What is a horizontal flip?

The image is mirrored left-to-right, as if you held it up to a mirror.

Does flipping affect quality?

The default PNG output is lossless, so quality is unchanged. Choosing JPG re-encodes the image at quality 0.92.

Can I flip a JPEG without re-compressing it?

Yes, with the default output: the flipped image is saved as a lossless PNG, so the JPEG is not compressed again. Choosing JPG re-encodes it at quality 0.92.

Can I flip an image vertically instead?

Yes. Click Flip V in the tool to mirror the image top to bottom; the canvas then uses scale(1, -1) in place of scale(-1, 1).

How it works

The tool makes a canvas the same size as your image, moves the origin to its center with translate() and applies scale(-1, 1), which mirrors the x axis, so the left edge becomes the right and the size is unchanged. PNG output is lossless; JPG is encoded at quality 0.92 with transparent areas filled white.

Processing runs in your browser

All transformations are applied using the Canvas API inside your browser. Our servers are not involved at any point.
