How to use Compress PDF
Open the Compress PDF tool, drop your file into the upload area, choose any settings that match your output needs, and start the browser-side processor. For live tools, the file is read with the File API and transformed locally.
The progress bar shows each stage while the page packages your PDF result. When processing completes, the download starts automatically.
Privacy
Because the workflow is browser-only, your original document is not sent to PlumFile servers. Refreshing or closing the tab clears the working file from memory.
