AI Photo Colorizer

Turn black & white and sepia photos into colour. The realistic mode runs the DDColor neural network entirely in your browser — it studies the scene and picks plausible, natural colours for skin, sky, foliage, and fabric. Prefer a look instead of realism? Four instant palette styles (vintage, sepia, saturated, pastel) apply with no download at all. Compare every result against the original with the built-in slider. Your photos never leave your device.

How it works

  • Drop a black & white, sepia, or faded photo (JPEG, PNG, or WebP)
  • Realistic mode runs the DDColor model in your browser — a one-time ~460 MB download you approve first, cached for offline reuse
  • Style modes (vintage, sepia, saturated, pastel) colour-grade instantly with zero download
  • Drag the slider to compare, then download the colorized PNG

Frequently asked questions

How accurate are the AI colours?

DDColor predicts plausible colours from what it learned across millions of photos — grass becomes green, skies blue, skin tones natural. It cannot know the true historical colour of a specific dress or car, so treat the result as a faithful-looking interpretation, not a record.

Why is there a 460 MB download for realistic mode?

The DDColor network weights run entirely on your device — that is what keeps your photos private. The download happens once, is cached by your browser, and works offline afterwards. If you skip it, an instant classical pass colorizes with a lighter touch instead.

Does it work on damaged or very old photos?

Yes — colorization works on any grayscale input. For heavily damaged photos, results improve if you first run the image through the upscaler or clean it up in the editor, then colorize the restored version.

Can I colorize a photo that already has some colour?

Yes. Faded or colour-cast photos are re-interpreted by the model; stylised modes apply their palette over whatever colour exists. For fully coloured photos the realistic mode makes only subtle changes.
