Flip picture horizontally or vertically

How to flip an image

Choose an image from your device; the Original preview appears once it decodes. Tick Horizontal flip, Vertical flip, or both, then select Flip image. The Result preview appears beside the Original, or below it on a narrow screen, and Download PNG saves a PNG with the same width and height as the source.

Every export starts fresh from the original decoded image, so flipping again after already flipping does not add a second flip on top of the first. Reset flips returns both checkboxes to their unticked state. With neither box ticked, Flip image still runs and exports an unflipped PNG copy. There is no drag-and-drop area on this page; select the file through Choose image or Replace image.

1. Choose an image from your device.
2. Tick Horizontal flip, Vertical flip, or both.
3. Select Flip image and compare the Original and Result previews.
4. Select Download PNG.

Horizontal, vertical or both

Horizontal flip swaps left and right like a mirror, which also reverses any text visible in the image. Vertical flip swaps top and bottom. Ticking both together produces the same pixel arrangement as rotating the image 180 degrees, though this tool performs it as a flip, not a rotation.

Each flip is a single 2D canvas transform applied once to the original decoded image, so choosing a direction and exporting, then choosing a different direction, always starts over from the same source pixels rather than compounding onto the previous export. Horizontal flip sets the canvas's horizontal scale to -1, vertical flip sets its vertical scale to -1, and ticking both applies both scale factors in the same transform. None of the three choices changes the width or height, because a mirror only moves pixels to new places.

What flipping changes

Mirroring moves decoded pixels without resizing or interpolation, so the width and height in the result always match the source exactly, after the browser applies the source's own orientation first. The export step re-encodes the mirrored canvas as a Portable Network Graphics (PNG) file, so the output's byte size usually differs from the input even though no pixels were resampled.

The download is a new PNG made from the decoded pixels. It carries no EXIF or other metadata from the source, and an animated GIF or WebP gives 1 still frame. The flip does not recolor anything, but the browser canvas can round the color of partly transparent pixels. The Preview & download panel states this directly: dimensions stay the same, transparency is retained, and the PNG output can be larger than the source file, since flipping is not a compression step.

Limits

While the tool works, Cancel & clear stops it. Once a result exists, the same button reads Clear image and removes the picture so you can choose another. A damaged or unsupported file shows an error and asks for another image. The Original preview is scaled to at most 1200 pixels on its longer side; the Result preview and the download always keep the full source size.

The largest image you can flip depends on your browser's memory and canvas limits. A file that fails to load shows an error and asks you to choose another image; only an export failure keeps your current image and settings. If the export fails, the page keeps your image and names the size it could not create, so you can try a smaller image or another browser. You flip one image at a time, since there is no batch queue for several files at once.
