Manga Colorizer

Manga Colorizer is a web tool that turns black-and-white manga pages into color using manga-tuned AI, with optional translation into 15+ languages, 2K or 4K export and a shareable chapter reader.

Manga Colorizer is a web-based tool that converts black-and-white manga pages into full-color pages, with optional translation of the lettering. It is aimed at manga and comics rather than photographs, so the models behind it are tuned to line art, panel layouts and screentones. According to the site, the underlying image models are Nano Banana Pro running on Gemini, and the goal is to fill flat areas cleanly while leaving inked lines and panel borders intact. The workflow is short. A user uploads one page or a batch in PNG, JPG or WEBP, optionally adds colored reference images to steer the look, and picks a style preset such as soft pastel, bold action, vintage print or webtoon tone. Translation can be switched on by choosing one of more than 15 target languages, and the tool detects speech bubbles, narration boxes and sound effects, then replaces the text while the artwork stays untouched. Coloring and translation run in a single pass. Results can be downloaded at up to 2K or 4K resolution, or compiled into a chapter that opens in a built-in reader and can be shared through a private link. Consistency across a chapter is a stated focus. Presets are repeatable, and chapter-level settings are meant to lock character palettes so the main cast does not change color from page to page. The audience falls into three groups: readers who want colorized raw chapters, indie creators who want to test a color edition before paying for hand painting, and small scanlation or localization teams that need a base pass before editors and finishing artists take over. The site itself positions the output as suited to rapid exploration, fan reading and indie projects, with polished professional work still needing human finishing. Among alternatives, it competes with general-purpose AI colorizers that handle portraits better than screentones, and with standalone manga translators that cover only translation. Its distinguishing choice is bundling coloring, translation, high-resolution export and reading in one pipeline. Pricing details sit on a separate pricing page.
