A rotate tool that gets out of the way
See the turn before you run it
The preview turns live as you switch between 90° right, 90° left and 180°, so you pick the right direction by looking at it instead of guessing and re-exporting.
Three turns, one control
Quarter turn clockwise, quarter turn counter-clockwise, or a half turn. No menus of arbitrary angles to work through first.
Audio passed through untouched
The soundtrack is copied across rather than re-encoded, so a rotation costs you nothing in audio quality and barely any extra processing time.
Nothing cropped or stretched
A 90° turn simply swaps width and height, so a landscape clip becomes a portrait one with every pixel of the picture kept.
Takes the format your camera gave you
MP4, MOV, WebM, MKV, and AVI all go in as they are, and everything comes back as MP4, the format every editor and platform accepts.
Runs on your machine, not ours
ffmpeg.wasm does the work inside the browser tab. No upload, no server-side copy of your footage, no account to create first.
Rotate a video in three steps
- 1
Add the clip that plays sideways
Drop an MP4, MOV, WebM, MKV, or AVI file onto the page, up to 2GB. It is read straight off your disk, not sent anywhere.
- 2
Pick a turn: right, left, or 180°
Right turns the picture 90° clockwise, Left turns it 90° counter-clockwise, and 180° turns it upside down. The preview turns as you switch, so you can see the right answer before committing.
- 3
Rotate and save the MP4
One click rotates the clip in your browser and hands back an MP4 you can download immediately. No queue, no watermark, no account.
When a clip needs turning
A phone clip that plays on its side, an action-cam recording that came out upside down, or landscape footage that needs to be portrait: each one is a single turn away from fixed.
Fixing a phone clip that plays sideways
A video shot with the phone held awkwardly, or one that a player ignores the orientation note for, lands on its side. A quarter turn puts it upright for good.
Turning an upside-down recording the right way up
Action cameras, dash cams and mounted rigs often record inverted. A 180° turn fixes the whole clip in one pass.
Making landscape footage portrait for a feed
Filmed sideways on purpose, or need a tall clip for Stories and Reels? A 90° turn swaps landscape for portrait without cropping anything away.
Matching clips before you cut them together
Footage from different devices arrives in different orientations. Turning the odd one out gets every clip facing the same way before it goes on the timeline.
Frequently asked questions
Why does my video play sideways or upside down?
+
Phones and cameras record the picture in the sensor's native orientation and add a note saying how to turn it for display. Some players, editors and upload forms ignore that note, so the clip shows up on its side. Rotating it here bakes the correct orientation into the pixels, so it looks right everywhere.
Which direction should I choose?
+
Look at which side the top of the picture is on. If the top of the scene points left, the clip needs 90° right (clockwise). If the top points right, it needs 90° left (counter-clockwise). If the whole picture is upside down, choose 180°. The preview shows the result before you run it.
Does rotating a video lose quality?
+
Turning the picture rewrites the position of every pixel, so the video cannot be copied through untouched and has to be re-encoded. PixelTools encodes with H.264 at CRF 23, a visually lossless setting, so a single rotation is not something you will see. Rotating the same file over and over will slowly soften it, as any repeated re-encode would.
What happens to the frame size?
+
A 90° turn swaps width and height, so a 1920×1080 landscape clip becomes 1080×1920 portrait, and the other way round. A 180° turn keeps the size as it was. Nothing is cropped or stretched in either case.
What happens to the sound?
+
Nothing at all. The audio stream is copied across byte for byte rather than re-encoded, so it stays exactly as clean as the original and adds almost no processing time. That includes a WebM source: its audio keeps its original codec, so a few older players may not play Opus or Vorbis inside an MP4.
Is rotating the same as flipping?
+
No. Rotating turns the frame around its centre, so text stays readable. Flipping mirrors the frame across an axis, so text comes out backwards. If a clip is sideways or upside down, you want rotate. If writing in it reads in reverse, you want the Flip Video tool instead.
How long does a rotation take?
+
It scales with resolution and length, since every frame is re-encoded on your own machine. A one-minute 1080p clip typically finishes in well under a minute on a modern laptop; a long 4K file takes proportionally longer. The progress bar tracks ffmpeg's real position in the file, not an animation.
Do my videos get uploaded to PixelTools?
+
They do not. The rotation runs through ffmpeg.wasm inside your own browser tab, so the file never crosses the network. That also means no upload wait, no server queue, and nothing of yours sitting in someone else's storage afterwards.
