Compress large PDFs to meet email attachment size limits while maintaining quality.
Optimize PDFs for faster web uploads and better user experience.
Reduce storage space for archived documents and backups.
Use light compression for documents with images, medium for general use, and high for maximum size reduction.
Balance file size reduction with quality requirements for your specific use case.
Always review compressed files to ensure quality meets your standards before sharing.
For best results, optimize images in your PDF before compression for maximum efficiency.
It resamples high-resolution images, subsets unused font glyphs, compresses content streams, and removes duplicate objects. Typical reduction is 40-80% depending on the original content.
Text and vector graphics remain sharp. Only raster images are resampled. The quality slider lets you control the trade-off between file size and image clarity.
Yes, but gains diminish. A previously optimized PDF may only shrink 5-15% further since redundant data has already been removed.
Lossless removes redundant data without quality loss. Lossy additionally resamples images to lower resolution for more aggressive size reduction — typically 60-80% smaller files.
Basic compression preserves metadata including author, title, and creation date. Some tools strip metadata as part of optimization — ours preserves it by default.
PDF compression reduces file size while maintaining document quality, making files easier to share, store, and upload. Our intelligent algorithms optimize various PDF elements without compromising readability or functionality.
This tool is particularly useful when:
