Image Filter Editor

Quick photo adjustments (brightening a dim shot, desaturating a photo for a mood board, blurring a background, or converting something to black and white) usually mean opening a full desktop editor for a change that takes seconds. This tool applies the same kind of adjustments directly in your browser: upload an image, drag a slider, and see the result instantly, then download it once you're happy with it.

Seven adjustments are available as independent sliders: brightness, contrast, and saturation (each from 0-200%, with 100% being the untouched original), blur (0-20px), and sepia, grayscale, and invert (each 0-100%, layering a tint or full color inversion on top of whatever the other sliders already did). They combine freely: dialing up contrast, pulling saturation down, and adding a touch of sepia together produces a warm, faded look, while grayscale plus a contrast boost gives a classic black-and-white conversion.

The live preview is powered by the browser's own CSS filter effects, the same rendering path used for on-page filter effects generally, so dragging a slider updates the image instantly with no lag, no re-processing delay, and no loss of responsiveness even while actively dragging. When you're ready to download, the exact same adjustment is re-applied through the Canvas API's matching filter support, which bakes it permanently into the image's actual pixel data rather than just how it's displayed, so the file you download looks exactly like the live preview, with the adjustment now a permanent part of the image itself.

Every step (decoding the image, rendering the live preview, and baking the final file) happens locally using APIs already built into your browser. Your image is never uploaded, transmitted, logged, or stored anywhere, even for a moment.
