The Bitgrain editor

The editor is the fast surface: open a photograph, develop it, stack effects on it, export it. It handles around thirty camera RAW formats along with HEIC and HEIF from iPhone, TIFF and DNG, and it decodes all of them on your own machine rather than on a server.

Developing and grading

RAW files are demosaiced and developed in the browser with exposure, white balance, contrast, highlight and shadow recovery. Thirty eight film and cinematic LUTs cover the usual references, including Portra 400, CineStill 800T, Kodachrome and Tri-X, alongside grain, haze and bloom.

Export is genuine HDR when you want it, in BT.2020 and PQ, and ordinary PNG, WebP or JPEG when you do not. Batch mode runs a whole shoot through one effect chain and returns a ZIP.

The effect stack

Effects are stackable and order matters. Fourteen dither algorithms, halftone in mono, colour and CMYK, ASCII and Braille conversion, Sobel edge detection, crosshatch, ink wash, manga screentone, glitch, duotone, cyanotype and twenty four hardware and print palettes.

Every one of them is a classical algorithm with no model behind it, so the same photograph with the same settings gives you the same pixels on every run and on every machine.

Where the work goes

Export as PNG or WebP for screen, SVG when the artwork needs to scale or drive a pen plotter, or a ZIP of per-ink layers when it is going to a riso studio or a screen printer.

Projects save as a portable .btg file carrying the effect chain, so a look you build once can be reapplied to a whole series later without drift.

Working non-destructively

The effect chain sits on top of the developed image rather than replacing it, so you can reorder, retune or remove any stage at any point. Order genuinely matters: a dither applied before a halftone gives a completely different result from the reverse, and being able to drag one above the other is how you find out which you want.

The brush tool applies any effect selectively, so a halftone can sit on the background while the subject stays clean, or grain can be concentrated where a photocopy would have degraded first.

Common questions

Are my photos uploaded when I use the editor?

No. RAW decoding, effects and export all run in your browser through WebAssembly and Canvas. The file never leaves your machine for the core editing flow.

Which file types can I open?

Around thirty camera RAW formats including CR2, CR3, NEF, ARW, RAF, ORF, RW2 and DNG, plus HEIC and HEIF from iPhone, TIFF, PNG, JPEG and WebP.

Is the editor free?

Yes, with unlimited exports at web resolution with a watermark. Pro removes the watermark and unlocks full resolution, SVG, HDR and batch export for a single payment.
