Ever tried to email a crucial PDF, only to be blocked by a "file too large" error? Or waited impatiently for a document to upload to a web portal, watching the progress bar crawl? What if you could shrink your PDF to a specific kilobyte size
Key points
  1. Compressing PDFs reduces file size for easier emailing, faster uploads/downloads, and optimized storage without sacrificing important quality.
  2. Use the online tool by uploading your file, choosing a compression level based on your needs (extreme, recommended, or low), then download your compressed PDF within seconds.
  3. Different compression levels balance size reduction and visual quality: extreme for very small files (e.g., 50-100 KB), recommended for daily use, and low compression for professional visuals.
  4. The tool supports files up to 10 MB for free, works on all devices without software installation, and offers advanced features like batch processing and OCR for professional workflows.
  5. Security and privacy are prioritized with GDPR compliance, TLS encryption, automatic file deletion after 60 minutes, and ISO/IEC 27001 certification for data protection.
