About PDF compress
Shrink a PDF in your browser with Light, Balanced, or Maximum presets. Browser-side PDF compression may produce modest savings depending on the document.
How it works
Dockzio renders each page, recompresses it as JPEG at your chosen preset, and rebuilds a new PDF locally with pdf-lib.
Presets
Light keeps more detail, Balanced is the default tradeoff, and Maximum prioritizes the smallest file size.
Text & links
Compressed pages become images, so text is no longer selectable and interactive links are not preserved. Keep a copy of the original if you need those.
Privacy first
Everything is processed locally in your browser. Your documents are never sent to a Dockzio server.
