About the Flip Video
Front cameras often save videos as a mirror image, so writing on a T-shirt or a sign reads backwards. This tool mirrors the video left to right to fix it, or flips it upside down, for example for footage from a camera mounted the wrong way. Every frame is re-encoded so the flip shows in any player, and the result is a high-quality MP4 with the original sound. It all runs in your browser, so the video stays on your device.

When to mirror a video
Mirroring fixes selfie videos with backwards text, makes a dance tutorial easier to follow by matching the viewer's left and right, and corrects footage recorded through a mirror or a teleprompter.
- Selfie videos with backwards writing
- Dance and exercise tutorials
- Videos shot through mirrors
- Dash cams mounted upside down
Why every frame is re-encoded
Unlike rotation, there is no widely supported setting that tells players to mirror a video, so the tool redraws every frame mirrored and saves a new MP4. That guarantees the flip shows on every phone, TV and website.
How it works without uploading
Your browser has a built-in video engine (WebCodecs) that phones and computers use to play and record video. This tool uses it through Mediabunny, an open-source media library, to read your file, change it and write a new one, all inside the page. Speed depends on your device: a recent phone or laptop handles a few minutes of HD video comfortably, while long 4K files take longer.
Upside-down footage
Action cameras and dash cams are sometimes mounted upside down. Choose Upside down to fix it. If the footage is also mirrored, run the tool twice, first Upside down and then Mirror; or use Rotate Video with 180°, which turns it the right way without mirroring.
Mirror selfie cameras
Many phones show the front camera as a mirror so it feels natural, like looking into a mirror, but some also save the video mirrored. iPhone and Android usually have a Mirror front camera setting; switching it off avoids the problem for future videos, while this tool fixes ones you already recorded.
File size and format
The flipped video is saved as an MP4 with H.264 or the best codec your browser can encode, at high quality. Its size is usually similar to the original; use the Video Compressor afterwards if you need it smaller.
Phone and computer
Flipping works on phones and computers; keep the page open while it runs. If the clip also needs a straight edge trimmed away, the Crop Video tool removes the extra border after you flip it.

Frequently asked questions
How do I fix a mirrored selfie video?
Choose Mirror (left ↔ right). Text and logos will read the right way round.
What is the difference between flipping and rotating?
Flipping makes a mirror image. Rotating turns the picture around its centre. Upside down here is a true vertical flip, the same as mirroring top to bottom.
Will flipping reduce quality?
Each frame is re-encoded at high quality, so the difference is very hard to see.
How long does it take?
Roughly as long as the video plays, quicker on fast computers.
Which browsers work best?
Chrome and Edge on computers and Android support the most video formats. Safari 16.4+ and recent Firefox work too, but some codecs, such as HEVC in Firefox, may not be supported there.
Is my video uploaded?
No. It is processed on your own device with your browser's built-in video engine, so private videos never leave your phone or computer.
Will the sound be flipped too?
No. Sound is copied as it was; only the picture is mirrored.
