Lamina PDF
Create, read, edit and save PDFs from Rust and TypeScript. One core runs on servers, in browsers and at the edge.
Lamina PDF creates, reads, edits and saves PDFs. One Rust core does the work, and it runs natively and as WebAssembly in browsers, Node, Deno, Bun and Cloudflare Workers. It’s for apps that make documents, such as invoices, reports and tickets, and for apps that open documents other people send.
laminapdfon crates.io is the Rust crate. Its API reference is on docs.rs.@laminapdf/sdkon npm is the TypeScript API over the WebAssembly build. After oneawait init(), every call is synchronous, and the API is the same in every runtime. Its API reference is on this site.
