QKitBoxImage filters
Grayscale, invert, sepia, brightness and contrast — adjust with sliders, preview live, download when it looks right.
Drop an image, or click to choose
The sliders apply live on the preview.
How it works
Filters use the canvas 2D filter property — the same CSS filter functions browsers apply natively, so results match what a CSS-styled version would look like. The download bakes the filters into the pixels (a flat PNG), and the original file on your disk is never modified.
Frequently asked questions
Can I combine filters?
Yes — all five sliders apply together, in the standard filter chain order.
Is the output quality reduced?
No — the export is a lossless PNG at the original dimensions. For a smaller file, compress afterwards.
