Upload Guide

The quality of your character image is crucial to getting exceptional results on CoinLab. This guide shows exactly which types of images work best and how to avoid common problems.

Accepted Image Types

• Formats: PNG, JPG, JPEG, WEBP, AVIF, GIF

• Content: Exactly 1 character visible

• Resolution: Maximum 2048px, recommended 1024-1024px

• Size: Maximum 20MB per image

• Quality: Sharp and well-lit image

Visual Examples - Recommended Images

✅ Example 1: Full Character, Neutral Background

Why it works:

• Whole body visible or cropped (images with a cropped character give the AI freedom to generate missing body parts that may be distinct and inconsistent)

• Simple background

• Even lighting

• Centered character

✅ Example 2: Half Body, Natural Pose

Why it works:

• Clear and natural pose

• Well-defined clothing

• Visible facial expression

• No distracting elements

• AI generates missing body parts that are anatomically and stylistically consistent with the character's features

✅ Example 3: Character with Distinctive Features

Why it works:

• Clear unique features

• Proper contrast

• Visible details

• Focus on the character

Visual Examples - Not Recommended Images

❌Example 1: Multiple Characters

example:

❌ INCORRECT

✅ CORRECT

Why it doesn't work:

• Confuses the AI about which character to use (even when adding the trait)

• Inconsistent results

• Loss of visual focus

❌ Example 2: Cropped Parts

❌ INCORRECT

✅ CORRECT

Why it doesn't work:

• Cut-off head or limbs cause the AI to create its own version of the character's missing parts

• Different and inconsistent results

• Possibility the AI will generate the image with missing body parts or with inconsistent features.

❌ Example 3: Busy Background

❌ INCORRECT

✅ CORRECT

Why it doesn't work:

• Distracting elements

• Confuses the AI's analysis

• High chance the result quality will be compromised

❌ Example 4: Low Quality/Blurry

❌ INCORRECT

✅ CORRECT

Why it doesn't work:

• Details not visible

• AI cannot analyze features

• Low quality results

Technical Specifications

Recommended Formats

Format	Advantages	Recommendation
PNG	Lossless, transparency	⭐ Best for quality
JPG	Smaller size	⭐ Good for generations
WEBP	Compact and quality	⭐ Ideal balance

Ideal Resolution

• Recommended: 1024x1024px to 2048x2048px

• Maximum: 2048x2048px

• Aspect Ratio: Square or rectangular (not too elongated)

File Size

• Recommended: 500KB - 7MB

• Maximum: 20MB

Best Practices

✅ Correct - Do

• One character per image

• Simple background

• Even lighting

• Natural pose (standing, frontal)

• Visible clothing and traits

• High resolution and sharpness

• Proper contrast

❌ Incorrect - Avoid

• Multiple characters

• Busy or complex background

• Cropped parts (head, arms, legs)

• Extreme angles (back view, very close-up)

• Low quality or blurry

• Distracting elements in the image

• Too dark or overexposed

Common Issues

Problem: "Result doesn't look like the character"

Cause: Multiple characters or complex background Solution: Use only 1 character with a simple background (try another image of the character)

Problem: "Low quality in generation"

Cause: Original image of low quality Solution: Use a sharp, well-lit image with good resolution

Problem: "Missing parts in the result or inconsistent results"

Cause: Character cropped in the original image Solution: Include the full character in the image

Problem: "Style not applied correctly"

Cause: Trait too complex or vague Solution: Use simple and specific traits
