Paint Bucket Tool Online Free

Change Background Color with One Click

In this screen recording, the white background behind a person is replaced with a new color using a single click of the Paint Bucket tool . No selection, no masking, no layers - just click the area and it fills instantly.

Use the Tolerance slider to control how much of the similar color area gets filled - lower tolerance fills only very similar shades, higher tolerance spreads the fill across a wider range of colors. If the fill spills onto the t-shirt or other parts of the image, no worries - click Undo, reduce the Tolerance (around 20% is usually safe for cases like this), and click the background again.

Experiment and see what you can create. Download your edited image in the original size and quality. Since nothing is uploaded to our servers, your images stay completely private.

Color Mandalas and Line Art Digitally Online

In this screen recording, individual sections of a mandala are filled with color with just 1 click using our Paint Bucket tool so that each closed area between the black lines gets its own color instantly. This works with any line art, coloring pages, illustrations, vectors, photographs, or drawings.

Set Tolerance to a higher value like 60–70% to make sure that the color fills completely next to the black lines and no white area stays visible between the colors and black lines. Experiment with Tolerance slider to see which % works best for you. If a Tolerance is too high, the color might spread over the black outlines into the surrounding areas, no worries - click Undo, reduce Tolerance, and fill the color again.

Make a Toned Paper for Your Sketch

After turning your reference photograph into a pencil sketch in our Photo to Sketch Converter Online Free, upload the sketch here to our Paint Bucket Tool to create various colors for the background.

In this screen recording, you can see how the photo of grapes was easily turned into pencil lines and the background was filled using the bucket tool. The Tolerance slider was set to the maximum (100%), which means the color will spread more aggressively and fill everything that is the same color. In the previous example with the mandala, 100% Tolerance was too high because we wanted to fill small, specific areas, so the tool should be forced to spread less.

This way, you can create your own toned paper, such as Strathmore Toned Tan or Gray, or Pastelmat, and apply any background color you wish. Then you can print it on a paper and color over it using your favorite medium, or work over it digitally.

You can experiment with this tool and learn how Tolerance slider behaves. Use the Undo button and try again as much as you want - there is no limit on how many images you can upload or download. We also let you download your pictures at the exact same size as your original image, unreduced.
