Mirror & Flip Image

This tool mirrors images — flips them left ↔ right, top ↔ bottom, or both at once — directly in your browser. It takes PNG, JPG, WebP, GIF, BMP and AVIF files, up to 50 at a time and 50 MB each, and never uploads them: each image is read into the page's memory, mirrored and offered back as a download.

Before you start, one honest note: the Rotate & Flip Image tool on this site already does a horizontal and a vertical flip, and it also turns an image 90° or 180° and straightens a tilt. This page is the dedicated mirror/flip URL — it does exactly the three flips here and nothing else, so it is the quicker choice when a flip is all you need. There is no rotation on this page, and it does nothing the rotate tool cannot.

Horizontal swaps left and right, like a reflection in a mirror: lettering and number plates come out reversed. Vertical swaps top and bottom, as if the picture were reflected in water. Both at once is identical to rotating the image 180° — the top-left corner ends up at the bottom-right. Mirroring moves each pixel to another whole pixel position with no averaging or interpolation, so nothing is blurred and no detail is softened. Applying the same mirror twice returns the original image, and the picture never changes size — a 4032 × 3024 photo stays 4032 × 3024 px.

The output format follows "Save as". PNG output is pixel-exact and lossless — the mirrored pixels are stored as they are. JPG and WebP cannot hold an exact copy, so those outputs are re-encoded at the quality you choose (92 by default): the flip is still whole-pixel, but the file is compressed again, so it is not byte-for-byte lossless. GIF, BMP and AVIF cannot be re-encoded by a browser canvas, so with "Same as input" they are saved as PNG; an animated GIF, WebP or AVIF keeps only its first frame. JPG has no transparency, so mirroring a transparent PNG to JPG fills the transparent areas with the background colour you pick (white by default).

How it works: your browser decodes each image with its own codecs, applying the photo's EXIF orientation first so you mirror the upright picture you can see, then draws it onto a canvas of the same size using one mirror transform and re-encodes it. The saved file carries no EXIF metadata — no camera, date or GPS location — because the picture is redrawn on the canvas.

Limits: 50 images, up to 50 MB each, and an output of at most 16,384 px per side and 100 megapixels. iPhones and iPads allow canvases of only about 16.7 megapixels, so very large photos may fail there with a message saying so. Your images stay on your device: the Network tab of your browser's developer tools shows no request carrying them.

1. Each file's size is checked (50 MB) before it is read, and its first bytes are checked to confirm it is PNG, JPG, WebP, GIF, BMP or AVIF — never the file name or the browser-reported type. 2. The direction is turned into a rotate-image orientation: Horizontal is the "flipH" step (0 turns, mirrored), Vertical is "flipV" (180°, mirrored), and Both is "flipH" then "flipV" — a 180° turn with no mirror. 3. A source pixel (x, y) of a w × h image lands at (w − 1 − x, y) for a horizontal mirror, at (x, h − 1 − y) for a vertical mirror, and at (w − 1 − x, h − 1 − y) for both — whole pixels, no interpolation. 4. The browser decodes the image upright (EXIF orientation applied) and one flip matrix is set on a canvas the same size as the source; the image is drawn once with smoothing off and the canvas is encoded, named like photo-mirrored.jpg.
