Higher compression levels result in smaller files but may reduce quality slightly
Reduce PDF file size online for free. Our intelligent compression maintains quality while significantly reducing file size. Perfect for email attachments and web uploads.
Compression ratio depends on the original PDF content. Text-heavy PDFs compress less (10-30%), while image-heavy PDFs can be reduced by 50-90%. Our intelligent algorithm optimizes each file automatically.
Quality impact varies by compression level. Low and Medium levels maintain excellent quality. High compression may show slight quality reduction on images. Maximum compression prioritizes file size over quality.
Free users can compress PDFs up to 100MB. Pro users can handle files up to 500MB. Very large files may take longer to process.
You'll need to remove password protection before compression. Use our PDF password remover tool first, then compress the unlocked file.
Most PDFs compress in 10-30 seconds. Larger files (50MB+) may take 1-2 minutes depending on content complexity and chosen compression level.
