Colorize photo online free

How to use

1. 1

   Open any black and white photo

   Drop a photo onto the page, paste it with Ctrl+V (⌘V on Mac), or click “Choose photos”. JPG, PNG, WebP and any browser-supported format all work — there is no file-size limit because nothing gets uploaded.

2. 2

   AI colorizes it automatically

   A neural network running on your device predicts realistic colors — skin tones, sky, foliage, clothing. The model downloads once (about 39 MB) and is cached by your browser for instant reuse.

3. 3

   Fine-tune colors if you want

   Choose from 8 tonal palettes for a different mood, or switch to the Paint brush to set exact colors on specific areas. 15 undo steps let you experiment risk-free.

4. 4

   Download or copy the result

   Pick JPEG, PNG or WebP, set quality and dimensions with a live file-size preview, and download. Use “Copy” to paste it straight into a chat or document, or “Download all” for batch export.

• Start with a clear, high-resolution scan

  The AI reads texture and tonal detail to pick colors. A sharp source image — 300 DPI scan or an original-size digital file — gives the model more context and produces more accurate colors.

• Try different color styles before painting manually

  The 8 built-in palettes shift the overall mood in one click — warm, cool, sepia, vivid and more. Often one of them gets you close enough that you only need the brush for small corrections.

• Use the intensity slider for period-appropriate color

  Full intensity gives modern, saturated tones. Dialing it back to 50–70% creates a subtler, more era-accurate look that suits photos from the early-to-mid 20th century.

• No file-size worry — everything stays local

  Because the tool runs entirely in your browser, there is no upload cap and no server queue. Large scans, RAW-converted TIFFs, multi-megapixel originals — they all process locally on your device.

FAQ

Is this photo colorizer really free?

Yes — 100% free with no limits on the number of photos. There is no signup, no watermark, and no hidden paywall. The AI model runs locally in your browser.

Do I need to create an account?

No. There is no account, no email, no login. Open the page, add your photo, and download the colorized result. That’s it.

Are my photos uploaded to a server?

No. The neural network runs entirely inside your browser via WebAssembly. Your photos never leave your device — there is no upload, no cloud processing and no server-side storage.

Does it work on phones and tablets?

Yes. The tool runs in any modern browser — Chrome, Safari, Firefox, Edge — on desktop, phone or tablet. No app install needed.

How accurate are the AI-predicted colors?

The model handles natural subjects well — skin, sky, grass, wood, fabric. For specific colors it can’t know from context alone (like the exact color of a car), use the manual paint brush to set the hue yourself.

Can I colorize several photos at once?

Yes. Add as many images as you like, apply your preferred color style and quality settings, then use “Download all” to export every colorized photo in one click.

What output formats can I save in?

JPEG, WebP or PNG — with an adjustable quality slider and custom dimensions up to 4096 px on the longest side. A live file-size estimate shows the result before you download.

Is there a file-size or resolution limit?

No upload limit, because nothing is uploaded. The tool handles images up to 4096 px on the longest side. Processing happens on your own device, so speed depends on your hardware, not a server queue.
