Why browser-side?
Tools that run in the browser don't send your data anywhere — no upload, no logging, no terms of service to read. They're also faster (no round-trip), work offline once loaded, and have no daily limits. Every tool on this page uses HTML5 Canvas, WebCrypto, pdf-lib, pdf.js, or other native browser features to keep your files local.
