Make a transparent PNG by removing one chosen color from a logo, illustration, product photo, or screenshot (a simple chroma key). When you load an image, the background color is auto-detected from the corners, so a flat white background or a green screen often drops out right away. If it doesn't, click the spot you want to remove on the image to sample that color as the key color with an eyedropper. You can also use presets — white, black, green screen, blue screen, magenta — or choose any color with the color picker. Raise the "tolerance" to also remove colors close to the key color, which helps with JPEG noise or a slightly uneven background. Raise "edge softness" to add a semi-transparent band just outside the removed color, smoothing jagged outlines (aliasing) so the subject's edge blends into whatever you place behind it. The result updates live on a checkerboard preview that shows the transparent areas, and the percentage of the image made transparent is displayed. The export is a PNG with the alpha channel preserved, so you can drop it straight onto slides, e-commerce product images, Discord/LINE sticker bases, or thumbnail assets. It isn't meant for hard cutouts like fine hair or semi-transparent glass, but it's great for quickly knocking out a flat background behind a logo, icon, illustration, or shape. Your image is your work or your product, so this tool uploads nothing — loading, removing the color, and downloading all happen locally in your browser.
How to use
- Drop the image whose background you want to remove (or click to choose, or paste with Ctrl/Cmd+V). The background color is auto-detected.
- If it doesn't drop out, click the area you want gone to sample its color, or pick the key color from the presets / color picker.
- Tune "tolerance" and "edge softness", check the checkerboard preview, then click "Download PNG" to save the transparent image.
FAQ
Are my images uploaded to a server?
No. Loading the image, removing the color, and downloading all happen in your browser. Nothing is uploaded, stored, or sent anywhere — everything is processed only on your device.
What images does this work best on?
Flat, single-color backgrounds such as a white background or a green/blue screen. It's great for quickly knocking out the background behind logos, icons, illustrations, shapes, and product shots. It struggles with fine edges like hair, subjects similar in color to the background, and strong gradients (it's a simple chroma key).
How do I choose which color to remove?
The background color is auto-detected when you load the image. If it's off, click the area you want gone on the image to sample that color with the eyedropper. You can also use the white / black / green screen / blue screen / magenta presets, or pick any color with the color picker.
What do "tolerance" and "edge softness" do?
"Tolerance" controls how far from the key color a pixel can be and still be removed — raise it to clear JPEG noise or an uneven background, but too high will eat into your subject. "Edge softness" adds a semi-transparent band just outside the removed color to smooth jagged outlines, so the subject's edge blends into the new background.
Is the exported PNG actually transparent?
Yes. It's exported as a PNG with the alpha channel preserved, so the removed area stays transparent and can be layered over any background. The checkerboard in the preview is just a way to show the transparent areas clearly.
Can I use a JPEG?
You can load a JPEG, but the output is a PNG because PNG supports transparency and JPEG does not. JPEG compression can make the background color uneven, so raising the "tolerance" a little usually helps it drop out.
