Which filters are available in the image filters tool?

The tool offers grayscale, sepia, invert and blur presets, plus a custom Adjust mode with brightness, contrast and saturation sliders from -100 to +100.

Are my images uploaded to a server when I apply filters?

No. The image is read into your browser and the filters are applied to a local canvas. Nothing is transmitted, so processing private photos is completely safe.

What image formats can I use?

Any image file the browser can decode. Images wider than 1000 pixels are scaled down for the working preview, and the filtered result always downloads as a PNG.

What do the brightness, contrast and saturation sliders actually do?

Brightness multiplies the pixel channel values by a factor (0 at -100, 2 at +100), contrast scales the difference from mid-grey, and saturation blends each pixel between its desaturated grey version and its full-colour version.

Why does the grayscale filter look better than a simple average?

The browser weights the red, green and blue channels roughly 0.299, 0.587 and 0.114, matching the human eye's sensitivity to green over red and blue. That produces a natural-looking black-and-white image instead of a muddy uniform grey.

Can I apply multiple filters at once?

The Adjust mode combines brightness, contrast and saturation together. One-click presets are applied one at a time, but you can chain a preset with Adjust by selecting Adjust and setting sliders after applying a preset.

Does the downloaded image keep the original resolution?

The download is delivered at the working width, capped at 1000 pixels for performance. If you need a larger or exact final size, use the image resizer on the export afterwards.

Why does the tool export only PNG?

PNG preserves the filtered pixels losslessly, which is important when you have deliberately adjusted an image and do not want an encoder adding artefacts. Convert to JPG or WebP afterwards when you need a smaller file.
