What "free" actually means here

Most "free" colorizers watermark the result, cap it at thumbnail size, or demand an account before you can download. This one doesn't:

No watermark. The colorized image you download is clean — no logo, no overlay, no stamp in the corner.
No sign-up required. Upload, colorize, and download without creating an account or entering an email address.
Full-resolution download. You get the actual result, not a shrunken preview with the real file behind a paywall.
No software to install. Runs in the browser on desktop, iPhone, and Android. Nothing to download or update.

Curious what happens to your photo after you upload it? Short version: it is uploaded securely, processed by the AI model, and the result is returned to you — see the privacy policy for the details. And if you want the reverse conversion, the color to black and white converter never uploads your image at all — it runs entirely in your browser.

Frequently Asked Questions

Is this photo colorizer really free?

Yes. You can upload a black and white photo, colorize it with AI, and download the full-resolution result without paying and without creating an account.

Does the free version add a watermark?

No. The downloaded image has no watermark, logo, or overlay of any kind. What you see in the before/after preview is exactly what you download.

Do I have to sign up or give my email?

No. The colorizer works without an account. Sign-in exists for people who want it, but it is not required to colorize and download photos.

Is there a limit on image size?

You can upload JPG, PNG, GIF, or WebP images up to 20MB. That comfortably covers high-resolution scans of old prints.

Why is it free — what is the catch?

There is no catch on the result: no watermark and no forced account. Running AI models costs us money, so we may add optional paid extras over time, but the core colorizer you see on this page is free to use.
