Image Filter 🎨

About the Image Filter

The Image Filter runs entirely in your browser. Drop or select an image and use the sliders to apply grayscale, sepia, invert, blur, brightness, contrast, and saturation filters in real time. When you are happy with the result, download the filtered image as a PNG. Nothing is uploaded to a server — everything happens locally with JavaScript on your device.

Available filters

• Grayscale — Convert colors to shades of gray, 0 to 100%.
• Sepia — Apply a warm brown tint, reminiscent of vintage photographs.
• Invert — Invert the colors of the image.
• Blur — Apply a Gaussian blur, in pixels.
• Brightness — Adjust the overall brightness, 0 to 200%.
• Contrast — Adjust the difference between light and dark areas.
• Saturation — Adjust the intensity of colors.

Frequently asked questions

What is the output format? The download is a PNG file. This preserves transparency and avoids compression artifacts.

Are filters applied losslessly? The filter computation uses the browser's native canvas and CSS filter pipeline, which produces high quality results. The PNG output is lossless.

Does this tool upload my images? No. All filtering happens locally in your browser. Your image never leaves your device.

Can I combine multiple filters? Yes. All enabled filters are combined in real time, so you can mix grayscale with brightness, blur with contrast, and so on.
