Flip an MP4 video
Drop an MP4 and mirror it horizontally, vertically, or both. The picture is re-encoded at your source’s bitrate while the audio is copied through untouched. Your file never leaves your device.
About flipping a video
Flipping is handy for correcting footage shot through a mirror or a front-facing camera, matching the orientation of another clip, or creating a mirrored effect. Horizontal mirrors the frame left-to-right, vertical flips it top-to-bottom, and both together is equivalent to a 180° rotation. Because the picture must be re-encoded, we pin the video bitrate to your source’s budget so quality is preserved, and the audio track is copied through without any re-encoding.
Is it private?
Yes. The converter is WebAssembly and browser APIs running on your own machine. Nothing is uploaded, stored, or seen by us — there is no server to send files to.
Frequently asked questions
- What does flipping do to the video?
- Horizontal mirrors the picture left-to-right (a mirror image), vertical flips it top-to-bottom, and both flips on both axes — which looks the same as rotating 180°. Only the picture changes; the audio stays in sync.
- Is the audio affected?
- No. Only the video stream is filtered, so the audio track is copied through untouched — no re-encoding and no quality loss on the sound.
- Are my files uploaded to a server?
- No. The processing runs on your device using WebAssembly and browser APIs. Your video is never sent anywhere, and the tool keeps working even if you go offline after the page loads.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Drop a file, pick a direction, and download the flipped result.
- Why does flipping take longer than muting?
- Flipping the picture requires decoding and re-encoding the video frame by frame, unlike a stream-copy. We pin the bitrate to your source so the re-encoded video keeps its quality. Shorter clips and lower resolutions finish faster.
