How to use Color Splash Photo Editor

  1. Choose a photo. Flowers, clothing, and colorful objects against a quieter background work well. Start with the sample or open your own JPG, PNG, or WebP.
  2. Keep one or more colors. Choose Pick color and tap the part you want to keep. Turn on Add another color before picking additional colors, up to six. Hue range and Color tolerance control how much stays in color.
  3. Paint and refine. Paint color back restores the original color wherever you draw; Erase turns that area gray again. Paint only starts without a color-range selection. Clear selection returns the whole photo to black and white.
  4. Compare and save. Original, Black & white, Result, and Selection views help you inspect the work. Download PNG or JPG when you are happy with the result.

Frequently asked questions

Does this add artificial colors?

No. Selected areas keep the source photo’s original colors. Areas outside the mask use a luminance-based grayscale conversion.

Can I keep several colors?

Yes. Turn on Add another color and use Pick color for each additional range. Up to six ranges can be combined, and the brush can restore any other area.

Can I undo a brush stroke?

Yes. Undo and Redo cover the last 30 editing steps, including strokes, selection changes, and color adjustments.

Where are my photos processed?

On this device, inside your browser. Photos are not uploaded, and no account is required. Opening the website still makes ordinary page and asset requests.

Will my original files change?

No. Downloads are new copies. Photos, masks, and adjustments stay in this page session only; download your work before closing it.

Which images can I open?

JPG, PNG, and WebP, up to 15 MB and 16 megapixels per photo, with no side over 10,000 pixels. HEIC, RAW files, and animated images are not supported.

Does the download keep its resolution?

Yes. PNG and JPG downloads keep the oriented source width and height. PNG keeps transparency; JPG places transparency on white. Downloads are newly encoded pixels, not copies of the original metadata.

Can I undo an adjustment?

Undo and Redo keep the last 30 changes for each photo while this page stays open. Reset adjustments returns to the selected starting look. Selections and photos are not saved after you close the page.
