Keep the compression slider at a low setting (20-40%) to shrink your file while preserving quality. Move it higher only if you need a much smaller file.
Click 'Compress PDF'. With low compression, your file size reduces but quality remains visually identical.
Click 'Download PDF' to save your shrunken file that still looks like the original.
Yes, using lower compression levels minimizes quality loss. For text-heavy PDFs, you can often achieve significant size reduction with virtually no visible quality difference.
We recommend starting with low to medium compression settings (slider at 20-40%). This typically reduces file size by 30-50% while maintaining original visual quality for most documents.
Not exactly. Lossless compression preserves every bit of original data but offers limited size reduction (typically 10-20%). Our tool prioritizes significant size reduction with minimal visible quality impact.
At lower compression levels, image quality degradation is barely noticeable to the human eye. At higher levels, you may see some softening or artifacts in photos and complex graphics.
Scanned PDFs are essentially images, so some quality trade-off may be necessary for meaningful size reduction. However, lower compression settings preserve good readability while reducing file size.
