Colorize Image · Turn Black and White Photos into Color with AI

Upload the photo, choose a color style (Natural suits most family photos), add color hints if you know any, pick 2K or 4K and click Colorize Image. Drag the slider to compare, then download. To colorize old photos by hand instead, follow the Photoshop and GIMP steps above.

The colorization AI has learned from a very large number of color photos which colors usually belong to which shapes and textures: skin, hair, denim, leaves, sky, brick. It reads the gray tones of your picture, recognizes those parts and paints each with a plausible color, keeping the light and shadow of the original.

Not guaranteed. A black and white photo stores brightness, not color, so the AI chooses colors that are plausible for the scene and the era. Skin, sky and foliage usually look right; uniforms, flags, cars, signs and painted walls may not match what was really there. For historical work, check your sources, add color hints and label the result as colorized.

No. A red dress and a green dress can turn into the same gray, so the colorizer has to make a guess. If you know the real colors, type them as color hints and run it again. If one item still comes out wrong, the image color changer can recolor just that object.

The tool is told to keep every face, expression, pose and detail as it is and only add color. Because it runs on an AI restoration model, very fine texture such as film grain, hair strands or fabric weave may be slightly redrawn, and small damage may be cleaned up. Compare the slider at full size and keep the original scan as your archive copy.

Yes. Choose Sketch & drawing to colorize sketch pages, line art, ink drawings, comic panels and AI sketches. It fills shapes with clean flat colors and soft shading and keeps the original lines; hints such as “blue sky, red jacket” steer the palette. If you colorize PNG line art with a transparent background, expect the result on a solid background.

That is what this tool does. It runs on Nano Banana 2, an AI image model that is good at restoring and editing photos, with instructions written for colorizing: keep the people and the composition, add natural color, follow your hints. You do not need to write a prompt; just pick a style.

JPG, PNG and WebP files up to 10 MB, whether grayscale, sepia or faded color. For a PDF or a TIFF from a scanner, export the page as JPG or PNG first. Only upload photos you own or have permission to edit: your own pictures, family archives and public-domain images are fine.

Yes, with a different tool. The black and white photo converter is a free colour to black and white converter that runs in your browser, with film-style lens filters and contrast sliders. It works as a color to black and white photo editor for portraits, and painters use it as a quick color to black and white paint value check.

It is free to try. New accounts get free credits when they sign up, so you can colorize old photos free with those credits and judge the colors yourself. After that, each photo uses credits from your balance, and 4K output uses more than 2K.
