What’s inside

Eighteen filters, three families

Alongside the filters: soft local light with oval or brush layers, Soft Light and Overlay blending, a white-balance pipette and individual color controls. Each image keeps its own editable layers until the tab closes; exports combine them into the finished image.

Tone & light

Contrast that reads like a print — local tone, ink, glow, warmth and a vignette.

Photo realism

What a camera adds and a render lacks — grain, texture, highlight roll-off, fringe and softness.

Cinematic

Colour with intent — split tone, a graduated filter, film response and three-way colour.

How it works

Three steps, one window

Open
Drop one or several renders or photographs anywhere on the page, or choose files. Each image keeps its own edits.
Adjust
Tune the filters, compare before and after, and crop with a free or fixed ratio. Drag the frame to reposition it, zoom with the wheel and hold Space to pan. Reopen Crop to recover the original edges.
Save
Save one image at full resolution in JPEG, WebP or PNG, or save all images with their individual edits in a ZIP.

Private by design

Nothing leaves your device.

The filters are the desktop app’s own C core, compiled to WebAssembly. They run in your browser, across your processor’s cores. Images are never sent to a server or kept after the tab closes; saved presets and panel width stay in this browser.
