Webtoon Comics

ImageChunker is perfect for webtoon and vertical scroll comic artists who need to split long comic pages for platform requirements.

Platform Requirements

Different platforms have different size limits:

Platform	Max Height	Max Width	Format
Webtoon	1280×20000px total, max 800px/image	800px	JPG/PNG
Tapas	940×10000px total	940px	JPG/PNG
Lezhin	690×variable	690px	JPG
Tappytoon	720×variable	720px	JPG/PNG
Self-publish	Varies	Varies	Any

Why Use ImageChunker?

Traditional comic software exports full pages. But webtoon platforms:

• Limit file dimensions — Most cap at 800-1000px height per image
• Require multiple files — Long scrolls need to be split
• Need consistent widths — All images must match
• Prefer optimized files — Balance quality vs. size

ImageChunker solves these automatically.

Workflow for Webtoon Artists

1. Export from Drawing Software

From Clip Studio Paint, Procreate, or Photoshop:

• Export as single tall PNG or JPEG
• Use your target platform’s width (e.g., 800px for Webtoon)
• Keep maximum quality at this stage

2. Import to ImageChunker

1. Open ImageChunker
2. Drop your exported page onto the window
3. The source panel shows your full comic

3. Configure for Your Platform

For Webtoon (800px wide):

Setting	Value
Mode	Smart (detects panel boundaries)
Chunk height	800px (safe limit)
Format	JPEG
Quality	85-90%

For Tapas (940px wide):

Setting	Value
Mode	Smart
Chunk height	940px
Format	PNG

4. Smart Chunking for Comics

Smart mode is ideal for comics because it:

• Detects panel gutters — Splits between panels, not through them
• Recognizes speech bubbles — Keeps dialogue together
• Finds natural breaks — Empty space between scenes

If Smart mode doesn’t find good splits:

• Increase sensitivity
• Or use Regular mode with manual height

5. Preview and Adjust

Review each chunk:

• ✓ No panels cut in half
• ✓ Speech bubbles complete
• ✓ Action sequences intact
• ✓ Text fully visible

6. Export

Export with appropriate naming:

episode_01_001.jpg
episode_01_002.jpg
episode_01_003.jpg

Or with page context:

ep01_page01_001.jpg
ep01_page01_002.jpg

Panel-Aware Splitting

How It Works

Smart Chunking in comic mode:

1. Scans for gutters — White/empty horizontal bands
2. Detects panel borders — High contrast horizontal lines
3. Identifies safe zones — Areas with minimal content
4. Prioritizes splits — Prefers larger gutters over small ones

Best Practices for Artists

To get optimal splits:

1. Consistent gutter width — Use 10-30px gutters between panels
2. Clear panel borders — Solid lines help detection
3. Avoid full-bleed panels — When possible, leave margins
4. Consider split points — When drawing, think about where cuts might occur

Handling Full-Bleed Panels

If you have panels without gutters:

1. Use Regular mode with fixed height
2. Or add minimal overlap (5-10px)
3. Check preview for any awkward cuts

Batch Processing for Episodes

When you have multiple pages per episode:

Sequential Workflow

1. Export all pages from drawing software
2. Add all pages to ImageChunker batch queue
3. Use consistent settings for entire episode
4. Export with episode-aware naming

Naming Convention

Settings:
Prefix: s01e01_
Pattern: {prefix}page{num2}_chunk{num2}

Output:
s01e01_page01_chunk01.jpg
s01e01_page01_chunk02.jpg
s01e01_page02_chunk01.jpg

Tips for Comic Artists

Preserve Quality

• Export source at 2x resolution, then let ImageChunker resize
• Use PNG for line art with solid colors
• Use JPEG for full-color painted comics

Optimize for Mobile

Most webtoon readers are on phones:

• Keep text readable at small sizes
• Avoid tiny details in gutters
• Test on your own phone before publishing

Consistent Style

For series:

• Save ImageChunker presets per series
• Use same settings across episodes
• Document your workflow for consistency

Backup Original Files

Always keep:

• Original layered files (PSD, CLIP, etc.)
• Full-resolution exports
• ImageChunker project settings
