Photo editing without a server in the middle
Most online photo editors work like a remote desktop. You send the file, a server processes it, and a preview comes back — which is why they ask you to register, why file sizes are capped, and why many people hesitate before opening a client’s photo in one. The image tools here are built the other way round: the editor, including the code that decodes the file, is compiled to WebAssembly and runs inside your browser tab. The image is read from your disk, rendered on your machine, and saved back to your disk.
The three apps split the work the way a desktop image suite would. PhotoCraft is the layered editor — adjustments, masks, layer styles, type and shapes — and it opens PSD documents as layers, with basic PSD support. LightCraft is the RAW developer: it reads DNG, CR2, CR3, NEF and ARW files using its own Rust decoders rather than LibRaw, and writes JPEG, 16-bit TIFF or DNG. VectorCraft is the vector editor: a pen tool and editable paths over SVG, exporting clean SVG or rasterised PNG.
Where a format travels only one way, this page says so. PhotoCraft opens PSD files but does not export them — the honest limits are in the format table below, not discovered after an hour of editing.
