      Why SlimPDF exists

      Most PDF tools make files smaller at any cost — even if that means blurry text, charts, or diagrams.

      SlimPDF only optimizes when visual fidelity can be preserved. If it can't, your document is left unchanged.

      Built for humans today — and AI tomorrow

      Fidelity matters when PDFs are read by people and processed by machines.

      • Ingested into AI systems (search, knowledge bases, RAG)
      • Parsed for charts, tables, and figures
      • Indexed for retrieval without OCR artifacts

      Smaller files are good. Trustworthy documents are better.
