Manga Colorizer is an AI-powered online tool that colorizes black-and-white manga pages and translates text into 15+ languages, preserving original line art, panel layouts, and screentones while exporting at up to 4K resolution.
What is Manga Colorizer?
Manga Colorizer is a web-based AI manga colorizer and translator built specifically for manga and comics, not generic photos. It accepts black-and-white manga pages (PNG, JPG, WEBP) and outputs full-color chapters with optional translation, style presets, and a built-in reader. The platform runs on image models including Nano Banana Pro on top of Gemini, tuned for manga line art. It is available at Manga Colorizer.
Key Features
- Manga-aware AI coloring — Uses Nano Banana Pro on Gemini to fill flat areas cleanly while preserving every inked line, panel border, and screentone; outputs crisp colors without smudging detail.
- 15+ language translation — AI detects speech bubbles, narration boxes, and sound effects, replaces them with translated copy in English, Japanese, Spanish, French, German, Korean, Turkish, and more without hand-redrawing lettering.
- 2K and 4K high-resolution export — Processes full pages at up to 2K or 4K resolution, unlike many online colorizers that cap at 1200px. Colored chapters stay sharp on tablets, monitors, and print spreads.
- Style presets and palette locking — Choose from presets (soft pastel, bold action, vintage print, webtoon tone) and lock character colors at the chapter level so main cast, locations, and props stay consistent across pages.
- Batch mode and chapter-level processing — Upload multiple pages and reuse the same style settings across a chapter. The AI colorizes and translates in a single pass, maintaining consistent palettes from first to last page.
- Built-in chapter reader and private sharing — Compile colored pages into a chapter, open in the reader, and share a private link with beta readers or collaborators. Individual pages and full chapters are downloadable at any time.
Who is it for?
- Manga fans reading raw releases — Drop raw black-and-white chapters into Manga Colorizer, translate into their native language, and read the colored version in the built-in reader without file wrangling.
- Indie creators prototyping color editions — Colorize a chapter in minutes, share the reader link with beta readers, and use the output as a base pass for finishing artists instead of starting from blank flats.
- Scanlation and localization teams — Go from raw pages to readable chapters without hiring a full coloring crew. The tool handles base colors and translation drafts, letting editors and typesetters focus on polish.
What can you do with Manga Colorizer?
- Colorize full manga chapters — Upload a 22-page chapter and colorize it in about 10 minutes using style presets that keep palettes consistent across pages. Export at 2K or 4K for crisp viewing.
- Translate colored pages into multiple languages — Run the same colored edition through translation for English, Spanish, French, Turkish, and more without re-running the coloring step. Speech bubbles, narration, and SFX are all handled.
- Create a shareable reader for collaborators — Compile pages into a chapter and generate a private link. Beta readers, translation groups, or licensing partners can view the full chapter online without downloading files.
- Export high-resolution assets for social media or print — Download 2K or 4K files that stay sharp after Instagram compression or on 27-inch monitors, suitable for fan posts, motion videos, or prototype spreads.
