Turn black and white photo into color online free

How to use

1. 1

   Open your black and white photo

   Drag and drop a photo onto the page, paste it with Ctrl+V (⌘V on Mac), or click “Choose photos”. Any browser-supported format works — JPG, PNG, WebP, TIFF. No file-size limit because nothing leaves your device.

2. 2

   AI turns it into color automatically

   A neural network running locally on your device analyzes the image and predicts natural colors — skin tones, skies, foliage, clothing, wood. The model downloads once (about 39 MB) and is cached for instant reuse.

3. 3

   Adjust colors to your liking

   Pick from 8 tonal palettes (warm, cool, vivid, sepia and more) to shift the overall mood, or switch to the Paint brush to set exact colors on specific areas. 15 undo steps let you experiment freely.

4. 4

   Download your color photo

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

Tips for the best color conversion

• Start with the sharpest source you have

  The AI reads texture and tonal gradients to predict colors. A high-resolution scan (300 DPI+) or an original digital file gives the model more context and produces more accurate results.

• Try tonal palettes before manual painting

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

• Dial back intensity for a period-accurate look

  Full intensity creates modern, saturated tones. Reducing it to 50–70% produces subtler colors that suit early-to-mid 20th century photographs without looking artificially vivid.

• No file-size limit — everything stays on your device

  Because the tool runs in your browser, there is no upload cap and no server queue. Large scans, high-megapixel originals, and converted TIFFs all process locally.

FAQ

Can I really turn a black and white photo into color online for free?

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

Do my photos get 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.

How does AI turn a grayscale image into color?

The model was trained on millions of color photographs. It learned associations between grayscale patterns and likely colors — for example, sky areas tend to be blue, foliage green, and skin warm. It applies those predictions to your image in seconds.

Does it work on my phone?

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

What if the AI picks the wrong color?

Use the manual paint brush to override any area. Pick the correct hue, brush over the region, and the tool blends it naturally. You also have 15 undo steps to experiment risk-free.

Can I convert multiple photos at once?

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

Is there a resolution or file-size limit?

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

What output formats are available?

JPEG, WebP, or PNG — with an adjustable quality slider and custom dimensions. A live file-size estimate shows the final size before you download.
