The fastest way to reduce the file size of a PDF is with a browser-based PDF tool that runs locally, keeps your data on your device, and skips the wait, watermarks and account walls that make bigger platforms slow. This guide walks through the four steps: open the tool, bring in your PDF, configure the run, and download a smaller PDF.
