How to use Refine Edges of an Image
- 1. Upload the cut-out image. Add a PNG or other image with a transparent background, ideally one produced by a background removal or chroma key step that left rough edges.
- 2. Set the Strength percentage. Increase Strength to smooth more of the alpha edge and remove stray fringe pixels; a lower value makes lighter, more conservative adjustments to detail-heavy edges like hair.
- 3. Download the cleaned cut-out. Save the result once the outline looks clean in the preview. The interior of the cut-out and its opaque pixels are left untouched.
When to use Refine Edges of an Image
Refine Edges of an Image smooths and cleans the transparent border of a cut-out, removing the halo of leftover background color that background-removal tools often leave behind. Reach for it right after cutting an object out and before compositing it elsewhere.
- Cleaning up a background-removal result. You ran a photo through a background removal tool and the subject now has a faint white or green fringe along the hairline. Refining the edges smooths that residue into a tidier alpha border.
- Prepping a cut-out for a composite. A product photo is being layered onto a new background in a design mockup. Cleaning up jagged or noisy edges first keeps the seam between the product and the new backdrop from looking obvious.
- Fixing a rough manual mask. A cut-out made by hand in an image editor has a slightly uneven, pixelated outline. Running it through this tool smooths the transition without needing to redo the masking work.
