Make Photo Colors More Vivid

Raise the saturation to make muted photo colors richer, preview the change, then save a JPEG.

How to make photo colors more vivid

  1. Upload one image or PDF.
  2. Move the Color boost slider and check the preview. It starts at 35; 0 keeps the original colors and 100 is the strongest boost.
  3. Download the JPEG.

What you can upload and what you get

  • One PNG, JPEG, WebP or GIF image, or a PDF, up to 100 MB. Only the first PDF page or GIF frame is used.
  • Transparent areas are filled with white before the change is applied.
  • Large images are resized automatically to fit 4 million processing pixels and 8,192 pixels per side, keeping their proportions. Smaller images are not enlarged. You get a high-quality JPEG; original file metadata is not kept.

Questions

Will it change the brightness or the colors themselves?

The control adjusts saturation. Grays, black and white stay neutral. Strong boosts can clip color channels, changing shading or apparent brightness in already vivid areas.

Why do very bright colors lose detail at high settings?

Colors that are already close to full strength can reach the limit of what a JPEG can show, so fine shading in strong reds or oranges can flatten. Use a lower setting for photos that are already vivid.

Can it repair a faded or damaged photo?

No. It strengthens the colors that are already there; it does not restore missing color, remove scratches or add detail.
