Image colour inverter
Settings
No settings needed. Every colour is replaced by its opposite (white ↔ black, blue ↔ yellow); transparency is kept.
How to
Invert the colours of an image.
- 1Choose your images, or drop them on the box.
- 2Each one is inverted straight away; the result is shown next to it.
- 3Download each image, or Download all as a ZIP.
How it works
Every colour becomes its opposite.
Each of red, green and blue is replaced by 255 minus its value. Transparency is left alone, so a logo on a transparent background stays on a transparent background.
| Colour | Inverted |
|---|---|
#000000 black | #FFFFFF white |
#0000FF blue | #FFFF00 yellow |
#FF0000 red | #00FFFF cyan |
#39FF14 green | #C600EB purple |
Uses: a dark version of a light logo, reading a scanned film negative, or checking contrast. Inverting twice gives back the original.
FAQ
Questions people ask first.
- How do I invert the colours of an image?
- Open it in the tool above; it is inverted straight away. Download the result.
- Can I turn a film negative into a positive?
- Inverting gets you most of the way. Colour negatives also have an orange base, so the result may need a colour correction afterwards in an editor.
- Is transparency kept?
- Yes. Only the colours are inverted; see-through areas stay see-through in PNG and WebP.
- How do I invert a colour code?
- Subtract each pair of digits from FF. For example #39FF14 becomes #C600EB. Use the image colour picker to read codes from a picture.
- Are my images uploaded?
- No. Everything happens in your browser on your own device. Nothing is sent to Daniotech or anyone else.
