About Compress PDF
Compress PDF is a free online tool that reduces PDF file size while preserving document quality. WayPDF's compression runs entirely in your browser using Canvas-based re-rendering — your files are never uploaded to any server. This is particularly important for confidential documents containing sensitive information.
Image-heavy PDFs (scanned documents, brochures, portfolios) typically see 60-80% size reduction, while text-only documents achieve 20-40%. Choose from three levels: Low for best quality, Medium for balanced compression, or High for maximum size reduction. Common use cases include compressing high-resolution scan batches for email attachment, reducing portfolio PDFs for job applications, and shrinking invoice archives for accounting systems.
Browser-based compression eliminates the need for server uploads and processing queues. Your document is processed instantly using your device's resources, making it both faster and more private than cloud-based alternatives.
