Rotate Video – Turn a Sideways Video 90°, 180° or 270°
Rotate video files 90° right, 90° left or 180° and save the fix for good. For MP4 and MOV, which covers nearly every phone clip, ProMedia changes the rotation setting stored in the file instead of re-encoding the picture, so the turn is instant and lossless. A Re-encode option rotates the pixels themselves for old players that ignore the setting. Nothing is uploaded.

How to rotate a video
Step 1: Drop one or more videos on the box above.
Step 2: Choose 90° right, 180° or 90° left. Sideways phone videos usually need 90° right or left; upside-down ones need 180°.
Step 3: Keep Method on Instant for a lossless fix, or pick Re-encode if a player or editor still shows the video the wrong way.
Step 4: Press Rotate and download the turned video.
Good to know
Settings explained
- Method
- Instant works in phones, browsers and most players. Use Re-encode if an old player or editor ignores the rotation.
- Instant: Sets the rotation flag, no re-encode
- Re-encode: Rotates the pixels
Formats
Batch-friendly: add many files and they are processed one after another — if one fails, the rest still finish.
How it runs
- Hardware video engine
- Video is decoded and encoded by your device’s media hardware through WebCodecs — usually several times faster than real time.
- FFmpeg (when needed)
- Older formats and a few filters use FFmpeg compiled to WebAssembly. It downloads once (about 31 MB) the first time it is needed and is cached for offline use.
Instant or Re-encode: two ways to rotate a video
MP4 and MOV files carry a rotation setting that players read before showing the picture. Instant changes that setting, so nothing is decoded and nothing is lost. Re-encode turns every frame for real, which works in any player at the cost of time and a tiny bit of quality.
| Instant (default) | Re-encode | |
|---|---|---|
| What changes | The rotation setting in the file | The pixels of every frame |
| Quality | Identical to the original | Very close; encoded at a high quality setting |
| Speed | Seconds, even for long clips | As long as an export of the whole clip |
| Works in | Phones, browsers and most modern players and editors | Every player and editor, including old ones |
| Sound | Copied | Copied |
Can you rotate a video without losing quality?
Yes, with Instant. The compressed frames are copied into the new file unchanged and only the rotation setting is updated, so the picture is bit-for-bit the original. That setting also adds to the orientation your phone already recorded, which is why a clip filmed sideways can be fixed without touching a single pixel.
Some formats have no rotation setting. In those cases ProMedia picks the next best route automatically and says so on the result card.
| Your file | Instant rotation | Saved as |
|---|---|---|
| MP4, M4V, MOV (phones, cameras) | Rotation setting changed, lossless | Same format |
| MKV or WebM with H.264 or HEVC video | Moved into MP4 with the setting, lossless | MP4 |
| WebM or MKV with VP8, VP9 or AV1 video | Pixels rotated (re-encoded) | Same format |
| AVI, WMV, FLV and other older formats | Pixels rotated (re-encoded) | MP4 |
Why won’t my video rotate in some apps?
A few older players and editing programs ignore the rotation setting and show the raw frames, so an Instant fix can still look sideways there. Run the clip again with Re-encode: the frames themselves are turned, and every program shows them the same way.
If the picture is mirrored rather than turned (text reads backwards), rotating will not help. That needs a mirror, which Flip Video does horizontally or vertically.
Rotate a video on iPhone, Android, Windows or Mac
This video rotator works in any modern browser, one clip or a batch. The built-in tools below rotate one video at a time.
iPhone and iPad
In Photos, tap Edit, then the crop icon, then the rotate button until the clip is upright. Use this page in Safari for clips in Files or several videos at once.
Android
Google Photos rotates from Edit → Crop. Here in Chrome, pick several clips from your gallery and rotate them in one batch.
Windows 11
Windows Media Player can only play a video, not save it rotated; Clipchamp can rotate and re-export. Drag the file into Chrome or Edge here for an instant fix.
Mac
QuickTime Player has Edit → Rotate Left and Rotate Right for MOV and MP4. Use this page for MKV and WebM files or for batches.
Tips & troubleshooting
Rotating is not the same as making a video vertical for TikTok. To turn a landscape shot into 9:16 without lying it on its side, use the horizontal to vertical video converter.
Rotate before you crop: the crop tool works on the picture as you see it, so an upright video makes the box easier to place.
A whole folder of sideways clips? Drop them all at once; each file is rotated with the same angle.
Need to rotate a photo instead? Rotate Image turns JPG, PNG and HEIC pictures.
Rotate Video FAQ
How can I rotate a video 90 degrees?
Drop the video here, choose 90° right or 90° left and press Rotate. With Instant selected, an MP4 or MOV file is turned in seconds without re-encoding.
How do I rotate a video permanently?
Both methods save a new file with the rotation built in, so it stays rotated wherever you send it. Instant stores the rotation in the file’s settings, which phones, browsers and modern players follow; Re-encode turns the pixels themselves for the few programs that do not.
How do I rotate a video that was recorded upside down?
Choose 180° and press Rotate. If the picture also reads backwards, it is mirrored as well; fix that afterwards with Flip Video.
Can I rotate a video in Windows Media Player?
No. Windows Media Player can play a video but cannot rotate it or save it turned. Open this page in Edge or Chrome, drop the file and choose an angle; the rotated copy is saved to your Downloads folder.
Does rotating a video reduce its quality?
Not with Instant, which leaves the picture untouched. Re-encode decodes and encodes the frames again at a high quality setting, so the loss is very small but real.
Is your video uploaded anywhere?
No. Your video is processed by your own browser on your own device. There is no server that receives files, so nothing is uploaded, stored or shared. You can even switch to airplane mode once the page has loaded.
