FREE IMAGE MIRROR TOOL

Flip an Image Online

Mirror a picture horizontally or vertically while keeping its original dimensions. The transformation happens locally and the result is ready to download immediately.

Photo dimensions & file-size quick reference

Dimensions are width × height in pixels. Suggested file sizes are compression targets, not platform limits.

Need another shape? Crop first, then resize and compress. Keep your original; do not sacrifice detail just to reach a suggested target. JPG is usually suitable for photos. Etsy does not preserve PNG transparency.

Etsy and Pinterest guidance was checked on this date.

Check the destination’s uploader for its current limit: posting apps, advertising tools and APIs may have different requirements.

How to use this tool

1

Choose an image

Select a JPG, PNG or WebP file from your device. The file stays in your browser.

2

Set the options

Choose the values required for the destination where you will use the image.

3

Process and download

Check the result, then download the new copy to your device.

Horizontal vs vertical flip

A horizontal flip exchanges the left and right sides, like a mirror. A vertical flip exchanges the top and bottom.

Flipping preserves width, height and the complete frame. Text and logos will also be reversed, so inspect the preview before downloading.

Common uses

Mirror a selfie

Reverse left and right when a front-camera photo appears unfamiliar.

Adjust direction

Make a subject face toward page text or another design element.

Correct scans

Repair an image scanned from the reverse side or with the wrong orientation.
