re-encoding that damages a file over many edits.

Your file, and what the page does
Your file is never uploaded. Rotate Video reads it into this browser tab and processes it with FFmpeg compiled to WebAssembly on your own device. There is no upload endpoint in the application and no copy on any server — closing the tab discards it.
That is also why processing takes longer here than on a site that uploads: your device is doing the work rather than a rack of servers. The trade is that the file never leaves it.
What the page does send or fetch
- The processing engine, once
- The first time you use any video or audio tool, the browser downloads the FFmpeg WebAssembly build (~30MB) from the jsDelivr CDN and reuses the cached copy afterwards. That is a file coming to you — no part of your own file is in the request.
- Ads on the page
- The site is funded by advertising, so the page loads Google AdSense. That carries the usual web basics — IP address, browser, referring page — as on any ad-supported site.
- An anonymous usage counter
- When Rotate Video finishes we record that the tool ran, whether it succeeded and how long it took. No file data, no identifier, no cookie.
Your file is not on that list. How this works.
Frequently asked questions
Yes — rotate left or right in 90° steps to reach 90, 180 or 270 degrees, and combine with a flip if needed.
Some players ignore the orientation flag in phone footage. Rotating and re-exporting bakes the correct orientation into the file.
The clip is re-encoded once at high quality, so any change is negligible.
Yes — Rotate Video is completely free. There's no account, sign-up, watermark or limit.
No. It runs in any modern browser — Chrome, Edge, Safari, Firefox, Brave — with nothing to download or install.
