How to Replace Colors in a PNG Image (Free, No Photoshop)

The tool scans every pixel in your PNG and groups colors by similarity. The result is a palette sorted by frequency — the most common colors appear first. Click any color in the palette, choose a replacement with the color picker, and apply. The change is instant and fully reversible before you download.

If you have an icon set or illustration in your old brand colors and need to update them to a new palette, the Color Replacer handles this without Photoshop. Works best on flat-color PNGs — logos, icons, and vector-exported illustrations where colors are solid and well-defined.

• Replace the primary brand color across the entire image in one click.
• Queue multiple replacements and apply them all at once — useful when a rebrand involves changing 3–4 colors simultaneously.
• Transparency is preserved throughout — no alpha channel damage.

If your image has a solid-color background (blue, grey, green, etc.), you can replace it directly with the Color Replacer — faster than running the AI background remover when the background is a simple, uniform color. Select the background color from the palette, set the replacement to white, transparent, or any target color, and apply.

For A/B testing product variants or creating color options for an e-commerce listing, process the same image multiple times with different color replacements. Start with your source image, replace the product color with variant A, download — then repeat for variants B and C. The whole process takes seconds per variant.

The Color Replacer works best on flat-color illustrations, icons, and logos. There are two common cases where it struggles:

• Photos and gradients. Photos contain thousands of unique color shades. Replacing a "blue sky" means many slightly-different blue pixels — replacement will create visible banding where gradients used to be smooth.
• Anti-aliasing artifacts. Edges between colors in a PNG often contain intermediate shades (anti-aliasing). These may be grouped with the main color or appear as leftover fringe after replacement. The Min. color % slider helps manage this.

The Min. color % slider hides colors that appear on less than X% of the total pixels in the image. Setting it to 1% filters out colors that cover less than 1% of the image — this typically removes anti-aliasing artifacts and one-off shades from the palette, leaving only the main colors you actually want to replace.

If you are working on a logo with a white border and a few brand colors, setting Min. color % to 2–5% gives you a clean palette of just the main colors without noise.
