Make Color Transparent

Click a specific color in your image to erase it into transparency. Great for removing solid backgrounds, cleaning up logo backgrounds, and making icons transparent.

Erase the color you click

Click the color you want to remove and pixels of a similar color become transparent. Handy for quickly cleaning up logo backgrounds, solid-color icons, and white-background images.

Erase the color you click

Fine-tune what gets removed

Adjust the tolerance to also remove colors close to the one you clicked. Set it low for solid backgrounds, and a bit higher when there are shadows or color bleed for a more natural result.

Frequently asked questions

How do I make a color transparent?

Open an image and click the color you want to remove — pixels similar to it become transparent. For example, click the white area of a logo on a white background to make the background transparent. Keep in mind that edges may contain pixels that aren't exactly the same color because of anti-aliasing or shadows. In that case, raising the tolerance removes similar colors too, for a more natural result.

Which formats keep transparency?

To keep a transparent background, save as PNG or WebP. PNG supports transparent backgrounds reliably, while WebP keeps transparency while reducing file size.

Is it good for removing backgrounds?

It's well suited to solid backgrounds or backgrounds with a fairly uniform color. It works well when the color to remove is clear — like a logo on a white background, a solid-color icon, or a simple product-image background. For images with complex edges — hair, busy scenery, or backgrounds with many mixed colors — a single clicked color can't remove the background perfectly. This tool isn't AI background removal; it makes specific colors transparent based on the color you pick.

What is tolerance?

Tolerance sets how similar a color has to be to the one you clicked to be removed too. A low tolerance removes only pixels nearly identical to the clicked color, while a high tolerance removes somewhat different colors over a wider range.

ToleranceWhat gets removed
LowOnly pixels close to the clicked color
MediumAlso slightly different colors along the edges
HighMay remove shadows and color bleed over a wide range
Are my images uploaded to a server?

No. The image you choose is never sent to a server and is processed entirely in your browser. Picking the color, making it transparent, and generating the result all happen locally. That makes it safer to work with images you'd rather not upload — personal photos, work images, or document captures.

Is the original image kept?

Yes, your original image stays untouched. Making a color transparent doesn't modify the original file directly; it creates a new, transparent version for you to download. For example, removing the white background from logo.png leaves the original file as is and saves only the new, transparent result.

What if a white outline is left along the edges?

A white outline along the edges often comes from anti-aliasing or compression mixing in colors slightly different from the original background. Try raising the tolerance gradually and checking again. Raising it too far can erase important parts of the image, so start small and adjust slowly. If needed, clicking a few times to remove leftover color works better than removing everything at once.

Can I use it on mobile?

Yes, you can choose an image and make a color transparent in a mobile browser too. Selecting an exact pixel with a finger can be tricky, though, so precise work may be easier on a PC with a mouse. This tool includes a magnifier, so you can zoom in and pick colors more accurately on mobile as well.
