What is Kolorize?
Kolorize is an AI-powered online tool that transforms black-and-white photos and videos into vibrant, full-color images. Using next-generation artificial intelligence, the platform analyzes monochrome media and automatically adds realistic colors to objects, backgrounds, and facial features. The service operates through a simple three-step process: upload your photos or videos, start the AI magic, and preview/download the colorized results.
Key features include unlimited preview trials (you only pay when satisfied to download), pristine colorization that retains original photo details with zero quality compromise, support for multiple image formats (JPEG, PNG, WebP, GIF, AVIF) and video formats (MP4, AVI, WEBM, MOV), and batch upload capability for up to 20 photos. The platform also offers 2048-bit encrypted file transfer for data security, with files automatically deleted after processing.
Kolorize is ideal for history enthusiasts looking to revive old family photos, photographers wanting to add new creative dimensions to their work, archivists preserving cultural heritage, filmmakers restoring classic films, and anyone wanting to bring grandmother's old photo albums or historic footage back to life in true color. The tool processes photos in 3-8 seconds depending on size and detail, while videos typically process within an hour for a 5-minute file.
The platform supports both photo and video colorization, with 1 credit equaling 1 image download or 100 video frames. All colorized results can be used commercially anywhere, and users can download the same processed image multiple times at the same resolution without additional credit consumption.

Frequently asked questions about Kolorize
What image and video formats does Kolorize support?
Kolorize supports JPEG, PNG, WebP, GIF, and AVIF for images, and MP4, AVI, WEBM, and MOV for videos. However, image resolution will be downsampled to 4096x4096 if larger, and downloaded files after processing will always be in JPG format.
How does the AI colorization work?
Kolorize uses advanced proprietary AI technology that analyzes each frame or photo, identifying elements like objects, backgrounds, and facial features. The AI colorizes objects using colors with higher probability of being original shades (e.g., a banana is yellow or green, not blue). While not 100% reproduction of original colors, it results in reasonable approximation.
How long does colorization take?
Kolorize usually needs 3 to 8 seconds to colorize a photo, depending on size and detail. For videos, most 5-minute videos are processed within an hour, though time varies based on video length and complexity.
What is a credit and how does it work?
Credits are used to download processed images, with each download costing one credit. One credit equals 1 image or 100 video frames. Downloading the same processed image at the same resolution multiple times doesn't consume additional credits. Credits are valid for two years.
Can I use colorized photos for commercial purposes?
Yes, absolutely. All colorized results can be used anywhere, including commercial applications. There is no extra cost applied for downloading results for commercial use.
Does Kolorize work on photos that were already colored?
Certainly. The algorithms operate on every photograph to determine whether the initial photo was captured in black and white or color. Subsequently, they proceed to colorize black-and-white photos or restore colors on already colored photos accordingly.
Is human intervention required for colorization?
No, the entire process is automated and relies on specialized AI technology to accomplish the task without any human intervention. You simply upload your photo or video and the technology does the rest.
How is my data secured on Kolorize?
Files are transferred via a 2048-bit encrypted connection for photos, and Kolorize uses industry-standard encryption for videos to ensure your files and personal information are safe. Files are automatically deleted after the operation is completed.
Can I download colorized videos without extra cost?
Yes, absolutely. No extra cost will be applied for downloading video colorization results. You only pay for the credits used to process the video frames.
What copyright rules apply to colorizing videos?
You should only colorize videos for which you have the rights or permission. Kolorize recommends checking copyright status beforehand before uploading and colorizing any video content.
