❓ Frequently Asked Questions – Background Remover
What types of backgrounds work best with this tool?
This tool uses flood-fill color detection, which works best with solid-color or near-solid-color backgrounds — white backgrounds, blue sky, green screen, studio backgrounds, plain paper. Complex or detailed backgrounds (like outdoor scenes with grass and trees) are more challenging because the background colors blend with the subject. For best results, use images with clear contrast between the subject and background.
How does the Tolerance setting work?
Tolerance controls how similar a color must be to the clicked color to be removed. At Tolerance 10, only pixels very close in color to the clicked point are removed. At Tolerance 60, a wider range of similar colors is included — useful for backgrounds with slight color variation (like gradients or slightly uneven lighting). Start at 30 and adjust up or down based on results.
Can I remove multiple background areas?
Yes. Click multiple times on different background areas to remove them all. Each click is additive — it removes the clicked area while keeping previous removals. Use Undo to revert the last click if needed. The Restore tool lets you paint back areas that were incorrectly removed.
What is Edge Smoothing / Feathering?
Edge Smoothing (Feathering) applies a blur to the edges of the removed area, creating a gradual transparency transition rather than a hard cut. A feather value of 1-2 gives subtle softening, while 5-8 creates very soft, blended edges. This is useful when compositing the image onto a new background — soft edges look more natural.
What format should I download in?
Download as PNG to preserve transparency — this is the standard format for images with transparent backgrounds. If you choose a replacement background color (white, black, or custom), you can download as JPG for a smaller file size. Note that JPG does not support transparency, so it should only be used when you've chosen a solid replacement background.
