rotate.video

You film something on your phone, open it somewhere else, and it plays sideways. The good news is that a sideways phone video usually isn't damaged. It carries a small flag that tells players which way is up, and some apps ignore it or set it wrong. rotate.video fixes the common case by rewriting that flag. For turns of 90, 180 and 270 degrees the picture itself is left untouched, so nothing is re-encoded, no quality is lost and the new file is ready almost at once.

The team behind rotate.video says rotating a sideways phone clip usually means opening a full editor or uploading the video to a converter site, and that most of those re-encode the whole file. Here you drop a clip on the page and press Turn left or Turn right, or use the left and right square bracket keys. One press of Upside down handles a clip that plays inverted.

Some fixes mean redrawing the video. A selfie or webcam clip where text reads backwards is mirrored, and flipping it means redrawing every frame. So does straightening a tilted horizon by a few degrees. More options has exact angles, Straighten and the canvas settings, where you choose between Fill and Crop for the empty corners a small rotation leaves. Trimming works the same way, by dragging the handles or pressing I and O at the playhead.

The site says these changes re-encode at a high bitrate so the result stays close to the original. They aren't lossless, and it's honest about that.

Two gaps are worth knowing. You can't rotate only part of a video yet, so the turn applies to the whole clip, or to the trimmed part you keep. The team also warns that some older players and editors ignore the orientation flag a lossless turn writes. For those, the Maximum compatibility option draws the rotation into the picture, which re-encodes.

The about page promises no watermark, no signup, no daily limit and no paid tier, and says there's no advertising. MP4, MOV, WebM and MKV files open directly, with no fixed cap on file size or length.

According to the privacy page, updated November 6, 2026, clips are turned, flipped and straightened by your own browser and the site never sees them. A Recent videos shelf keeps your 24 most recent exports in the browser until you remove them or newer ones replace them, and clearing the site's data erases the lot. Analytics cookies can be switched off from Cookie settings in the footer. No person or company is named on the site.

If you'd rather fix the clip in software you already have, there are step-by-step guides for iPhone, Android, Windows and Mac, along with VLC, CapCut and FFmpeg. Otherwise, the next time a video lands on its side, drop it on the page and press a button.
