Step-by-step instructions

  1. Upload the source PDF into the Compress PDF tool.
  2. Choose a compression level based on your goal: email, web upload, or storage.
  3. Review the output and confirm that text, charts, and scans still look acceptable before sharing.

Best use cases for aggressive compression

Aggressive compression works best for oversized scan bundles and image-heavy PDFs where transport speed matters more than pixel-perfect fidelity.

When not to over-compress

Avoid heavy compression for legal documents, contracts, and tables with fine print. Smaller files are not worth it if users have to zoom and guess at the text.

FAQ

Can I compress a PDF to 1MB exactly?

You can target that outcome with size-focused landing pages and presets, but the actual result depends on the content inside the original PDF.

Why do scans shrink more than text PDFs?

Scanned PDFs often contain large raster images, which have more room for optimization than text-first office documents that are already efficient.
