Rotate Video Online
Use Rotate video Online, review the result, and keep the original until the output is checked.
How to use Rotate video Online
- Add one or more videos.
- Press a Rotation Angle button (0, 90, 180, 270), set Custom Angle for anything between, and add Horizontal or Vertical flip if needed.
- Set Quality (1-35). Pick Output Format last: MP4 keeps the smallest file, and WebM re-encodes to VP9, which is slower here.
- Press Convert All, then Download All.
What Rotate video Online actually does to your file
A quarter turn swaps width for height, so a landscape clip becomes vertical and the player may show it differently afterwards. An angle that is not a multiple of 90 degrees keeps the whole picture by growing the frame - a 640x360 clip arrived at 706x706, black in the four corners - so the extra pixels also cost extra bytes; use Crop Options afterwards if you want the original box back. WebM is a different encoder: the same 6 second clip took about 28 seconds and came out at 1.1 MB against 0.5 MB for MP4. Re-encoding is unavoidable, so rotate once rather than repeatedly.
Rotate Video Online FAQ
What does Rotate video Online do?
Easily rotate your video online without any watermarks. Flip or rotate videos by 90°, 180°, or 270°—change from portrait to landscape effortlessly!
Which files work with Rotate video Online?
This category commonly supports MP4, MOV, AVI, MKV, WMV, FLV, WebM, and 3GP. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Can I rotate by an angle other than 90 degrees?
Use the custom angle for straightening a horizon or a scanned page. Non-right angles add padding or crop the corners, so review the preview before downloading.
Will my original file be changed?
No. The work is done on a copy in this tab by a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the Rotate video Online free?
Yes. The Rotate video Online is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
