How to Prepare Photos for the Best AI Line Art Results

Great line drawings start with the right input photo. Whether you are converting a family portrait or a product shot, a few simple adjustments can dramatically improve edge detection and the final coloring-page experience.

1. Capture balanced lighting

Use bright, even lighting to avoid heavy shadows. Natural daylight near a window works best. If you must shoot indoors, diffused lamp light from both sides keeps facial features and object edges visible for the AI.

2. Increase contrast before uploading

The generator performs best when the subject stands out from the background. Quickly bump contrast and clarity in your favorite photo editor, or use the built-in adjustments on your phone. Crisp differences between light and dark regions translate to cleaner strokes.

3. Choose the right resolution and crop

Aim for at least 1024 pixels on the shortest side. Crop out distractions that don’t belong in the final line art. Highlight the hero subject so the algorithm allocates detail to the areas you care about most.

4. Prefer PNG or high-quality JPEG files

PhotoToLineArt accepts the most common formats, but PNG preserves subtle gradients with fewer compression artifacts. If you use JPEG, export at the highest quality setting to limit noise.

5. Add context notes in the prompt (optional)

Uploading an image is usually enough. Still, you can add a short description such as “focus on facial expressions” or “emphasize floral details.” The backend blends the prompt with automated guidance to respect those preferences.

6. Review the preview gallery for inspiration

The AI Line Drawing Generator displays generated results in your sidebar history. Compare multiple aspect ratios (2:3, 3:2, 1:1) to see what fits best on your printable page, then download the winner in one click.

Applying these quick steps keeps your creative process smooth and ensures every PhotoToLineArt generation looks intentional and print-ready.
