Blur Background creates a local subject mask, blurs the original image behind it, and composites the subject back on top. This gives portraits and product shots a softer background while keeping the photo in your browser.
Adjust blur radius, edge softness, output format, and JPG quality before exporting. PNG is useful for crisp edges, while JPG can be smaller for finished photos.
Automatic edge matting can struggle with hair, glass, shadows, motion blur, or similar foreground and background colors. Review the preview before publishing or sending the result.
No. The subject mask and canvas compositing run entirely in your browser. Your image stays local.
Convertful estimates a foreground matte from the image edges, blurs the original image behind it, and composites the subject back on top.
Yes. Adjust blur radius, edge softness, output format, and JPG quality before downloading.
Automatic matting is an estimate. Fine hair, glass, motion blur, similar foreground/background colors, and busy scenes can need review.
PNG is best for preserving clean edges. JPG is available when you want a smaller flattened image.
