Flip Image Online

When you take a selfie on a smartphone, the camera app often saves the image backward. If you're designing a website and need a hero image subject to look toward your call-to-action button, you need to mirror it. This tool lets you instantly flip photos without waiting for Photoshop to load.

How the Canvas Math Works

When you upload a photo, this tool draws it onto an invisible HTML5 <canvas>. To mirror the image horizontally, it applies a geometric transformation, literally scaling the X-axis by -1. This mathematically reverses every pixel's X-coordinate while keeping the Y-coordinate intact. It then renders the new pixel matrix so you can download it.

Total Privacy

Because this entire geometric transformation happens inside your local device's RAM using JavaScript, the image never leaves your computer. You can safely flip private selfies or confidential unreleased product photos without worrying about cloud server logs.

Flipping vs. Rotating

A lot of people confuse flipping with rotating. Rotating an image turns it 90 degrees like a steering wheel. Flipping an image creates a true mirror reflection. Keep in mind: if your photo contains text (like a t-shirt logo), flipping the image horizontally will cause the text to be completely backward and unreadable.
