Why do my cutout edges look jagged after background removal?

Jagged edges typically occur when the source image is low resolution or heavily compressed. The AI has fewer pixels to work with at the boundary, leading to staircase-like artifacts. Uploading a higher resolution image or using Magic Click refinement can fix this.

What is the white halo effect around my subject?

The white halo happens when remnants of a light background remain along the subject edges. The AI includes a thin strip of background pixels. Use Magic Click in erase mode to click on the halo areas and remove them.

Can I smooth edges after background removal?

Yes. Use the Magic Click refinement tool to adjust edges after the initial removal. Switch between keep and erase modes to precisely control which pixels are included in the final cutout.

Does image format affect edge quality?

Yes. JPEG compression introduces artifacts especially along high-contrast edges. PNG and TIFF formats preserve edge detail better. If your source is JPEG, try to use the least compressed version available.

How do I fix rough edges on curved objects?

Curved surfaces like bottles or rounded products benefit from multiple Magic Click points placed along the curve. Use keep mode inside the curve and erase mode outside to define a smooth boundary.

Will higher resolution images always produce smoother edges?

Higher resolution significantly improves edge quality because the AI has more pixel data at boundaries. However, extremely large images may process slower. A resolution of 2000-4000 pixels on the longest side typically offers the best balance.

The Problem

After removing the background, edges around the subject appear jagged, pixelated, or have visible halos. This is especially noticeable on curved surfaces, hair, and fine details where the AI struggles to determine the exact boundary between subject and background.

Common Causes

1.Low resolution source image causing the AI to approximate edge boundaries

2.High contrast between subject and background creating visible halo artifacts

3.JPEG compression artifacts along edges reducing detection accuracy

Step-by-Step Solutions

Use Magic Click refinement to smooth edges

Open the Magic Click tool and switch to erase mode. Click along the rough edge areas to remove halo artifacts and jagged pixels. The tool uses MobileSAM segmentation for precise edge correction.

Zoom in and use erase mode on problem areas

Zoom into the affected edge regions for precision work. Place multiple click points along the rough edges, focusing on areas where the background bleeds into the subject outline.

Try uploading a higher resolution source image

Higher resolution images give the AI more pixel data to work with at edges. If possible, upload the original uncompressed photo rather than a resized or compressed version.

Adjust click points near edge areas

Place keep-mode click points just inside the subject boundary and erase-mode click points just outside. This helps the AI learn the precise edge location in difficult areas.

Prevention Tips

Always upload the highest resolution version of your image available

Use PNG or TIFF formats instead of heavily compressed JPEGs

Photograph subjects against contrasting backgrounds when possible for cleaner initial detection
