AI Manga Image Colorizer

Turn black-and-white manga and anime panels into full colour.

Drop in one or more B&W panel image URLs and get back vibrant, scene-appropriate colour versions that keep the original composition and framing. No API key, no setup — you pay per panel.

---

What It Does

• Accepts a list of direct image URLs (JPG, PNG, or WebP)
• Colorizes each panel with scene-appropriate, manga-style colour and cel shading
• Returns a hosted image URL, processing time, and status per panel
• Handles failures gracefully — each image produces a record regardless of outcome

What to expect

This produces a colour re-illustration of your panel, not a pixel-perfect overlay on the original ink. The composition, framing and pose carry over, but fine details can shift between the source and the result. If you need the original linework untouched, this is not the right tool.

Inputs

Field	Type	Required	Description
imageUrls	array of strings	Yes	Direct URLs to B&W manga/anime panel images
colorStyle	string	No	Colorization style prompt. Default: vibrant manga-style colors appropriate to the scene and characters
outputSize	string	No	Output size: auto (default, keeps the source aspect ratio), 1024x1024, 1024x1536, 1536x1024
maxItems	integer	No	Maximum number of panels to colorize. Defaults to all provided

Output

Each processed image produces one dataset record:

Field	Type	Description
sourceUrl	string	Original input image URL
colorizedUrl	string	URL to the colorized image in Apify Key-Value Store
style	string	Colorization prompt used
outputSize	string	Output dimensions
processingMs	number	Round-trip time in milliseconds
model	string	Model used
colorizedAt	string	ISO 8601 timestamp
status	string	ok or error
errorMsg	string	Error details when status is error

Requirements

• Publicly reachable image URLs
• Supported formats: JPG, JPEG, PNG, WebP, GIF
• Maximum image size: 20 MB per file

No API key to obtain, and no separate vendor bill.

Pricing

$0.10 per run start + $0.20 per colorized panel.

Panels that fail (network error, unsupported format) still produce a record and are billed as one panel. There is nothing else to pay — colorization costs are included.

Free plan limit: runs on Apify's free plan are capped at 10 panels per run. Any paid Apify plan lifts the cap.

Example

Input:

{
  "imageUrls": [
    "https://example.com/manga-panel-1.jpg"
  ],
  "colorStyle": "vibrant manga-style colors appropriate to the scene and characters",
  "outputSize": "auto"
}

Output record (success):

{
  "sourceUrl": "https://example.com/manga-panel-1.jpg",
  "colorizedUrl": "https://api.apify.com/v2/key-value-stores/abc123/records/panel_xxx",
  "style": "vibrant manga-style colors appropriate to the scene and characters",
  "outputSize": "auto",
  "processingMs": 68400,
  "model": "gpt-image-2",
  "colorizedAt": "2026-08-03T12:00:00.000Z",
  "status": "ok",
  "errorMsg": null
}

Notes

• Colorized images are stored in Apify Key-Value Store (colorized-panels) accessible via the returned URLs during the run's data retention window.
• Expect roughly a minute per panel. Up to 2 panels are processed concurrently.
• Images that fail still produce a dataset record with status: "error" — the run does not abort on partial failures.
