Flip a video, like a mirror.
Un-mirror a selfie recording or flip any clip left to right. Turn it too, if you need. On your device, nothing uploaded.
How do I flip or mirror a video for free?
Keep Mirror selected and drop the video into Cutmallow's free tool above. Every frame is flipped left to right and saved as an H.264 MP4 at high quality, so it looks mirrored in every player and app. To turn a sideways video instead, pick Turn right, Turn left or Turn 180°: turns are saved without re-encoding, so they take seconds. Nothing is uploaded and there's no watermark.

How to use it
Keep Mirror selected (or pick a turn).
Drop a video, or tap to pick one.
Save the MP4. On a phone, the share sheet offers Save Video.
How it works
Front cameras show you a mirror image while you record, and some phones and apps save the video that way, so text reads backwards and your parting is on the wrong side. Mirroring fixes that by flipping each frame horizontally, swapping left and right.
Video files can carry a mirror flag, but most players and websites ignore it, so the flip is baked into the frames: each one is decoded, flipped and encoded again to H.264 by your device’s own video encoder (WebCodecs). Turns are different: every phone and player honours the rotation setting in an MP4, so a turn is written there and the video itself is copied, untouched.
It runs on Mediabunny, an open-source media library, in a background thread of the page. Your video never leaves your device.
Tips for a better result
- Selfie video with backwards text? Mirror fixes it.
- Sideways video? Use a turn instead: it is lossless and takes seconds.
- For a vertical 9:16 Short from a landscape clip, use the Instagram resizer.
Turn it into a Short
Cutmallow's free editor finishes the job. After flipping, tap Edit in Cutmallow and your MP4 opens there, still on your device.
- Cuts the pauses and filler words
- Writes animated word-by-word captions
- Exports a 9:16 MP4 for Shorts, Reels and TikTok

How do I un-mirror a selfie video?
Drop it in with Mirror selected and save the MP4. Every frame is flipped back, so text reads the right way round. The original video is not changed.
How do I mirror a video on iPhone?
Open this page in Safari, keep Mirror selected, tap the drop box and choose the video from Photos. Tap Save MP4 when it is ready: the share sheet offers Save Video.
Does flipping lower the quality?
A mirror re-encodes the video once at a high bitrate, which looks the same to the eye. A turn (90° or 180°) does not re-encode at all.
Is my video uploaded anywhere?
No. Your video never leaves your device. The file is opened and processed by your own browser, and the result is saved straight from your device.
Is there a file size or length limit?
No. The file is read from your device a piece at a time and the result is written to the browser’s private storage, so long and very large videos work. The only limit is free space on your device.
