How to compress a PDF

  1. Attach the PDF you want to reduce.
  2. Select the quality and scale that fit your use case.
  3. Create and download the compressed copy.

Understanding the trade-off

Compression reduces file size by rendering pages into new images. Lower quality and scale can create a smaller result, while higher settings preserve more detail. Because pages are rebuilt, selectable text, links and interactive fields may be lost.

Choose the right document

This tool is best for scans, photo reports and PDFs with large embedded images. A digitally generated contract or spreadsheet may see little benefit and is usually better left unchanged.

Why did my file not become much smaller?

The original may already be optimized or contain mostly compact text and vector content.

Does FlowPDF upload the file?

No. Rendering and rebuilding take place in your browser.
