PNG color tone changer.

Each pixel is converted to hue, saturation and lightness. The tool keeps the pixel's lightness and replaces its hue and saturation with the tone color's, so dark areas stay dark, bright areas stay bright and everything shifts to one color. That is why the result keeps its depth instead of looking like a flat wash of color.

Pick the Sepia preset, #cca47d: a warm brown with modest saturation. The classic look comes from that hue over the image's own lightness, the way aged prints turned. Move the picker toward a darker brown for a stronger sepia or lower the strength for a faint one.

Pick a gray such as #808080, or any color with the saturation dragged to zero. With no saturation to apply, each pixel keeps only its lightness, which is a grayscale conversion with every shadow and highlight intact.

The color replacer finds one color and swaps it for another, leaving everything else alone. The tone changer shifts the whole image to one hue. Use the replacer to change one element; use this tool for a mood, a filter or a monochrome.

Fully transparent pixels are skipped and stay transparent. Partly transparent pixels get the new tone and keep their alpha value, so a logo or icon with a transparent background comes out toned on the same transparent background.

The picker opens with eight swatches: Sepia (#cca47d), Slate (#6b7280), Ocean (#2563eb), Teal (#0d9488), Forest (#15803d), Sunset (#ea580c), Rose (#e11d48) and Violet (#7c3aed). Any of them is a starting point; drag in the picker or type a hex code for your own tone.

Strength blends the toned pixels with the original ones. At 100 the image is fully toned; at 50 half the original color shows through, which reads as a tint rather than a monochrome; at 0 nothing changes. Lower it for a subtle cast, raise it for a full single-color image.

Yes. The picker has a hex field, so a brand color such as #1da1f2 can be typed in exactly and the whole image takes that hue and saturation. Note the code and apply it to every image in a set for a consistent look.

No. Your browser decodes the file and does the pixel work with its Canvas API, and the page makes no request with it. You can load the page, go offline and keep working; the download is written from memory on your device.

No. The PNG color tone changer is free and opens without a sign-in, an account or an install.

Nothing. The PNG color tone changer holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
