    About Invert Image Colours

    When is it useful? Invert Image Colours creates a negative: white becomes black and every colour becomes its opposite. It is used to view old film negatives as positives, to create dark versions of diagrams, and for art effects.

    Good to know: only the colours are inverted — transparent areas stay transparent, so a logo on a transparent background keeps its shape. Inverting twice gives back the original picture. The result is saved as a PNG file.

    Example: you have a black diagram on a white background but your presentation uses a dark theme. Inverting gives a white diagram on black that fits the slides; invert it again any time to get the original colours back.

    Tips for Better Results

    • To turn a scanned film negative into a photo, invert it and then adjust brightness and contrast.
    • For black-on-white diagrams, inverting gives a white-on-black version for dark slides.
    • Invert a PDF instead with Invert PDF Colours.

    Invert Image Colours: a complete guide

    What inverting means

    Inverting replaces every colour with its opposite: black becomes white, white becomes black, blue becomes orange, and green becomes magenta. The result is a negative image, like the film negatives used in traditional photography.

    How it works

    Each pixel's red, green and blue values are subtracted from the maximum, while the transparency channel is left alone — so a logo on a transparent background keeps its exact shape. The picture keeps its size and is saved as a PNG. Inverting twice returns the original colours exactly.

    Practical uses

    Turn scanned film negatives into positive photos, make white-on-black versions of diagrams and signatures for dark slides or websites, create bold artistic effects, and check fine details in X-ray-style or technical images.

    Common problems and how to fix them

    A scanned colour negative still looks orange: colour film has an orange mask, so inverted negatives need extra colour correction in a photo editor. A logo became hard to see: inverted colours suit dark backgrounds — check where it will be used. You wanted to invert a whole PDF: use Invert PDF Colours.

    Good habits

    Keep the original, invert copies, and preview the result on the background where it will appear.
