PNG color isolation

Remove Color from PNG Online

Choose a pixel in your PNG, control how closely nearby shades must match, and export a new transparent PNG at the original dimensions. Existing transparent areas stay transparent.

Pixel processing and PNG export happen locally in this browser. See the privacy details.

Work with the alpha channel

Remove color without flattening the PNG.

PNG files may already contain transparent pixels. The editor changes only the alpha of pixels matching your selected color; it does not place the image on a new background or convert it to a flat screenshot.

  1. 01

    Load the PNG

    Choose, drop, or paste the file. The browser reads its dimensions and transparency locally.

  2. 02

    Sample the color field

    Click a solid area away from antialiased edges, then inspect the checkerboard result.

  3. 03

    Tune only as far as needed

    Raise tolerance for compressed or shaded pixels; add softness only when the edge looks abrupt.

PNG sample / 04

A color field leaves the mark intact.

The project-made sample starts with transparent outer corners, a coral field, and a dark circular mark. Removing coral reveals transparency without changing the mark or the transparency already present outside the field.

PNG-specific jobs

Useful when transparency already matters.

This route is tuned for assets that need to remain PNGs, especially when their current alpha channel is part of the artwork rather than an accident.

  1. 01
    Interface assets

    Remove a flat export color from icons, badges, cursors, and UI overlays while keeping transparent padding.

  2. 02
    Texture and sprite elements

    Clear a known matte color around a small graphic without changing its pixel dimensions.

  3. 03
    Presentation graphics

    Prepare a logo or callout that must sit cleanly over different slide backgrounds.

PNG questions

Transparency in, transparency out.

The editor keeps PNG behavior explicit so existing alpha is not mistaken for a white background.

01Will existing transparent pixels in my PNG be preserved?

Yes. The removal engine can lower existing alpha but never makes a transparent or partly transparent pixel more opaque.

02Can I remove one color while keeping the PNG dimensions?

Yes. Export reruns the same settings at the original width and height and downloads a PNG with those dimensions.

03Why does a colored fringe remain around the PNG artwork?

Edge pixels are often blended with the old field color. Increase tolerance gradually, then add a small amount of Edge Softness if the transition is still hard.

04Can I remove only one connected area in a PNG?

Yes. Choose Connected area when the same color appears elsewhere and only the region touching your sampled pixel should disappear.

05Is the PNG uploaded for processing?

No. Decode, preview, color matching, and export occur in your browser. The file is not sent to RemoveColor.
