Free Video Rotator
Rotate videos 90°, 180°, or 270° in-browser. Fix sideways phone recordings with one click. No upload, no signup, no watermark.
Why Do This in Your Browser?
Sideways phone videos are the single most common video problem people face. The phone records vertical with the orientation flag set, but somewhere along the chain (text message, email, upload, copy) the flag is lost or ignored, and the video plays sideways forever. Fixing this should be one click — it usually isn't.
This tool fixes it in one click. Drop the video, pick a rotation, export. When possible, the rotation is metadata-only — just flipping the orientation flag in the container, no re-encode, byte-exact, completes instantly. When the player ignores metadata orientation (which some players still do), an explicit re-encoded rotation is one toggle away.
How It Works
Container-level rotation is a metadata change: the MP4 'rot' atom is updated, signaling to every modern player that the video should be rotated on playback. No pixel data changes. This is what every phone recording app does when you tilt the phone, and what every modern player respects. The export takes seconds and is byte-exact for the video stream.
Sometimes that's not enough. Old players, embedded video in slide decks, and certain web frameworks ignore the metadata flag and play the video in its original orientation. For those cases, toggle 'physical rotation' — the tool re-encodes the video with the rotation baked into the pixels. Larger file, slower export, but plays correctly everywhere.
Tip: Rotation often needs a follow-up resize — phone portrait video rotated to landscape ends up at unusual aspect ratios. Fix it with the Video Resizer. After rotation, shrink the file if you're sharing it.
