MergeImages Photo Colorizer

What MergeImages Photo Colorizer is

MergeImages Photo Colorizer is a free browser tool that predicts colors for black-and-white photos, scans, and archive prints. It is suited to old family photographs, scanned prints and negatives, genealogy collections, archives, and historical images. Open its page, provide an image, and download the colorized result; no account, email, browser extension, or app is needed. The tool accepts JPEG, PNG, WebP, and GIF files up to 7.5MB. You can also paste an image or provide an image URL. Processing uses DDColor on Replicate, applying predicted color at 80% strength while retaining the source image’s brightness channel. Results download as PNG files, with the longest side capped at 1024 pixels. The site says a typical colorization takes about 20 seconds, though a cold start can take up to a minute. Images travel over HTTPS to MergeImages’ servers and Replicate, and are automatically deleted within 7 days. The maker says images are not sold, shared, or used to train models. Color choices are estimates: sepia input may be interpreted differently, and the tool does not repair scratches, tears, or fading. MergeImages is built and maintained by Bello M. Amadou.

Who it suits

This tool suits people who want to add predicted color to old family photos, scanned prints, negatives, genealogy materials, archives, or historical images. It is also a fit for someone who wants a browser-based process without creating an account or installing an app.

Limits

The free plan accepts uploads up to 7.5MB and caps the output’s longest side at 1024 pixels. An automatic per-IP cap is used to stop bots; the plan has no credits, watermark, or daily counter.

Getting started

1. Open the Photo Colorizer page in a browser.
2. Upload a JPEG, PNG, WebP, or GIF up to 7.5MB, paste an image, or enter an image URL.
3. Wait for the colorization to finish; typical processing takes about 20 seconds, with cold starts sometimes taking up to a minute.
4. Download the result as a PNG.

Verdict

Pick MergeImages Photo Colorizer for a simple browser workflow to add estimated color to older photos and scans, with no account required. Look elsewhere if you need image repairs or output beyond the 1024-pixel longest-side cap.
