Common questions about PDF compression
Compression results vary depending on the original PDF content. Typically, you can expect 20-70% size reduction. PDFs with many images will compress more than text-only documents. The actual reduction depends on your chosen compression settings.
Yes, compression will affect quality to some degree. Higher compression levels result in smaller files but lower quality. We recommend using "High Quality" compression for important documents and "Maximum Compression" for drafts or when file size is critical.
We support PDF files up to 50MB in size. For larger files, we recommend splitting them into smaller sections first or using desktop PDF compression software. Processing time increases with file size.
Yes! All compression happens locally in your browser. Your PDF files are never uploaded to our servers or sent over the internet. The compression process runs entirely on your device for maximum privacy and security.
PDFs with high-resolution images, embedded fonts, and metadata compress best. Scanned documents and PDFs with many images typically see the largest size reductions. Text-only PDFs may not compress as much since text is already efficiently stored.
No, we cannot compress password-protected PDFs. You must remove the password protection before uploading the file. This is a security measure to ensure we cannot access protected content.
