PDFCompressor-CL 1.4

PDFCompressor-CL by MAY Computer is a fast, scriptable command-line utility for reducing PDF file sizes without sacrificing readability. Built for IT teams, developers, and power users, it fits seamlessly into automated workflows and CI/CD pipelines, making large documents easier to store, share, and archive.

Key features

• High‑quality compression: Downsamples and recompresses images, subsets and compresses fonts, removes unused objects, consolidates duplicates, and optimizes cross-reference tables for smaller, cleaner PDFs.
• Smart image handling: Set minimum DPI thresholds, choose lossy or lossless recompression, and exclude vector graphics and text from modification to preserve clarity.
• Presets and profiles: Use ready-made presets (Lossless, Balanced, Maximum) or define custom profiles for consistent results across teams and servers.
• Batch and recursive processing: Compress single files, folders, or entire directory trees in one pass.
• Web optimization: Optional linearization (Fast Web View) for quicker streaming and page-by-page loading.
• Security-aware: Process password-protected PDFs (with the correct password), strip sensitive metadata, and optionally remove embedded files, JavaScript, and annotations.
• Reliable at scale: Multithreaded performance, consistent exit codes, verbose logging, and optional JSON output for easy integration and monitoring.
• Robust handling: Validates PDFs, attempts safe repairs on minor structural issues, and preserves searchable text and OCR layers.

Example usage

• Compress a single file with the Balanced preset:
  pdfcompressor-cl input.pdf -o output.pdf --preset balanced
• Batch compress a folder, keeping structure:
  pdfcompressor-cl ./invoices --recursive -o ./invoices_optimized --preset maximum
• Preserve images above 300 DPI and linearize for web:
  pdfcompressor-cl report.pdf -o report_small.pdf --min-image-dpi 300 --linearize
