Invert an image in one step
The negative effect replaces every colour with its opposite on the colour wheel and every brightness with its reverse. It is useful for design effects, for checking contrast, for making dark-mode versions of diagrams, and – most often – for viewing old film negatives you have photographed with a phone.
Turning a film negative into a photo
- Light the negative from behind. Lay it on a phone or laptop screen showing a plain white page.
- Photograph it straight on. Fill the frame and avoid reflections.
- Add the photo here and convert. Black-and-white film looks right straight away. For colour film, adjust the colours afterwards in a photo app – the orange film base turns blue when inverted.
Need it in black and white too? Pick “Grayscale” or “Black & white” in the effect switch, or use the black and white converter.
Frequently asked questions
How do I view an old film negative?
Photograph or scan the negative on a light source (a phone screen showing white works), add it here, and convert. Black-and-white negatives come out well; colour negatives have an orange film base, so the result will look blue and needs colour correction afterwards.
What does inverting colours mean?
Each colour is replaced by its opposite: black becomes white, red becomes cyan, blue becomes yellow. Converting the result again gives you back the original.
Is the image file uploaded?
No. The image is read and converted by your browser on your own device. Nothing is sent to a server, and nothing is stored.
Can I convert several image files at once?
Yes. Add as many as you like; each becomes a negative, and they download together as a ZIP.
Is there a size or daily limit?
No limits and no watermark. Very large images (over about 50 megapixels) may be slow on older phones because the work happens on your device.
