Flip Image (Mirror Image)

A mirror flip swaps the left and right sides of a picture — the fix for selfies whose text reads backwards, for product shots that should face the other way, or for iron-on transfers that must be printed reversed. A vertical flip turns the image upside down without rotating it. This tool does both, exactly and in bulk, inside your browser.

How to use this tool

1. Choose one or more images.
2. Pick horizontal (mirror), vertical (upside down) or both.
3. Keep the original format or switch to JPG, PNG or WebP.
4. Download the flipped images, or all of them as a ZIP.

Formula

Horizontal: new(x, y) = old(W − 1 − x, y) · Vertical: new(x, y) = old(x, H − 1 − y)

Flipping both ways gives the same pixels as a 180° rotation. The flips are done with exact integer canvas transforms with smoothing switched off, so every pixel is copied unchanged; only re-saving a JPG introduces its usual tiny compression change.

Example

Mirroring a 1080 × 1350 px selfie keeps it at 1080 × 1350 px; the pixel that was at the far right edge, x = 1079, moves to x = 0. Text on a T-shirt that read backwards in the front-camera photo now reads correctly.
