Lightcraft: Free RAW Photo Editor in Your Browser | Morph

Lightcraft is a photo workflow in your browser: import a folder, cull it, rate and flag the keepers, then develop them with non-destructive adjustments — the job a photographer opens a desktop catalog for. It reads JPEG, PNG and HEIC as well as RAW files from Canon, Nikon, Sony and the DNG standard. Adjustments are stored as edit metadata in your browser; the original file is never touched, and never uploaded.

The two modes you will live in

Library — a catalog grid and filmstrip of everything you imported, with star ratings (0–5), pick and reject flags, and smart collections by date. The shortcuts are the ones photographers already know: 1–5 to rate, P to pick, X to reject.
Develop — panels for Basic, Light, Color, Effects, Detail, Optics, Geometry and Masking. Every slider stacks as an instruction on top of the original pixels, so you can undo any step later.

Assisted culling

A burst of thirty near-identical frames takes minutes to cull by eye. Lightcraft's Assisted Culling groups similar shots, scores each on sharpness, eye contact and exposure, and recommends the keeper. The model runs in your browser — the photos are not sent to a server to be scored.

Why the browser is the right place for this

A RAW workflow is the last thing most people expect to work in a web page, because it is the last thing most web apps would dare to do without uploading. Lightcraft decodes the RAW on your machine, renders the preview with your GPU, and keeps the catalog in your browser's storage on your disk. The upside is not only privacy: there is no upload of a 30 MB file per photo, so a shoot of a thousand frames opens as fast as your drive can read it.

How to use

Open Lightcraft — Go to morph.cool/lightcraft. It loads in the browser with no installation.
Import a shoot — Drop a folder or a selection of photos — JPEG, PNG, HEIC, or RAW (CR2, NEF, ARW, DNG). They are read on your device into the Library.
Cull — Move through the grid with the arrow keys. Press 1–5 to rate, P to pick, X to reject. Turn on Assisted Culling to let the model group bursts and suggest the keeper.
Develop — Open a keeper in Develop. Work down the panels — exposure and contrast, colour, effects, detail, optics, geometry — and mask an adjustment to part of the frame. Every change is non-destructive.
Export — Export the developed photos as JPEG, PNG or WebP at the size you need. The renders are produced on your machine and saved to your disk.

Frequently asked questions

Is Lightcraft free?

Yes. Open it and edit a shoot with no account. Morph Pro adds the limitless version of every pro program.

Does it upload my RAW files?

No. RAW decoding, preview rendering and export happen on your device. The catalog and your edits live in your browser's storage, on your own disk.

Which RAW formats does it read?

Canon CR2, Nikon NEF, Sony ARW and DNG, alongside JPEG, PNG and HEIC.

Are my edits destructive?

No. Adjustments are stored as metadata on top of the original pixels. The source file is never changed and every step can be undone.

Does it replace a desktop catalog?

For culling, rating and developing, it covers the everyday workflow with the same shortcuts. Map and Print modes are planned for a later version.
