Change color of image & logo online

Change logo colors and image colors online free. Replace one color with another—logo color changer and PNG color changer with similarity control, in your browser.

What is a change color of image / logo color changer?

A change color of image tool (also called an image color changer, picture color changer, logo color changer, or color replacer) swaps one color for another inside a photo or PNG. People search for “change color of image”, “logo color changer”, “change logo color”, “image colour changer”, “png color changer”, and “replace color in image” when a logo or graphic needs a new brand color without opening Photoshop. This free online tool matches a From color (plus similar tones), replaces it with a To color, can preserve shades, and downloads PNG—all in your browser. For a full-image tint wash, use Colorize Image instead.

Image color changer features

Selective color replace for photos, logos, and PNGs.

  • From → To color swap

    Replace a chosen color with another hex / picker value.

  • Similarity matching

    Include nearby shades so edges and gradients swap cleanly.

  • Preserve shades

    Keep lightness so highlights and shadows look natural.

  • Match preview mask

    Highlight which pixels will change before you commit.

  • PNG-friendly

    Alpha is left alone—ideal for logo and icon recolors.

How to change logo or image color

Recolor a PNG logo or picture in a few steps.

  1. Upload the logo or image

    Drop a transparent PNG logo, icon, or photo (15 MB max).

  2. Pick From and To

    Set the brand color to find and the new color to apply.

  3. Tune similarity

    Raise Similarity and optionally preview the match mask.

  4. Download

    Turn off the mask preview and save the recolored PNG.

Tips for changing image colors

Cleaner replaces and fewer leftover pixels.
  • 01

    Start with low similarity

    Raise gradually until edges fill without eating neighboring colors.

  • 02

    Use the match preview

    Magenta mask shows exactly what will swap before you download.

  • 03

    Prefer flat PNGs for logos

    Solid fills replace more cleanly than noisy photos.

  • 04

    Need a global tint?

    Switch to /colorize-image for a whole-image wash toward one color.

Technical details

How this image color changer works.
Matching
Euclidean RGB distance from the From color; Similarity scales the match radius.
Preserve shades
Keeps source lightness (HSL L) while applying destination hue/saturation.
Alpha
Transparent pixels (alpha < 8) are skipped; PNG transparency is preserved.
Limits
15 MB upload; 8192 px max edge; 100% client-side Canvas 2D.
