PDF Compressor

Compress PDF file to get the same PDF quality but less filesize. Compress or optimize PDF files online, easily and free.

Introduction

Reduce the size of your PDF files without compromising quality. Our intelligent compression algorithm preserves the visual integrity of your documents while significantly reducing file size for easier sharing and storage.

Key Features & Benefits

Smart Compression Algorithms

Our compression engine analyzes your PDF and applies optimal compression techniques to images, fonts, and content streams. Choose Basic compression for moderate size reduction or Advanced compression for maximum savings without visible degradation.

Quality-Preserving Technology

Unlike basic tools that reduce resolution, our algorithms remove redundant data, optimize image encoding, and streamline PDF structure while keeping text sharp and images clear. Compressed PDFs remain professional and presentation-ready.

No Installation Required

Compress PDFs entirely in your browser without downloading software. Works on Windows, Mac, Linux, ChromeOS, and mobile devices. Simply drag and drop, select compression, and download your optimized PDF.

Batch Compression Support

Simultaneously compress multiple PDFs using batch processing. Upload up to 20 files at once for consistent compression—ideal for archives, email attachments, or website uploads.

Encrypted Processing

All uploads and downloads use secure SSL encryption. Files are processed in isolation and automatically deleted after one hour, ensuring privacy for sensitive documents.

Frequently Asked Questions (FAQs)

Compression results vary based on content. Image-heavy PDFs compress by 40-70%, text-heavy PDFs by 20-40%, and scanned PDFs often achieve the highest compression ratios.

Basic compression preserves original quality while reducing file size. Advanced compression minimally reduces image quality imperceptibly to the human eye but achieves greater size reduction.

Yes, but results may be limited. Previously compressed PDFs can still be optimized, but additional size reduction may be minimal. A comparison is always shown before finalization.

Absolutely not. Compression only optimizes storage; all pages, texts, images, and content remain intact and fully accessible after compression.

Free users can compress PDFs up to 50MB. Pro users can compress up to 500MB. Extremely large files should be split, compressed separately, and merged if needed.

Most PDFs compress in 5-20 seconds. Processing time increases with file size and complexity; large documents with high-resolution images may take up to a minute.
