Common uses for flipping a video
Every case below is solved with a single mirror flip — no professional editing software needed.
Undo the selfie mirror from a phone's front camera
On most phones the selfie you see on screen is mirrored, yet the saved video is sometimes un-mirrored, so it looks left-right reversed compared with what you are used to. One horizontal flip switches it back to the version you want — check the preview before you post.
Mirror portrait videos for TikTok and Douyin
Short-video creators often use a horizontal mirror to change how a shot feels, or to make reused footage look different from the original. Flipping a portrait video leaves resolution and duration untouched, so it uploads normally and still meets each platform's aspect-ratio rules.
Fix upside-down security-camera and dash-cam footage
When a camera is mounted upside down on a ceiling or windscreen, the recording comes out inverted. A vertical flip turns the picture right side up; if it is also left-right reversed (shot through a mirror, for example), add a horizontal flip.
Mirror tutorials and workout videos for easy follow-along
In yoga, dance and instrument lessons, mirroring the demonstration means that when the viewer raises their left hand, the person on screen raises theirs too. No mental left-right translation is needed, which makes the lesson far easier to follow.
Create mirror-symmetric visual effects
Place a flipped copy next to — or before and after — the original to build symmetrical compositions or a "twin" appearance. Flip the clip here, then finish the effect with the video merger.
Fix reversed screen casts, re-shoots and screen recordings
Footage captured through a projector, a mirror or certain capture cards occasionally comes out left-right reversed, with all the text backwards. A single horizontal flip restores normal reading direction — no need to record again.
Horizontal or vertical flip — which one should you pick?
The two directions solve completely different problems, so start by identifying which one you actually have.
| Flip Direction | What changes | Best Use Case |
|---|---|---|
| Horizontal flip (left-right mirror) | Reflected across the vertical axis, left becomes right — exactly like a mirror | Undoing a selfie mirror, mirroring tutorials for follow-along, reworking short-video footage. This is by far the most-used direction. |
| Vertical flip (top-bottom mirror) | Reflected across the horizontal axis, top and bottom swap and the picture looks hung upside down | Fixing upside-down footage from inverted cameras, drones or dash cams, plus reflection-style creative effects. |
Note: neither flip changes the resolution, duration or frame rate of your video — only the direction in which pixels are arranged. If what you need is to turn the whole picture 90° or 180° (landscape to portrait), that is rotation rather than flipping; see the comparison in the next section.
Flipping vs rotating a video: what is the difference?
This is the pair people mix up most often: flipping is a mirror reflection, rotating is a turn through an angle. Pick the wrong one and the picture will not end up the way you want.
Video flip (this tool)
The picture is mirrored across a central axis. Width and height stay the same, but left and right (or top and bottom) are swapped and on-screen text reads backwards. Use it when the orientation simply feels reversed.
Rotate Video
Turns the whole picture by 90°, 180° or 270° without mirroring, so text stays readable; a 90° rotation swaps the video's width and height. Use it when the picture is lying on its side or upside down.
| Comparison | Flip (mirror) | Rotate |
|---|---|---|
| Text in the picture | Reads backwards and is hard to read | Stays readable, only the direction changes |
| Video dimensions | Always unchanged | Width and height swap at 90° / 270° |
| Typical problem | Selfie looks left-right reversed; follow-along moves do not match | Phone footage lies on its side or appears upside down |

About the Video Flipper
VideoKit's Online Video Flipper is built on WebCodecs technology, letting you mirror videos right in your browser. It supports horizontal flip (left-right mirror) and vertical flip (up-down mirror), with a real-time preview so you can see the result before processing. Everything runs locally — your video files are never uploaded to a server, keeping your data private. Supports MP4, WebM, MOV, and other popular video formats for both input and output.
If you need to change the angle of the picture rather than mirror it, use the video rotator; to keep only part of the frame, use the video cropper; to change the overall resolution, use the video resizer.

Frequently Asked Questions
What's the difference between horizontal and vertical flip?
Horizontal flip swaps left and right, like a mirror image. Vertical flip swaps top and bottom, turning the image upside down. Choose whichever matches your needs.
What is the difference between flipping and rotating?
Flipping is a mirror operation: the picture is reflected across an axis, dimensions stay the same but left and right (or top and bottom) are swapped, so text reads backwards. Thevideo rotatorturns the whole picture by an angle instead, without mirroring it, and swaps width and height at 90°. Use flip to undo a selfie mirror, and rotate to change landscape into portrait orientation.
Will flipping affect video quality?
By default we use high-quality encoding parameters, so quality loss is minimal and typically invisible to the naked eye. The flip requires re-encoding the video to properly apply the mirror effect.
Will my video files be uploaded?
No. All video processing happens locally in your browser. Files are never uploaded to any server, and your video data stays entirely under your control.
Does the flipped video have a watermark? Do I need to pay or sign up?
No watermark, completely free, and no account or plugin is required. There is no limit on how many videos you flip — just open the page and start.
Which video formats are supported?
Reads most common video formats (MP4, WebM, MOV, MKV, AVI, and more) and outputs in MP4, WebM, or MOV. For the best compatibility, we recommend a recent browser (Chrome or Edge).
The text in my video reads backwards after a horizontal flip. What should I do?
That is inherent to mirroring: text, signs and license plates all read backwards after a horizontal flip. If the source was recorded with a front-facing camera and is already mirrored, flipping actually restores the text to its normal direction. If the text was correct to begin with, flipping will reverse it — in that case what you most likely need is rotation, not a flip.
Can I flip a video on my phone?
Yes. The tool works in mobile browsers (iOS Safari 16+ and Android Chrome) with no app to install. Phones are limited by memory on large files, so compress the video first or switch to a desktop browser.
Can I flip horizontally and vertically at the same time?
Each run applies one direction. If you need both (which is the same as a 180° rotation), re-upload the result of the first flip and flip it again — or simply use the video rotator and pick 180°.
Can I flip several videos at once?
The flipper handles one video at a time. Because everything runs locally in your browser, processing files one by one avoids the memory pressure that would otherwise cause failures. For a batch, finish one file before uploading the next.
What's the maximum video file size?
Keep files under 2 GB for the best performance. All processing happens inside the browser, so speed depends on your CPU and memory; for long videos, use desktop Chrome or Edge.
Does flipping change the video's resolution or duration?
No. A mirror flip only changes the direction in which pixels are arranged — resolution, duration, frame rate and the audio track all stay as they were. If you need to change the resolution, use the video resizer instead.
