About PDF Compression
PDF compression re-compresses images embedded in a PDF file to reduce overall file size.
• Adjust image quality to balance file size and visual quality.
• Text and vector elements are preserved as-is.
• Text-only PDFs are already small and see minimal compression benefit.
• Processed directly in your browser — no files are uploaded to any server.
Usage Examples
FAQ
How does compression work?
It re-compresses images embedded in the PDF at the specified quality. Text and vector elements are not affected.
What quality setting should I use?
Generally, 60-80% offers a good balance. For printing, use 80% or higher. For screen viewing, 50-60% is usually sufficient.
Can text-only PDFs be compressed?
Text PDFs are already small, so additional compression has minimal effect. The biggest gains come from PDFs with embedded images.
