Compress PDF — High Quality
Minimal compression that preserves maximum visual fidelity. Images stay at a crisp 300 DPI with 90% quality — virtually indistinguishable from the original. This preset is designed for documents going to print, professional presentations, photography portfolios, and any situation where image quality cannot be compromised. File size reduction comes mainly from optimizing the PDF structure itself.

FAQ
How much smaller will my PDF be?▾
With high-quality settings, expect a 10-30% file size reduction depending on the original PDF's structure. The savings come from optimizing internal PDF streams and removing redundant data rather than degrading images. For maximum reduction, use the Maximum Compression preset.
Is 300 DPI enough for printing?▾
Yes. 300 DPI is the standard resolution for professional printing including offset printing, digital presses, and inkjet printers. It ensures sharp images at any standard print size. Only large-format printing (billboards, banners) may require higher resolution.
When should I use high-quality vs other presets?▾
Use High Quality when the document will be printed, when it contains important photographs or artwork, or when it's a client deliverable where visual perfection matters. For documents viewed only on screen, the 1MB or 2MB presets offer better file size reduction with acceptable quality.
