Need to flip or mirror a video without uploading it to the cloud? Our free online video flipper mirrors MP4, MKV, MOV, AVI, and more — directly in your browser. Flip horizontally to fix mirrored selfie footage, flip vertically to correct upside-down clips, or flip both axes for a 180° rotation. No file ever leaves your device. Powered by FFmpeg WebAssembly, it delivers clean results with zero privacy risk.

§02 — Flip Modes Explained

Choose how to mirror your video. Each mode applies an FFmpeg flip filter and re-encodes to a clean MP4 you can play and share anywhere.

HFLIP

Flip Horizontally

Mirrors the video left to right using the hflip filter. This is the most common flip — it corrects the mirror effect on front-camera and webcam recordings so text and logos read the right way around.

VFLIP

Flip Vertically

Mirrors the video top to bottom using the vflip filter. Useful for footage captured upside down, mounted cameras, or reflections shot through glass or water.

HFLIP,VFLIP

Flip Both Axes

Applies hflip and vflip together, which is equivalent to rotating the video 180°. Ideal when a clip was recorded completely inverted on a gimbal or mounted rig.

§03 — When Should You Flip a Video?

Flipping fixes orientation problems that re-recording can't, and it unlocks creative mirror effects.

Fix Mirrored Selfie Footage

Front-facing cameras record a mirrored image, so text and gestures appear reversed. A horizontal flip restores the natural orientation that viewers expect.

Creative & Social Edits

Mirror a clip to create symmetry effects, match a duet's framing, or correct an upside-down clip before posting to TikTok, Instagram, or YouTube Shorts.

§04 — Why Local Flipping Beats Cloud Services

Cloud flippers make you upload your entire video, wait in a queue, then download. Our local-first approach eliminates all of that.

Privacy: Your videos never leave your device — essential for personal, confidential, or sensitive footage.
Speed: No upload queue. Flipping starts the instant your file loads.
No Daily Limits: Flip videos as many times as you like without queues or credits.
§05 — Zero-Upload Privacy

All video flipping happens inside your browser using WebAssembly-compiled FFmpeg. No video data ever touches our servers. There is no cloud processing, no tracking, no server logs. Close the tab and every trace is gone — your footage remains yours alone.

§06 — How to Flip a Video

§09 — Frequently Asked Questions
Yes — our video flipper is completely safe. All processing happens locally in your browser using FFmpeg WebAssembly. Your video files are never uploaded to any server, so they remain fully private and secure.
Flipping mirrors a video across an axis, producing a reversed (mirror) image — like looking in a mirror. Rotating turns the frame by an angle (90°, 180°, 270°) without mirroring. Flipping both horizontally and vertically happens to look identical to a 180° rotation, but a single horizontal or vertical flip is a true mirror, not a rotation.
Front cameras record a mirrored preview, so the saved video can look reversed. Upload it here, choose Flip Horizontally, and download the corrected MP4. Text, logos, and gestures will read the right way around.
You can flip MP4, MKV, WebM, AVI, MOV, WMV, FLV, 3GP, MPEG, OGV, and M4V files. The output is always an MP4 (H.264) file, which plays on every device and platform.
Flipping requires re-encoding the video, which involves a minor quality tradeoff. We encode with a high-quality setting (CRF 18, near-lossless), so the difference is imperceptible on a normal screen. Audio is preserved and re-encoded to AAC.
Yes. The audio track is preserved and re-encoded to AAC inside the MP4 container, so your sound plays back exactly as before. Flipping only affects the video frames, never the audio.
Because all processing happens in your browser, there is no server file size limit. Very large files (over 2GB) may require significant RAM and time. For best performance, files under 500MB and a desktop browser are recommended.
Yes. Chrome on Android handles moderate-size clips well, and iOS Safari works too, though WebAssembly is slower on mobile. For long or high-resolution videos, a desktop browser will flip faster.
The flipped output is always an MP4 file encoded with H.264 video and AAC audio. MP4 is the most universally compatible format — it plays on every device, browser, and platform without extra software.
Never. There are no watermarks, no logos, and no quality limits. The flipped MP4 you download contains only your footage, mirrored exactly as you chose.
