What is LocalPDF?
LocalPDF is a free, browser-based PDF toolkit that offers tools for merging, splitting, compressing, converting, and annotating PDF files. Document operations happen locally in your browser using JavaScript and WebAssembly technology rather than a LocalPDF processing server.
Supported workflows process document bytes within your browser without uploading them to LocalPDF for processing. Device, browser, storage, download, and sharing risks remain separate.
