Free Online PDF Tools

PDFStream is a free, browser-based PDF toolkit that handles every PDF task you encounter — without uploading a single file to any server. Every operation runs entirely in your browser using WebAssembly and modern JavaScript, so your documents stay private and under your control at all times. Whether you need to merge contracts for a deal, compress a report before emailing it, split a scanned book into chapters, or convert pages to images for a presentation, PDFStream has a dedicated tool built for the job. With over 60 tools organized into clear categories — Manage, Convert, Optimize, Security, Edit, Page, Watermark, and Extract — you can find exactly what you need in seconds. No account creation, no subscription, no watermarks, no file size limits imposed by a backend server. Just open the tool, drop your file, and get your result. PDFStream works on any modern browser — Chrome, Safari, Firefox, Edge — on desktop and mobile alike. For teams and individuals who handle sensitive documents, the local-processing model is a meaningful privacy guarantee. Legal documents, financial reports, medical records — none of these ever leave your device. PDFStream is built on the principle that a useful tool doesn't have to compromise your privacy.
