About the Invert Image Colors
Invert Image Colors turns a picture into its colour negative. Every red, green and blue value is replaced by its opposite, so white becomes black, dark becomes light and each colour becomes its complement: blue turns yellow and red turns cyan. Use the slider to invert only part of the way for a softer effect. It works on photos, screenshots, scans of film negatives, line art and logos, and it keeps transparency in PNG files. Drop in one picture or many, and download the results one by one or as a ZIP. Everything runs in your browser.

How inversion works
Each pixel has three colour values from 0 to 255. Inverting subtracts each value from 255. A pure white pixel (255, 255, 255) becomes black (0, 0, 0). A bright blue becomes a dull yellow. The brightness pattern reverses, which is why the result looks like a photographic negative.
Useful ways to use it
Inversion has practical uses as well as artistic ones. It can make faint details in a scan easier to see, turn white drawings on black paper into black on white, and create a dark version of a diagram.
- Scan film negatives and invert them
- Make black line art white, or the other way round
- Test how an icon looks on a dark background
- Create striking art from a photo
Partial inversion
Between 0% and 100% the colours slide towards grey. This gives a washed-out look and can make a picture a quieter background for text. Try 70% or 30% and compare.

Frequently asked questions
What does inverting colours do?
It replaces each colour with its opposite on the colour wheel, so the picture looks like a photographic negative.
Can I turn a film negative into a normal photo?
Inverting a scan of a black-and-white negative gives the positive picture. Colour negatives have an orange tint, so you also need to correct the colours afterwards.
How can I make a dark mode version of a screenshot?
Inverting a mostly white screenshot makes it dark. Colours in photos and icons also flip, so check the result.
What does the slider do?
At 100% every colour is fully inverted. At 50% every colour becomes mid-grey. Values below that give a faint inversion.
Is transparency kept?
Yes, in PNG files. Choose PNG to keep transparent areas.
Can I undo it?
Inverting a picture twice returns the original colours, so you can run the result again to go back.
Is the file size the same?
Roughly. PNG sizes can change, and JPG files are saved again at a high quality.
Can I invert only part of a picture?
Not in this tool. It changes the whole image. To change only one colour, use the Replace Color in Image tool.
Why do skin tones look strange after inverting?
Inversion flips every colour to its opposite, so faces look blue-green. That is how a colour negative looks.
Can I use it on a scanned drawing?
Yes. Dark lines on white paper become white lines on black, which is useful for chalkboard-style art.
Are my pictures uploaded?
No. They are changed on your device.
