MORE THAN A SINGLE CLICK

A little intelligence.
A lot of creative control.

Real local AI colorization

A DeOldify neural model estimates different colors across a black-and-white image. No external image service or per-image API charge.

Tones that feel right

Start with Natural, Vivid, Warm or Cool. Refine color intensity, original-color blend, warmth, tint, brightness and contrast.

Fine-tune one small area

Brush in a chosen color while preserving light and shade. Restore original pixels, undo a correction or redo it.

Original detail stays yours

The original image supplies texture, geometry and transparency. Download at original dimensions in PNG, JPG or WebP.

FROM THEN TO NOW, IN THREE STEPS

Bring color back, at your own pace.

A LITTLE CLARITY

Photo Colorizer: questions & answers

Useful answers. Clear next steps.

At a glance

To colorize a photo, choose, drop or paste one supported image. Colorization starts automatically by default; turn off Automatically colorize after upload to start manually with Colorize photo. A local DeOldify neural model estimates colors; the original provides full-resolution luminance detail, geometry and alpha. Compare side by side or with a before-and-after slider. Tune color intensity, original-color blend, warmth, tint, brightness and contrast, or paint a color correction and restore original pixels with undo/redo. Prepare an original-size image or a smaller preview in PNG, JPG or WebP. Pictures are not uploaded to an image-processing server. First-use AI and runtime files are about 75 MB and can be cached locally. Maximum file size is 350 MB; there is no fixed application pixel/megapixel limit, but browser memory and canvas limits apply. Colors are estimates, not a recovery of exact historical colors. GIF uses its first frame; supported AVIF depends on the browser. Shared trial and paid-pass access apply.

How do I add color to a black-and-white photo?

Choose, drop or paste a black-and-white photo. By default, local AI starts adding color automatically after the photo opens. Watch the Upload, Add color and Download steps, compare the result, adjust its tones and prepare a PNG, JPG or WebP download. Turn off Automatically colorize after upload if you prefer to start manually. The samples work the same way.

Does the tool use real AI or only a color filter?

It uses a local DeOldify neural model to estimate different colors across the image. The original image supplies luminance detail and transparency; only estimated color is transferred from the model. Warmth, tint and color presets are separate adjustments applied after colorization.

Will the colors exactly match the original scene?

No. A black-and-white photo does not contain enough information to recover its exact historical colors. AI creates plausible estimates and may color faces, clothing or backgrounds incorrectly. Use the color brush, Restore original and comparison views to review and correct the result.

Can I keep the original image dimensions and transparency?

Yes. Prepare full-size image uses the original decoded dimensions. PNG and WebP keep source transparency; JPG puts transparent areas on white. The smaller preview is at most 1200 pixels on its longest edge and never enlarges a small input. Model inference uses a 256-pixel working image for color estimates, while full-size output retains detail from the original.

Are my photos uploaded or stored on a server?

No photo-processing upload occurs. AI inference and adjustments run in your browser worker. Model files may be saved in browser cache. Your edits stay in the open page, so download them before closing or reloading. Feedback images are only sent if you explicitly submit the separate feedback form.

Why can the first photo take longer?

First use downloads about 75 MB of model and runtime files and starts the local AI engine. These files can be reused from browser storage. Processing time depends on your device, memory and connection. Cancel stops the worker; you can retry with your unchanged original.

What files and image sizes can I use?

Use JPG, PNG, WebP, BMP, GIF first frame or browser-supported AVIF, one image at a time, up to 350 MB. There is no fixed application pixel or megapixel ceiling. Your device still needs enough memory and browser canvas support. This tool does not repair scratches or reconstruct missing photo detail.

Can I restore a faded color photo, and what does access cost?

Yes. Use Keep original colors to blend existing colors with the AI estimate, then adjust intensity, brightness and contrast. The shared all-tools 30-minute trial and published one-time access passes apply. Registered accounts can start 30 continuous minutes every 3 hours. There is no separate per-image AI service charge.
