What’s inside

Eighteen filters, three families

Each filter has its own settings, and they always stack in the same order, however you switch them on — so a look can be built up and taken apart again.

Tone & light

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

03Pro Contrast

05Bloom / Glow
06Brilliance / Warmth
07Vignette

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 a render or a photograph, or choose a file. Large files are fine — the preview works at screen size.
Adjust
Start from a look, then tune each filter. Drag the line for before and after, zoom with the wheel, check detail in the 100% loupe.
Save
The full resolution is written to JPEG, WebP or PNG, and the size of the file is shown before you save.

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 — there is no server to send the image to, and closing the tab leaves nothing behind.
