Flip Video (Mirror) lets you mirror any clip horizontally (left-to-right) or vertically (top-to-bottom) in seconds. A horizontal flip is the classic mirror effect that corrects selfie footage and reversed text, while a vertical flip turns the image upside down — useful for fixing clips recorded with the camera inverted. Your audio stays perfectly in sync and untouched.

Everything runs locally in your browser using ffmpeg.wasm, a WebAssembly build of FFmpeg, so your video is never uploaded to a server. The tool applies FFmpeg's hflip or vflip filter directly on your device, then hands you an MP4 to download. It is free, requires no signup, and works on any modern browser — ideal for creators, marketers, and anyone who needs to mirror footage privately.

Why use this tool

Fix mirrored selfie footage

Horizontally flip front-camera and webcam clips so text reads correctly and the image matches what viewers expect, undoing the mirror effect many devices apply.

Both flip axes in one tool

Switch between a horizontal mirror (hflip) and a vertical flip (vflip) with a single click, covering both reversed-image and upside-down camera fixes.

Completely private processing

Your footage is flipped locally with ffmpeg.wasm and never uploaded, so sensitive or unreleased videos stay entirely on your own device.

Audio stays untouched

Only the picture is mirrored — the original audio stream is copied without re-encoding, preserving perfect sync and full sound quality.

How to use the Flip Video (Mirror)

  1. Upload your video

    Drag and drop your clip into the tool or click to select it from your device; it loads directly in your browser with no upload.

  2. Choose a flip direction

    Select horizontal to mirror the video left-to-right or vertical to flip it top-to-bottom (upside down).

  3. Preview the result

    Check the on-screen preview to confirm the mirror direction looks correct before processing.

  4. Flip the video

    Click the flip button to apply the hflip or vflip filter with ffmpeg.wasm; your audio is copied unchanged and stays in sync.

  5. Download the MP4

    Save the flipped MP4 file straight to your device once processing finishes, ready to share or upload anywhere.

Popular use cases

  • Mirroring a webcam or phone selfie recording so on-screen text and logos read the right way around instead of reversed.
  • Flipping a product or unboxing clip horizontally to match a specific composition or to align with other footage in an edit.
  • Correcting a video shot with a phone or action camera mounted upside down by applying a vertical flip.
  • Creating a mirrored version of dance, fitness, or tutorial footage so viewers can follow along facing the same direction as the instructor.

Frequently asked questions

Is this video flip tool free to use?
Yes, Flip Video (Mirror) is completely free with no signup, watermark, or usage limits. You can flip as many videos as you want, as often as you want. There are no paid tiers or hidden charges.
Are my videos uploaded to a server when I flip them?
No. The tool processes your video entirely in your browser using ffmpeg.wasm (WebAssembly), so the file never leaves your device. Nothing is uploaded, stored, or seen by anyone, which makes it safe for private or confidential footage.
What is the difference between a horizontal and a vertical flip?
A horizontal flip (hflip) mirrors the video left-to-right, creating the classic mirror effect that un-reverses selfie footage and flipped text. A vertical flip (vflip) mirrors the video top-to-bottom, effectively turning the image upside down to fix clips recorded with an inverted camera.
What video formats are supported?
You can flip common formats including MP4, MOV, MKV, WebM, AVI, and M4V, since ffmpeg.wasm reads the same broad range of inputs as FFmpeg. The flipped result is exported as an MP4 file (H.264 video with the original audio) for maximum compatibility.
Will flipping reduce my video's quality?
Flipping rearranges pixels rather than degrading them, so there is no visible quality loss from the mirror operation itself. The audio track is copied without re-encoding, and the video is re-encoded once to apply the flip, which keeps quality very close to the original at standard bitrates.
Is there a file size limit?
There is no hard server limit because processing happens locally, but practical performance depends on your device's available memory. Clips up to roughly a few hundred megabytes flip smoothly on most computers, while very large or long files may process slower or strain browser memory.
How fast is flipping a video?
Most short clips flip in a matter of seconds. Because the flip filter is computationally light, speed is mainly determined by re-encoding time, which scales with the video's length, resolution, and your device's CPU. A 1080p clip of a minute or two typically finishes quickly on a modern laptop.
Does flipping the video also flip or mute the audio?
No, your audio is left completely intact. The tool only applies the hflip or vflip filter to the visual frames and copies the original audio stream as-is, so sound stays in sync and at full quality.
