Invert Image Colors

Make a negative of any picture: black turns white and every colour flips to its opposite

Processed in your browser. Nothing is uploaded. Checked against sources on 15 Oct 2026.

Inverting turns every colour into its opposite: black becomes white, blue becomes orange, and a photo looks like a film negative. People use it to read a dark screenshot on paper without wasting ink, to turn a scanned black and white negative back into a print, or to make a white-on-black logo black-on-white. Transparent areas stay transparent, and nothing is uploaded.

How to invert the colours of an image

1

Add the image; it opens already inverted, black turned white and every colour to its opposite.

2

Lower Invert below 100 for a partial effect; 50 turns every pixel mid-grey.

3

Choose PNG output for a screenshot or diagram so the edges stay crisp.

4

Press Apply and download the inverted image.

How Invert Image Colors works

Image Filters changes the look of a photo with one tap: black and white, high-contrast black and white, sepia, vintage, vivid, warm, cool, faded, inverted, sharpened or softly blurred. Each preset is a starting point. Nine sliders then adjust brightness, contrast, saturation, warmth, grayscale, sepia, invert, blur and sharpen, and the preview shows the result on your photo as you move them.

How the colours are worked out. The black and white, sepia, saturation, invert, brightness and contrast formulas are the ones web browsers use for CSS filters, published by the W3C, so a sepia photo here matches a sepia effect on a web page. Black and white weighs green most and blue least (71.5, 21.3 and 7.2 percent for green, red and blue), the way the eye judges brightness, so colours of equal strength do not all turn the same grey. Warmth raises red and lowers blue by up to 12 percent.

Several photos. Add up to 20 photos of up to 50 MB each. The same filter is applied to all of them, and they download together as a zip. JPG, PNG and WebP keep their format; HEIC, BMP and other formats are saved as JPG, and GIF and AVIF as PNG. Transparent areas stay transparent.

The rest of the article, and all 6 questions about Image Filters, are on the Image Filters page.

Frequently asked questions

How do I add a filter to a photo online?

Drop the photo on the page, tap a preset such as Black and white, Sepia, Vintage or Vivid, and adjust the sliders if you like. The preview updates as you go. Press Apply, then Download. The filter runs in your browser and the photo is never uploaded.

How do I make a picture black and white?

Add the picture and tap Black and white. Each colour becomes the grey that matches how bright it looks, with green weighted most and blue least. For deeper blacks choose High-contrast B&W. The photo keeps its format, so a JPG stays a JPG.

Will a filter reduce the quality of my photo?

Colour filters change only the colours, never the size in pixels. A JPG or WebP is saved again at the quality you choose, 90 by default, which is hard to tell from the original. PNG is lossless. Strong blur and sharpen change detail by design.

Are my photos uploaded?

No. Every filter is worked out by your own browser on your own device, so the photos never reach a server. The page keeps working offline once loaded, and private pictures stay private. Camera details such as location are not copied into the saved files.
