How to flip an image
- Add your images to the dropzone, or press Browse files to select them.
- Turn on Flip horizontal to mirror left to right, or Flip vertical to mirror top to bottom.
- Enable both if you want the equivalent of a 180 degree rotation.
- Press Flip images and let the batch finish.
- Download each result, or take the whole set as a ZIP archive.
What this tool does
- Mirrors in either axis, or both at once, with a single toggle each.
- Applies the same flip across twenty files, which suits scanned film and contact sheets.
- Rewrites the pixels rather than applying a CSS transform, so the change is permanent.
- Preserves the exact dimensions, flipping never resizes or crops anything.
- Keeps PNG transparency and lets you set JPG quality when that is the output.
- Discards the metadata block, removing camera details and GPS coordinates.
What flipping actually does to a picture
A flip mirrors the image across an axis. Horizontal flipping swaps left and right, so a subject looking to the left now looks to the right. Vertical flipping swaps top and bottom, producing the effect of a reflection in still water. Applying both is geometrically identical to rotating the image by 180 degrees.
Unlike rotation at an arbitrary angle, flipping is lossless in geometry. Every pixel moves to a mirrored position; none are created, blended or discarded. The only quality change comes from re-encoding the file afterwards, which is why the quality slider matters for JPG output and not at all for PNG.
When people need this
- Selfies. Front cameras preview a mirrored image but often save the unmirrored one, so the photo looks subtly wrong compared with what you saw.
- Scanned film and negatives. Load a strip the wrong way round and every frame comes out mirrored, including any text in shot.
- Design layouts. A subject facing out of the page pulls the eye away; flipping turns them back into the text.
- Transfers and printing. Iron-on transfers and some screen-printing processes require a mirrored source so the applied result reads correctly.
- Symmetry work. Flipping a copy and joining it to the original produces a mirrored composition.
Check the picture for text before you flip
This is the mistake worth avoiding. Any writing in the frame. A shop sign, a book cover, a logo on a shirt, a watermark, becomes unreadable when mirrored, and the result looks obviously wrong even to someone who cannot say why.
The same applies to anything the viewer knows the handedness of: a wristwatch on the wrong arm, a steering wheel on the wrong side, a guitar strung backwards. If the frame contains one of those, either accept it or crop the element out with the image cropper before flipping.
Flipping is not rotating
The two are often confused, and they produce different results. Rotation turns the image around its centre while preserving handedness. A rotated photograph is still the same scene viewed from a different angle. A flip reverses handedness, producing a mirror world.
If your photograph is sideways rather than mirrored, rotation is what you want, and the rotate image tool handles quarter turns and free angles. Flipping a sideways photo will simply give you a mirrored sideways photo.
Batch work and privacy
Because the transformation is identical for every file, flipping genuinely suits batches in a way that cropping does not. A whole roll of incorrectly scanned negatives can be corrected in one pass.
Everything happens on a canvas inside your browser, so no file is uploaded and nothing is stored anywhere. If you want the results smaller afterwards, the image compressor takes the batch straight from here, and the image resizer handles dimensions.
