How to rotate a video
Drop your video above, pick a direction, and press Rotate video. The preview turns as you choose so you can check the result before saving. Clockwise turns the top of the picture towards the right: if people's heads point to the left, you want 90° clockwise; if they point right, 90° counter-clockwise; if everything is upside down, 180°.
You can drop several files at once — a whole folder of sideways phone clips, say — and every one is rotated the same way. With one file you get a preview of the result; with several you get a list to save from, or a single ZIP.
Why rotating here does not cost quality
A video file does not have to store its frames the right way up. Phones never do: the camera sensor always captures a landscape image, and when you film in portrait the phone writes a small instruction into the file — a display matrix — telling players to turn the picture 90° on playback. That is why the same clip can look right on your phone and sideways somewhere that ignores the instruction.
This tool uses the same mechanism. For MP4 and MOV files it rewrites the display matrix and copies the compressed video across untouched, so the result is bit-for-bit the same picture, just labelled with a new orientation. Nothing is decoded or re-encoded, which is also why a twenty-minute clip rotates in about the time it takes to copy the file. The result card tells you when a file was copied this way.
Most online rotators decode every frame, turn it, and compress it again. That takes as long as a full conversion and every re-encode loses a little detail — more each time if a clip is rotated, edited and exported repeatedly.
When to burn the rotation in instead
Current browsers, iPhones and Android phones, VLC, QuickTime, YouTube and the major social platforms all honour the display matrix. A few things do not: some older video editors, certain CCTV and kiosk players, and tools that re-wrap a file and drop its metadata. If one of those still shows your video sideways, tickBurn the rotation into the picture. The video is then re-encoded with the pixels physically turned and no flag left to ignore. It takes longer and the file is a fresh encode, but it plays the right way up everywhere.
WebM files have no display matrix, so rotating one always re-encodes it. The output stays in the same format family where possible, and the result card says when this happened.
Rotate, flip or crop?
Rotation turns the whole frame. If the picture is mirrored — text reads backwards, as in a front-camera selfie — you want to flip the video instead. If it is the right way up but has black bars or the wrong shape, crop it, or useChange Aspect Ratio to reframe landscape footage as 9:16 for Reels, Shorts and TikTok.
Frequently asked questions
Does rotating a video reduce its quality?
Not here. For MP4 and MOV files the rotation is written into the file's display matrix — the same flag your phone sets when you film in portrait — and the video itself is copied byte for byte. Nothing is decoded or re-encoded, so the picture is identical to the original and even a long clip finishes in a second or two.
Why does my phone video play sideways on my computer?
Phones record the sensor's native landscape image and add a rotation flag saying how to display it. Most players honour that flag, but some older players, editors and upload pipelines ignore it, and a few apps strip it when they re-save a file. Rotating 90° here writes the correct orientation back in.
What does "Burn the rotation into the picture" do?
It re-encodes the video with the pixels physically turned, instead of storing the rotation as a flag. Use it only if a specific app still shows the video sideways after a normal rotate — it takes longer and costs a little quality, but every player shows it the right way up because there is no flag left to ignore.
Which way is 90° clockwise?
Clockwise turns the top of the picture towards the right. If your video is lying on its left side — people's heads pointing left — rotate 90° clockwise. If heads point right, rotate 90° counter-clockwise. If it is upside down, rotate 180°. The preview turns as you choose, so you can check before saving.
Can I rotate several videos at once?
Yes. Choose several files and every one is rotated by the same amount. Each is processed in turn, and you can save them one at a time or all together as a ZIP.
Is my video uploaded?
No. The file is read and rewritten inside your browser tab; nothing is sent to a server. That is also why it is fast — there is no upload or download queue.
