How to Remove Image Backgrounds
SmarterSources' background remover lets you erase solid-colored backgrounds from images and export them as transparent PNGs. Everything runs in your browser — no uploads, no AI cloud services, complete privacy.
Auto Mode
Auto mode samples colors from the edges of your image to detect the background color, then removes all connected pixels that match within the tolerance range. This works best for images with solid or near-solid backgrounds (white, green screen, studio backdrops).
Pick Color Mode
Click directly on any color in your image to select it for removal. This gives you precise control over exactly which color gets erased. Useful when the background isn't at the edges or when you want to remove a specific color from within the image.
Tolerance Control
The tolerance slider controls how closely a pixel must match the target color to be removed. Low tolerance (0-15) removes only exact color matches. Medium tolerance (20-40) handles slight variations from lighting and compression. High tolerance (50+) removes a wider range of similar colors.
Frequently Asked Questions
What types of backgrounds can this remove?
This tool works best with solid or near-solid backgrounds — white backgrounds, colored backdrops, green screens, and studio shots. For complex backgrounds (outdoor scenes, busy patterns), results will vary. Adjust the tolerance to find the right balance.
What format is the output?
The output is always PNG, since it's the most widely supported format for transparent images. The removed background areas become fully transparent pixels.
Why are parts of my subject being removed?
This happens when parts of your subject are similar in color to the background. Lower the tolerance to make the color matching more strict. You can also try Pick Color mode to target the exact background color.
Is this the same as AI background removal?
No. AI-based removers use machine learning to identify subjects and backgrounds regardless of color. This tool uses color-based detection, which works great for solid backgrounds but won't separate complex scenes. The advantage is that it's instant, free, private, and requires no server processing.
Can I undo the removal?
Yes. Click "Undo Changes" to restore the original image and try again with different settings.
