Why flip videos?

Most people arrive here with a reversed recording rather than a creative idea. Webcams, front-facing phone cameras and screen-recording tools almost all show a mirrored image while you record, and a good number of them save it that way — so the text on your whiteboard reads backwards, the logo on your shirt is inverted, and you are gesturing towards the wrong side of the frame. Flipping horizontally undoes that in one step, and the frame keeps exactly the dimensions it started with.

Mirror video horizontally or vertically, or fold one half onto the other.

Flip left–right, upside down, or both at once. Flipping both ways into MP4 or MOV copies the picture instead of re-encoding it, so nothing is lost.

What flipping fixes

Reversed webcam and selfie footage: restore natural left–right orientation so text and logos read correctly.
Upside-down camera mounts: action cameras and dashcams clipped inverted record a usable picture the wrong way up.
Composition and eyelines: mirror a shot so a subject faces into the frame rather than out of it.
Symmetry effects: reflect one half of the picture onto the other for a kaleidoscope look.
Unchanged dimensions: a flip never resizes, crops or re-frames — width and height are exactly what they were.

Flipping both ways without re-encoding

Mirroring left–right and then top–bottom is not two operations — it is the same thing as turning the picture 180 degrees. That matters far more than it sounds, because MP4 and MOV files carry an orientation field that every correct player reads before it draws a frame. When you ask for both directions and choose one of those two formats, this tool writes 180 into that field and copies the compressed picture across untouched. Nothing is decoded, nothing is re-encoded, and the result is identical to your original file at the level of the individual video packets. Measured on a ten-second 1080p clip, that takes about 14 milliseconds; mirroring the same clip on one axis takes roughly two seconds, because every frame has to be decoded, reflected and encoded again.

When the copy is used

Both directions at once: the only flip that reduces to a plain 180-degree turn.
MP4 or MOV output: the two containers that carry an orientation field players actually honour.
A codec the container can hold: the compressed picture is moved across as-is, so it must be storable as-is.
No mirror-fold, and no request to write the orientation into the picture: either of those changes pixels by definition.

When the video is re-encoded, and what that costs

A single-axis mirror: a true reflection, which no container can express. Every frame is redrawn.
WebM or MKV output: neither carries an orientation field that can be relied on, so the turn goes into the picture.
Mirror-fold: half the frame is replaced by a reflection of the other half — a per-pixel change.
What it costs: the encoder is held to the bitrate your source already used, so the file does not grow and the picture stays visually very close. The tool says which of the two paths a run will take before you press anything.

Flip options

Four directions and a fold, and the preview shows the result before you commit to it. Drag the divider across the picture to put the original and the flip side by side on the same frame — on a broadly symmetrical shot that is the only reliable way to tell that anything happened at all.

The four directions

Horizontal (mirror): reflects left–right. The fix for reversed webcam and selfie footage, and what most people mean by "mirror".
Vertical: turns the picture upside down. Usually a fix for an inverted camera mount, or a deliberate effect.
Both: the 180-degree result, with the frame the same shape. This is the one that can be copied rather than re-encoded.
None: no mirroring — useful on its own only when you are writing an existing orientation into the picture, or folding.

Mirror-fold: making a frame symmetrical

The fold takes one half of the frame and reflects it onto the other, so the result is perfectly symmetrical about the centre line. Keeping the left half mirrors it rightwards; keeping the top mirrors it downwards. It is a creative effect rather than a correction, and it composes with the direction controls — you can mirror the clip first and then fold it, and the preview shows the combination rather than either step on its own.

What people use it for

Short-form social video: the symmetry effect that reads instantly on a small screen.
Music and visualiser content: a kaleidoscope look without an editor or a plugin.
Transitions: a folded frame cuts cleanly against an unfolded one.
Hiding one side of a shot: a distracting object on one half is replaced by a reflection of the other.
Unchanged dimensions: folding replaces content inside the frame; it never changes the frame's size.

How video flipping works

A flip is a permutation: every pixel in the result is a pixel from the source, moved to a different address and otherwise untouched. There is no resampling, no interpolation and no colour conversion involved, which is why a flip — unlike a resize or a rotation to an arbitrary angle — cannot soften a picture. What costs time is not the mirroring but the compression around it.

What happens to your file

Read: the container is parsed on your device and the video track's real dimensions and orientation are read from it — never guessed from the file extension.
Decide: the tool works out whether this particular combination of direction and output format can be copied rather than re-encoded, and tells you which before you start.
Copy, or redraw: either the compressed picture is moved across untouched, or each frame is decoded, mirrored and encoded again — in the background, so the page stays responsive.
Verify: the result is re-opened and checked before it is offered to you — real dimensions, a real duration, and, for a copied flip, video data identical to the source's.
Save: the file is written to your device. Nothing was uploaded at any point.

Best practices

A flip is easy to get subtly wrong, because the result looks entirely plausible either way. These are the habits that stop that happening.

Getting the best result

Use the preview divider before you download. A mirror is invisible on a symmetrical shot, and the side-by-side comparison is the only quick way to be certain.
Look for text. Any writing in the frame — a whiteboard, a sign, a T-shirt — tells you instantly which way round the picture is.
Choose MP4 or MOV when flipping both ways, so the picture is copied rather than re-encoded.
Match the source format when you can. Re-encoding into a different codec costs quality that flipping itself does not.
Flip once. Every re-encode of an already-encoded file loses a little, so going back and forth between orientations is worth avoiding.
Use the frame scrubber if your clip opens on black, so you judge the flip on a frame that actually has a picture in it.
Keep your originals until you have checked the result, especially when working through a batch.

Common use cases

Webcam and selfie corrections: reverse the mirroring your camera applied while recording.
Screen recordings and tutorials: make on-screen text readable again after a mirrored capture.
Inverted camera mounts: fix action-camera and dashcam footage recorded upside down.
Social publishing: mirror a shot so the subject's eyeline works with the layout around it.
Creative effects: mirror-fold a clip for symmetry, or flip vertically for a deliberately disorienting look.
Batch normalisation: bring a folder of clips to the same orientation and take them away in one archive.

How it works (technical overview)

Everything runs on your own device. The container is parsed locally, the picture is decoded by the same hardware path your video player uses, and the result is written back without a byte leaving the machine. The work happens in the background, away from the page, which is why the interface stays responsive on a long clip instead of freezing while a progress bar claims otherwise.

The steps in detail

Parse: the file's container is read and the video track's display dimensions, orientation and bitrate are measured from real packets.
Plan: direction, fold and output format together decide whether this run can copy the picture or must redraw it. The answer appears in the panel before you press anything.
Copy: for a both-ways flip into MP4 or MOV, a 180-degree orientation is written and the compressed picture is moved across untouched.
Redraw: otherwise each frame is decoded, mirrored and folded on a reusable drawing surface, then encoded at the rate your source already used.
Check: the finished file is re-opened and inspected. A flip that changed the frame's size, or a copy that turned out not to be one, is reported rather than handed over.
Deliver: the result is saved from your device, alone or as part of a ZIP of the whole batch.

Frequently asked questions

What is the difference between flipping and rotating a video?

Flipping mirrors the picture across an axis, like a reflection, and the frame keeps its width and height. Rotating turns the picture, and a quarter turn swaps width and height so a landscape clip becomes portrait. Flipping is what you want for a reversed webcam recording; rotating is what you want for footage filmed sideways. If you need to turn a clip rather than mirror it, use the rotate tool.

How do I fix a mirrored selfie or webcam recording?

Front-facing cameras and most webcam software show you a mirrored image while recording, and some save it that way. Choose the horizontal flip to reverse it — text in the shot becomes readable again, and the left-right orientation matches what other people see when facing you. If you are not sure whether a clip is mirrored, drag the divider across the preview: any text, logo or parting in someone's hair will make the answer obvious.

Does flipping a video reduce its quality?

It depends on which flip you choose. Flipping both ways is the same operation as a 180-degree turn, and MP4 and MOV can store that in the file's own orientation field — so the picture data is copied across untouched and the quality is identical to the original, byte for byte. A single-axis mirror is a genuine reflection that no container can express, so the video is re-encoded. In that case the encoder is held to the rate the source already used, so the result never grows and stays visually very close to the original.

Why is flipping both directions so much faster?

Because nothing is decoded. Mirroring left–right and then top–bottom is mathematically the same as turning the picture 180 degrees, and MP4 and MOV files carry an orientation field that every correct player reads. So the tool writes 180 into that field and copies the compressed video across as-is. On a ten-second 1080p clip that takes about 14 milliseconds against roughly two seconds for a single-axis mirror of the same file — and the copied version is bit-for-bit identical to what you started with.

When should I use horizontal versus vertical flip?

Use the horizontal flip to mirror left–right — the fix for reversed webcam, selfie and screen-share footage, and the one people mean when they say "mirror". Use the vertical flip to turn the picture upside down, which is far rarer and is usually either a creative choice or a fix for footage from an inverted camera mount, such as an action camera clipped upside down. Choose both when you want the 180-degree result while keeping the frame the same shape.

What is the mirror-fold option for?

It reflects one half of the frame onto the other, producing a symmetrical, kaleidoscope-like picture. Keeping the left half mirrors it onto the right; keeping the top mirrors it downwards, and so on. It is a creative effect rather than a correction, and it is popular for short-form social video, music visuals and transitions. The frame size does not change — only the content inside it.

Which video formats can I flip?

MP4, MOV, WebM and MKV, and you can output to any of those four. What matters is not only the container but the codec inside it, which is why the tool checks your file when you add it rather than guessing from the extension. Older formats such as AVI, WMV, FLV and 3GP cannot be opened on-device at all, so they are refused straight away with an explanation instead of failing partway through.

My video still looks sideways after uploading it somewhere. Why?

Phones record sideways footage as a normal landscape picture plus an orientation field, and while good players honour that field, some upload pipelines and social platforms ignore it. When you add a clip like that, the tool notices and offers to write the orientation into the picture itself. That produces a file that looks correct everywhere, at the cost of re-encoding it — which is exactly the trade the platform ignoring the field has forced on you.

Can I flip several videos at once?

Yes, on Pro. Free flips one video at a time, up to 200 MB and five minutes, with no watermark. Pro lifts the file count to twenty per batch and removes the size and length caps entirely — the ceiling becomes whatever your device can handle rather than a number we picked. A finished batch downloads as a single ZIP.

Are my files uploaded anywhere?

No. The video is read, flipped and written back on your own device, and it never leaves it. That is also why there is no queue, no waiting for a server and no watermark — there is no server involved in the work at all. It is why a large file is limited by your device's memory rather than by an upload allowance.
