StackTools offers a suite of free, privacy-focused browser applications designed to handle tasks like PDF and image processing directly on your device. With tools such as StackPDF and StackImage, users can merge, split, compress, convert, and enhance PDFs and images without uploading files to external servers. This approach ensures that sensitive documents and images remain private and secure, as all processing occurs locally in the browser. The tools are fast, free, and require no sign-up or internet connection after the initial load.
