100% private — files never leave your deviceYour browser can’t run this tool. Please try the latest Chrome, Edge or Safari on a desktop.
Loading the AI model (first time only)…
The AI model (~120 MB) downloads once, then runs entirely on your device — this can take a few seconds on the first run. It’s cached afterwards, so next time is instant.
How to use
- Open your photo. Drag a black-and-white or grayscale image onto the page, or click to browse and select it.
- Let the AI work. The in-browser model adds color automatically; the first run downloads the model once before processing.
- Compare the result. Preview the colorized version next to the original to see how the AI interpreted the scene.
- Download your photo. Save the colorized image to your device with one click, ready to share or print.
Features
- Fully private by design. Your photo is processed locally in your browser and is never uploaded to any server.
- Automatic AI coloring. No brushes or manual masking needed; the model estimates colors for skin, sky, foliage, and objects on its own.
- Works offline after first use. The AI model is cached after the initial download, so repeat colorizations run without an internet connection.
- Free with no sign-up. There are no accounts, watermarks, or per-image limits, just open the page and colorize.
When to use it
- Restore color to inherited family photos and old portraits before sharing them with relatives.
- Add a modern feel to scanned vintage prints for scrapbooks or memory books.
- Preview how a historical or archival black-and-white image might have looked in color.
- Refresh grayscale snapshots for social media posts without sending them to a cloud service.
- Experiment with coloring artwork or sketches to explore palette ideas.

Frequently asked questions
Is this photo colorizer free?
Yes, it's completely free with no sign-up, no watermarks, and no limit on how many photos you colorize.
Are my photos uploaded anywhere?
No. Everything runs locally in your browser using an AI model on your device, so your images never leave your computer or phone.
What image formats and sizes are supported?
Common formats like JPG, PNG, and WebP work well. Very large images can be slow or may fail on low-memory phones, so try a smaller copy if you hit problems.
Are the colors historically accurate?
No. The colors are an AI estimate of what the scene likely looked like, not the true original colors. Results vary, and unusual clothing or objects may be colored differently than reality.
Do I need an internet connection?
Only for the first use, when a small AI model downloads and is cached. After that, the tool works offline.
Why is the first colorization slower?
The first run downloads the AI model once before processing. Later photos are faster because the model is already cached in your browser.
