Save every page of a PDF as a JPG image, at up to 300 DPI. Download pages one by one or all together in a ZIP file.
High suits screens and sharing. Use Maximum for printing or when small text must stay readable.
Convert the file, then download only the page you need. Or use Split PDF first.
JPG files are much smaller and accepted everywhere, including portals and messaging apps.
Everything happens in your browser. Your files are never uploaded to a server, so nobody else can see them.
