Flip Image Online

Written by Blake Boege · Founder, Calculator Answers

An image flipping utility is a graphic editor that performs horizontal or vertical reflections on a 2D image matrix. Operating client-side, it modifies the canvas coordinate space using negative scaling matrices before drawing the source image, exporting the flipped pixels in their original format.

Quickly mirror your images horizontally or vertically. Safe, local browser-side transformation.

Upside-down flip

Standard landscape photo → Vertically flipped reflection

How it works

This tool mirrors images client-side using coordinate space transformations on an HTML5 canvas.

When an image is loaded, a canvas of the same dimensions is initialized. Before drawing, the context transform matrix is altered:

For horizontal flip: the context is translated to the right edge and scaled by -1 on the X-axis.
For vertical flip: the context is translated to the bottom edge and scaled by -1 on the Y-axis.

The image is then drawn, rendering a perfectly mirrored output which is converted directly into a downloadable data blob in the same format.

Instant & Secure. Your images are processed directly in your web browser. No files are uploaded or stored.

Frequently asked questions

Upload your PNG, JPG, or WebP file to the dropzone, choose the flipping direction (Horizontal to mirror left-to-right, or Vertical to flip upside-down), preview the result, and click the Flip Image button to download.

No. The entire mirroring process happens in your web browser using HTML5 Canvas. Your images are never sent over the network, ensuring complete privacy.

Flipping horizontally mirrors your image along the vertical axis (left becomes right, like looking in a mirror). Flipping vertically mirrors it along the horizontal axis (top becomes bottom, upside down).

No. The tool draws the original image pixels onto a scaled canvas, maintaining the original dimensions and resolution without quality degradation.
