ZeroCloudPDF

ZeroCloudPDF is a free, privacy first PDF toolkit that processes every file entirely inside your browser. Nothing is ever uploaded to a server, verified simply by disconnecting from the internet and confirming the tools still work. The suite includes converting images (JPG, PNG, WEBP, HEIC, GIF, BMP, SVG) and TIFF scans to PDF, compressing PDFs, merging multiple PDFs, converting Word documents to PDF, exporting PDF pages as JPG or PNG images, adding page numbers with full formatting control, signing PDFs by drawing, typing, or uploading a signature, and password protecting or unlocking PDFs using genuine 256 bit AES encryption via QPDF compiled to WebAssembly. Most tools run on pure JavaScript. Password protection, unlocking, and PDF signing use additional processing entirely inside the browser as well, nothing ever leaves your device. Built solo, bootstrapped, from India. No account required for any tool. No usage limits. No watermarks.
