Show HN: Make PDFs look scanned (CLI or in the browser via WASM)
Summary
Show HN about make-look-scanned, a CLI tool that converts PDFs to look like scanned documents by rasterizing pages, applying a scan-like effect pipeline (skew, grayscale, grain, defocus, edge shadow, JPEG artifacts), and reassembling them into an image-only PDF. It also runs client-side in the browser via WebAssembly using the same effects, with a detailed CLI and browser workflow. The project is open source under AGPL-3.0.
