Photo Filters & Color Effects

What is this tool?

Photo Filters & Color Effects re-colours images with ready-made presets. Each preset is a colour transformation applied pixel by pixel, blended with the original by the Strength slider so you can go from a subtle tint to the full effect. Because the maths runs in the page itself, it behaves the same in every browser.

  • Making an old-photo or retro effect with Sepia or Vintage
  • Converting a colour photo to black and white
  • Inverting an image to make a negative
  • Quickly warming or cooling the tone of a picture

  3. 3Adjust brightness, contrast and saturation if needed
  4. 4Choose a format and click Download — several images arrive as a ZIP

Frequently asked questions

What filters are included?

Sepia, Vintage, Noir, Grayscale, Invert, Cool, Warm, Fade and Vivid, plus brightness, contrast and saturation controls that work with any of them.

Can I make the effect weaker?

Yes. The Strength slider blends the filtered result with the original, from 0% (unchanged) to 100% (full effect).

Does it keep transparency?

Yes, as long as you download PNG or WebP. JPEG has no transparency, so transparent areas turn white.

Will it process my whole folder?

Up to 50 images at once with the same settings, delivered as one ZIP.

Are my photos uploaded?

No. Filters are applied locally in your browser and nothing is sent to a server.
