What does inverting an image mean?

Inverting replaces each color with its opposite. Every color value from 0 to 255 becomes 255 minus itself. White turns black, black turns white, red turns cyan, blue turns yellow and a mid gray stays almost the same. The result looks like a photographic negative.

People invert images to read light text on a dark page more comfortably, to make a dark logo work on a dark background, to read a scan of a film negative, to find faint details in a very dark or very bright picture and to create a bold graphic effect.

The tool changes only the color channels. The shape, size and transparency of the picture do not change, so a PNG with a see-through background keeps its edges.

Strength, formats and transparency

At 100 percent the colors are fully inverted. Lower values blend the negative with the original. At 50 percent most colors collapse to a flat gray, which is a good way to see the idea in action, while around 20 to 30 percent gives a faded, filmic look.

PNG, WebP and AVIF files with transparency keep their alpha channel exactly as it was. Only the visible colors are inverted, so a cut-out logo stays cut out. JPG and WebP files are saved again at quality 92 by default, and you can choose another output format and quality in the options.

• Strength 100 gives a true negative.
• Output format can stay the same, or switch to JPG, PNG or WebP.
• Phone photos are turned upright before inverting. Location and camera data are removed.

Useful ways to use a negative

Scanned film negatives look orange and dark. A simple invert shows the picture in its true shape, and you can then adjust it in a photo editor. For black and white negatives the result is immediately readable.

For screenshots, an inverted copy of a white document gives a dark mode version you can read at night. Diagrams drawn in black on white can be made white on black for a slide with a dark theme.

In astronomy and medical imaging, a negative view often makes faint bright points easier to spot against a dark background.

Invert an image on iPhone, Android and computers

On an iPhone the Photos editor has no invert button, and the Accessibility invert only changes the screen, not the file. This page creates a real inverted file. Open it in your browser, tap Choose files and select photos. HEIC files should be converted to JPG first.

On a computer, drag your pictures onto the box or paste one. The preview is instant, and the full size file is made when you press the button.
