Flip Video

About Flip Video

Quickly flip your videos horizontally (mirror effect) or vertically with our Free Online Flip Video Tool. This tool operates entirely within your web browser using FFmpeg.wasm, meaning your video files are processed directly on your device and are never uploaded to any server. Your privacy is guaranteed.

Simply upload your video, select whether you want to flip it horizontally or vertically, and click 'Flip Video'. You can preview both the original and the flipped result before downloading the modified video. The original audio track is preserved in the flipped video.

Features:

• Client-Side Processing: Uses FFmpeg.wasm for secure, in-browser video flipping. Your files stay private.
• Multiple Video Formats: Supports common video types like MP4, WEBM, MOV, AVI (depending on browser & FFmpeg support).
• Horizontal Flip: Creates a mirror image of your video.
• Vertical Flip: Flips your video upside down.
• Audio Preservation: Keeps the original audio track in the flipped video.
• Dual Preview: See your original video and a preview of the flipped version side-by-side (after processing).
• Easy Download: Download the flipped video directly to your device (output as MP4).
• Progress Tracking: Monitor the flipping process with a real-time progress bar.

How to Use:

1. Load Engine: Wait for the video processing engine (FFmpeg) to load (progress bar shown).
2. Upload Video: Drag and drop your video file onto the upload area or click "Select Video" to browse your device.
3. Preview Original: Your uploaded video will appear in the "Original Video" preview player.
4. Choose Flip Direction: Select either "Horizontal Flip" or "Vertical Flip" using the radio buttons.
5. Flip: Click the "Flip Video" button.
6. Wait & Preview: The progress bar will show the flipping status. Once complete, the flipped video (with audio) will appear in the "Flipped Video Preview" player. Any errors will be displayed in the status area.
7. Download: Click the "Download Flipped Video" button to save the result.
8. Share (Optional): Click "Share Tool" to share the tool's link.

Note: Video processing happens entirely in your browser. Flipping larger or longer videos may take more time and consume more system resources (CPU/Memory).

Quick Answer

To flip a video online, upload it to this page, choose Horizontal Flip (mirror) or Vertical Flip (upside down), click Flip Video, and download the MP4. The whole job runs inside your browser through FFmpeg.wasm, so the file never leaves your device, there is no watermark, no sign-up and no file-size cap other than your own device memory. A horizontal flip is what you need to un-mirror a selfie video or a webcam recording; a vertical flip is used for reflection effects and for footage that was recorded upside down.

Common Use Cases

Un-mirroring selfie and webcam video

Front-facing phone cameras and most webcams record a mirrored image, so any text, logo or number in the frame reads backwards. A single horizontal flip puts the scene back the way viewers actually saw it.

Fixing footage shot upside down

Action cameras and drones mounted upside down produce inverted clips. A vertical flip (or a 180° rotation) corrects the frame without re-shooting.

Beating duplicate-content detection on social platforms

Creators often mirror a clip before re-posting to TikTok, Instagram Reels or YouTube Shorts so the upload is not flagged as an exact duplicate of an existing video.

Choreography, sports and instruction videos

Mirroring a dance, golf swing or yoga demonstration lets a viewer follow along on the same side as the instructor instead of mentally reversing every move.

Design and motion-graphics work

Flipping a clip changes the direction a subject faces so it looks into the frame rather than out of it, which balances split-screen and picture-in-picture layouts.

Frequently Asked Questions

How do I flip a video horizontally?

Upload your video to this page, select the Horizontal Flip option, and click Flip Video. The tool applies the FFmpeg hflip filter, which mirrors every frame from left to right. When processing finishes, preview the result and click Download Flipped Video.

What is the difference between flipping and rotating a video?

Flipping mirrors the frame across an axis, so the content is reversed but the width and height stay the same. Rotating turns the whole frame by 90, 180 or 270 degrees, which swaps width and height for 90 and 270 degree turns. Use flip to correct a mirrored selfie, and rotate to fix video shot in the wrong orientation.

Is my video uploaded to a server?

No. This tool runs FFmpeg compiled to WebAssembly (FFmpeg.wasm) directly in your browser tab. Your video file is read from local storage into browser memory, processed on your own CPU, and the result is written back to your device. Nothing is transmitted to miniwebtool or to any third party.

Does flipping a video reduce quality?

The flip operation itself is a lossless pixel rearrangement, but the output must be re-encoded to MP4 (H.264), so a small generation loss is possible. In practice the tool uses a high-quality encoding setting and the difference is not visible at normal viewing sizes. The resolution, frame rate and duration are unchanged.

Which video formats are supported?

Common formats work, including MP4, WEBM, MOV and AVI, subject to what FFmpeg.wasm and your browser can decode. The output is always MP4 with H.264 video, which plays on virtually every phone, computer and social platform.

Is the audio kept when I flip a video?

Yes. The original audio track is preserved and stays in sync with the picture. Flipping only affects the video stream.

Is there a file-size or length limit?

There is no artificial limit, but processing happens in browser memory, so very large or very long files can exhaust the tab's memory. Clips up to a few hundred megabytes work reliably on a modern desktop; on a phone, keep files smaller and close other tabs first.

Is it free, and is there a watermark?

The tool is completely free, requires no account, and adds no watermark to your video.
