How PDF compression works

PDFDistrict Compress re-encodes your PDF to remove redundant internal data and optimize stream structures. For text-heavy documents this often produces a 30–60% reduction. PDFs made primarily of JPEG images may see more modest savings, since the images were already compressed when the PDF was created. The result is shown as a before/after comparison — if compression doesn't help, you can simply discard the output.

Private by design: PDFDistrict runs entirely in your web browser. No files are uploaded to any server. No account is required. Your documents stay on your device.
