What Document Scanner does
Turn a photo of a document into a clean, cropped, deskewed scan or PDF. The result is a PDF, JPEG, PNG file you download directly.
How it works
Uses Canvas2D and WebGL2 with OffscreenCanvas for parallel processing. Filters run as GPU shaders where supported, falling back to CPU SIMD via WebAssembly. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
