1. Choose the right tool
Need a HEX value first? Use Color picker from image to read a pixel. Use Remove color to make matching pixels transparent, or Change color to replace their RGB color while keeping existing transparency. These tools do not cut out an object by understanding its shape.
2. Start with a precise selection
Upload a PNG, JPEG, or static WebP. Click the original preview to sample a color, or enter its six-digit HEX value. Set tolerance to 0 for an exact color match. Raise it gradually to include nearby colors along anti-aliased edges.
3. Protect other parts of the image
All matching pixels changes matching colors across the image. Connected area limits the edit to matching pixels that touch your selected point. For a white background and separate white details inside a logo, start with the connected option and a low tolerance. If the details touch the background through matching pixels, they may change too.
4. Check the result and export
Apply the edit, then switch between Original and Result. Use the checkerboard, white, and black preview backgrounds to inspect edges. Changing settings requires applying again before download. Your PNG keeps the decoded image dimensions.
When to use a different approach
Complex hair, shadows, gradients, and textured photographs may leave rough edges or lose detail. Color removal makes matched pixels fully transparent; color replacement writes one flat RGB color and keeps each pixel's alpha value. Neither tool identifies a subject or rebuilds a soft edge. Keep your original file and inspect the output at full size.
