Colorize Photo review
A private, free browser tool with batch processing and detailed color adjustments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Colorize Photo is a free browser-based tool for adding color to black-and-white and grayscale images. It suits people restoring personal photos, preparing visual projects, or exploring colorization without signing up or uploading images. Its neural network runs locally through WebAssembly, while the interface supports automatic colorization, intensity adjustments, eight tonal palettes, and a manual color brush for targeted edits.
The strongest fit is privacy-conscious, high-resolution browser work. Because processing happens on the user's device, photos are not uploaded. Colorize Photo accepts JPG, PNG, WebP, and other browser-supported image formats, then exports to JPEG, WebP, or PNG. Adjustable output quality and dimensions support files up to 4096 pixels, while clipboard paste and copy support can make moving images into and out of the tool more convenient.
Its editing workflow is broader than one-click colorization but remains focused on this single task. Batch processing allows multiple photos to be handled and downloaded together, and each photo has a 15-step undo history for reversing changes. The eight palettes and manual brush provide control, although users seeking highly specialized color grading or a native desktop workflow should look elsewhere. Choose Colorize Photo for free, local, browser-based colorization with practical refinement tools; avoid it if web-only access or neural-network output is not suitable for your process.
