What Image Flipper does
Flipping is the only geometric operation on an image that is exactly, provably lossless. Every pixel keeps its value and simply moves to a mirrored position — the leftmost column becomes the rightmost, and nothing in between is recalculated. Flip twice and you have the file you started with, bit for bit.
That makes it trivial technically and entirely a question of judgement in practice. There is exactly one situation where mirroring is unambiguously wrong, and it is text: any writing in the image becomes reversed and unreadable, and no amount of adjustment fixes it short of flipping back.
When to use it
- Selfies that look wrong
- A phone shows you a mirrored preview but saves the unmirrored image, so the photo looks subtly unlike the face you were looking at. A horizontal flip restores what you saw.
- Making a symmetrical pair
- Two copies of an icon or ornament, one flipped, face each other correctly — a common need in layout and design work.
- Correcting a scan or a photo of a negative
- Film photographed or scanned from the wrong side produces a mirrored image. Flipping puts it right, though any text will confirm which way round it should be.
- Changing the direction of a subject
- A person or object facing out of a layout can be turned to face into it, which is often the difference between a composition working and not.
Image Flipper settings explained
- Horizontal
- Mirrors left to right, the flip people almost always mean. This is what corrects a selfie and what reverses the direction a subject faces.
- Vertical
- Mirrors top to bottom, turning the image upside down as a reflection rather than a rotation. Note this is not the same as rotating 180 degrees — a vertical flip reverses only one axis.
- Both together
- Applying both axes is equivalent to rotating the image 180 degrees, since reversing both directions is the same as turning it around.
- No quality setting
- There is nothing to configure because nothing is recalculated. Pixels are rearranged, not resampled, so the operation is exactly lossless regardless of format.
Flipping compared with rotating
| Operation | Result on a face | Text stays readable | Lossless |
|---|---|---|---|
| Horizontal flip | Mirrored | No | Yes |
| Vertical flip | Upside down and mirrored | No | Yes |
| Both flips | Same as 180° rotation | No | Yes |
| Rotate 180° | Upside down, not mirrored | No | Yes |
Limits and what to expect
- Any text in the image becomes reversed and unreadable — this is the one case where flipping is simply wrong.
- Logos, signage and number plates in a photo will read backwards.
- Flipping does not change file size or quality, since nothing is re-encoded beyond the format's own step.
- 50 files per batch, 100 MB each, 300 MB per queue.
- Animated GIFs lose their animation; only the first frame is flipped.
Troubleshooting
- The text in my image is backwards
- That is what mirroring does, and nothing can correct it while the flip is applied — flip back, or crop the text out and place it separately. It is the reason to check an image for signage and writing before flipping it.
- Flipping vertically did not do what I expected
- A vertical flip is a mirror across the horizontal axis, not a rotation. If you wanted the image the right way up but turned around, use the rotator at 180 degrees instead.
- The selfie still does not look right
- You are probably seeing the difference between the mirrored preview your phone showed and the unmirrored image it saved. A horizontal flip restores the mirrored version — the face you are used to seeing, rather than the one others see.
- The file size changed slightly
- The pixels are identical but the file is re-encoded on save, and a lossy format compresses the mirrored arrangement fractionally differently. Save as PNG if you need the file to be byte-identical in size.
Your files and your privacy
Flipping happens on a canvas inside your browser tab, on your own device. No image is uploaded, and batch ZIPs are assembled locally. The tool works with the network disconnected.

FAQ
Does flipping an image reduce quality?
No, and it cannot. Pixels are rearranged into mirrored positions without any value being recalculated — there is no interpolation, unlike rotating by an arbitrary angle. Flipping twice returns exactly the image you started with.
What is the difference between flipping vertically and rotating 180 degrees?
A vertical flip mirrors across the horizontal axis, so the image is upside down and reversed. A 180-degree rotation turns it around without mirroring. Applying both a horizontal and a vertical flip is what equals a 180-degree rotation.
Why does my selfie look wrong until I flip it?
Your phone shows a mirrored preview while you frame the shot — the face you see in a mirror — but saves the unmirrored image, which is how other people see you. Flipping horizontally gives you back the version you were looking at.
Can I flip an image with text in it?
You can, but the text will read backwards and there is no way to fix that while the flip is applied. Check for signage, logos and writing before flipping — it is the single situation where mirroring is simply the wrong operation.
Can I flip several images at once?
Yes, up to 50 within 300 MB. They all receive the same flip and download together as a single ZIP.
Are my images uploaded?
No. The flip happens on a canvas in your browser, on your own device, with no network request.
