Large PDF files are cumbersome to share via email, upload to websites, or store in cloud services with limited space. Compression reduces file size dramatically while maintaining document usability.
Email services typically limit attachments to 10-25MB. PDF compression ensures your documents stay under these limits without splitting files or using file-sharing services. Faster uploads and downloads also save time, especially on slower connections.
For web applications, smaller PDFs load faster, improving user experience. Document management systems and digital archives also benefit from reduced storage costs when files are properly optimized.
Minimal compression, best quality
Good balance of size and quality
Smallest file size possible
Image-heavy PDFs compress best. Scanned documents and photo-rich files can see 50-80% reduction.
Text-only PDFs are already efficient. Expect smaller reductions (10-20%) for documents without images.
Already compressed PDFs may not shrink much further. The best results come from unoptimized files.
Email attachments often have 25MB limits. Use Maximum Compression for files you need to send via email.
Reduce file size to fit within email size limits (typically 10-25MB).
Optimize PDFs for website uploads where smaller files load faster.
Save storage space by compressing archived documents.
Create smaller files that transfer faster over mobile networks.
Meet file size requirements for online applications and forms.
Reduce storage costs by compressing large document collections.
Compression varies by content. Image-heavy PDFs can shrink 40-80%. Text documents may only reduce 10-20% as they're already efficient.
No. Even Maximum Compression keeps text sharp and readable. Images may show some quality loss at highest compression, but documents remain usable.
Use High Quality for documents you'll print, Balanced for general sharing, and Maximum Compression for email attachments or size-restricted uploads.
Yes, but you may see minimal additional reduction. Already-optimized PDFs don't compress much further.
No. All compression happens locally in your browser. Your file never leaves your device.
