A mirror tool that gets out of the way
See the flip before you run it
The preview mirrors live as you switch between horizontal and vertical, so you pick the right axis by looking at it rather than by guessing and re-doing the export.
Both axes, one control
Horizontal mirrors left to right, vertical mirrors top to bottom. Two options, no menus of angles and crops to work through first.
Audio passed through untouched
The soundtrack is copied across rather than re-encoded, so a flip costs you nothing in audio quality and barely any extra processing time.
Frame size preserved
Mirroring never changes dimensions or aspect ratio — a 1080×1920 vertical clip comes back 1080×1920, ready to drop straight back into the timeline it came from.
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 every 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.
Flip a video in three steps
- 1
Add the clip you want mirrored
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 horizontal or vertical
Horizontal swaps left and right, which is what un-mirrors selfie and webcam footage. Vertical swaps top and bottom. The preview mirrors as you switch, so you can see the answer before committing.

Flip and save the MP4
One click runs the mirror in your browser and hands back an MP4 you can download immediately — no queue, no watermark, no account.
When a clip needs mirroring
Reversed text in a webcam recording, a presenter facing the wrong side of the frame, two shots whose eyelines refuse to match, or a repost that should not be a byte-identical duplicate — each one is a single flip away from fixed.
Un-mirroring selfie and webcam footage
Front-camera recordings arrive reversed, so any text on screen — a whiteboard, a product label, a slide — reads backwards. One horizontal flip puts it right without touching anything else in the shot.
Making a subject face the other way
A presenter looking off to the right can be mirrored to look left, which is how you get a talking head to face into your title card, your b-roll, or the other speaker in a split screen.
Matching two clips before you cut them together
Footage shot from opposite sides of a subject cuts badly because the eyelines disagree. Mirroring one of the two puts both on the same side and makes the edit read as continuous.
Reposting without an exact duplicate
Social platforms fingerprint re-uploads of identical files. A mirrored copy is pixel-different from the original while looking the same to a viewer, which is why creators flip a clip before posting it a second time.
Frequently asked questions
Why does my webcam video have backwards text, and does flipping fix it?
+
Front-facing cameras and most webcam apps show you a mirrored image so moving left feels natural, and many of them record that mirrored image too. Anything with writing in it — a whiteboard, a book cover, a logo on a hoodie — comes out reversed. A horizontal flip is exactly the inverse of that mirroring, so it puts the writing back the right way round.
Which direction should I choose?
+
Horizontal for almost everything: it is the un-mirror for selfie footage and the way to make a subject face the other side of the frame. Vertical is much rarer — it inverts the picture top to bottom, which is not the same as rotating a sideways clip 180°, and is mainly used for reflection effects or footage from an inverted camera rig.
Does flipping a video lose quality?
+
Mirroring rewrites the position of every pixel, so unlike trimming or muting there is no way to copy the video stream through untouched — it has to be re-encoded. PixelTools encodes with H.264 at CRF 23, a visually lossless setting, so a single flip is not something you will see. Flipping the same file over and over will slowly soften it, as any repeated re-encode would.
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 loud and as clean as the original and adds almost no processing time. The one exception is a source whose audio codec an MP4 cannot hold — Opus or Vorbis inside a WebM, typically — where the audio is converted to 192 kbps AAC so the result still plays everywhere.
Is flipping the same as rotating?
+
No, and they are not interchangeable. Rotating turns the frame around its centre, so a 90° rotation swaps width and height. Flipping mirrors the frame across an axis and leaves the dimensions alone — a 1920×1080 clip stays 1920×1080. Text survives a rotation and reads backwards after a flip, which is the quickest way to tell which one you actually need.
How long does a flip 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 frame position, so the number it shows is the actual state of the encode, not an animation.
Do my videos get uploaded to PixelTools?
+
They do not. The mirror runs through ffmpeg.wasm inside your own browser tab, so the file never crosses the network — which also means there is no file-size ceiling imposed by an upload, no waiting on a server queue, and nothing of yours sitting in someone else's storage afterwards.
Can I flip a video on my phone?
+
Yes — the page works in mobile Safari and Chrome without installing anything. Bear in mind that a phone has less memory and a slower CPU than a laptop, so a very long 4K clip is better handled on a desktop; short vertical clips shot for social feeds flip comfortably on the phone itself.
