Colorize Black and White Photos
Turn black-and-white and grayscale photos into realistic color in your browser. snapnedit's AI photo colorizer reads the content of each scene and infers natural tones for skin, sky, foliage, and fabric — perfect for restoring old family portraits, wartime snapshots, and archival prints. It's completely free, needs no sign-up, and adds no watermark.

Bring old family photos back to life
Most people have a drawer of monochrome and sepia prints that feel flat and distant — a grandparent's wedding, a childhood summer, a grainy wartime portrait. Colorization closes that gap. By restoring plausible skin tones, blue sky, green grass, and the color of a favorite dress, an image that once felt like a document starts to feel like a memory again. snapnedit's colorizer is built for exactly this genealogy and heritage work: upload a scanned print, let the AI read the scene, and get a natural, share-ready result you can print, archive, or post. Because the original file is never overwritten, colorizing is completely reversible — you always keep the black-and-white master.
How AI colorization works
The model was trained on millions of color photographs, so it has learned the statistical link between what an object looks like in grayscale and what color it most likely is — grass reads green, denim reads blue, a face reads as skin. When you upload a black-and-white image, it predicts a color value for every pixel while keeping the original brightness and detail untouched, then hands you a full-resolution PNG. There are no sliders or masks to set up: colorize takes no parameters, so one click does the analysis for the whole frame. Inputs up to 4096 pixels on the long edge are supported, which comfortably covers most scanned prints and negatives.
Get the cleanest result: prep, then colorize
Colorization tints whatever it sees, so damage matters. Creases, dust specks, and tape marks read as texture and can pick up odd colors, so clear them with the Magic Eraser or Retouch tool first. If your scan is soft, speckled, or shot at high ISO, run AI Denoise before colorizing so the model isn't guessing color from noise. For small or low-resolution scans, Upscale first to give the colorizer more detail to work with. Once you have color, you can keep going in the editor — nudge the white balance, warm the skin tones, or boost saturation — to fine-tune the AI's interpretation to taste.
Free for real restoration projects
snapnedit runs on self-hosted AI, and every in-browser tool is free to use — there's no trial limit, no daily cap of two photos, and no account gate before you can download. Results come out clean with no watermark stamped across them, exported as PNG so fine detail and edges stay crisp. That makes the colorizer genuinely usable for real projects: reunion slideshows, memorial boards, ancestry albums, or a framed print for a relative, without paying per image or signing up for a subscription just to save your work.
How it works
Upload a black-and-white or grayscale photo — ideally a repaired, denoised scan for the cleanest result.
Our self-hosted AI reads the scene and generates realistic, natural-looking color automatically, with no settings to adjust.
Download the colorized photo as a watermark-free PNG, or open it in the editor to fine-tune the tones.
Frequently asked questions
How accurate are the colors?
The AI infers plausible, realistic colors from the scene, but it can't know the true original color of something it never saw — a specific dress or car could have been any hue. Treat the result as a faithful artistic restoration rather than a factual record of the exact colors.
Is it really free with no watermark?
Yes. Every in-browser tool on snapnedit is free, with no sign-up and no watermark on your download. Credits only apply to the API; using the site and exporting your colorized photo costs nothing.
Does it work on old scanned prints?
Yes — that's the main use case. Colorization works well on scanned prints, including faded or low-contrast originals. Very degraded scans give better results if you repair and denoise them first.
What file formats and sizes are supported?
Upload common image formats and download a PNG. Inputs up to 4096 pixels on the longest edge are accepted, which covers most scanned photos and negatives; larger files are scaled to fit before processing.
Should I repair a damaged photo before colorizing?
Yes. Creases, dust, and tears read as texture and can pick up strange tints, so clean them with the Magic Eraser or Retouch first, and denoise a speckled scan — then colorize the repaired version for a cleaner result.
Can I adjust the colors after the AI generates them?
Absolutely. Open the colorized result in the snapnedit editor to tweak white balance, warmth, and saturation, or paint local corrections on top of the AI's colors until the image looks the way you want.
Will it change the faces or details in my photo?
No. Colorization only adds color; it keeps the original brightness, contrast, and detail intact, so faces and textures stay exactly as they were in the black-and-white original.
Can I colorize a color photo to fix faded tones?
The tool is designed for black-and-white and grayscale images. For a color photo that has faded or shifted, use the editor's white balance and color adjustments rather than the colorizer.
