What is Kolorize?
Kolorize is an online AI photo colorizer that transforms grayscale, black‑and‑white, or sepia images into color versions within 3 to 8 seconds.
Users upload JPEG, PNG, WebP, GIF, or AVIF files up to 4096×4096 pixels; larger images are automatically resampled.
The process is fully automated, preserving detail without quality loss, and outputs colorized JPG files.
All uploads travel over a 2048‑bit encrypted channel and are deleted after processing, ensuring data privacy.
Results can be downloaded for free during trial or purchased using a credit system valid for two years, and can be used for commercial projects.
