Apply filters like grayscale, sepia, invert, blur

What this tool does

Apply basic canvas filters and export a PNG. Brightness, contrast and saturation sliders produce canvas filter multipliers. Grayscale, sepia, inversion or a 4-pixel blur preset is applied after those slider filters. The filtered image is rendered at the original pixel dimensions and encoded as PNG.

How to use Image Filter

  1. Prepare the input. Choose a small image.
  2. Run or configure the tool. Select a preset and adjust brightness, contrast or saturation.
  3. Check and use the output. Download Filtered PNG and inspect the result.

How this tool works

Brightness, contrast and saturation sliders produce canvas filter multipliers. Grayscale, sepia, inversion or a 4-pixel blur preset is applied after those slider filters. The filtered image is rendered at the original pixel dimensions and encoded as PNG.

Worked example

Input: 100 × 60 pixel RGB fixture; Grayscale preset; sliders at zero

Output: 100 × 60 pixel PNG with equal red, green and blue channels in each grayscale pixel.

Limits, assumptions and interpretation

Filter support and exact raster output depend on the browser canvas implementation.

  • PNG export is a new raster image; animation, metadata and the original profile are not preserved.
  • There is no explicit file-size/pixel guard here; large images can exhaust tab memory.
  • Blur is a visual effect, not a guarantee that sensitive details cannot be recovered or recognized.
