Frequently Asked Questions
How much can I compress a PDF?
Compression depends on the PDF content. Light mode removes metadata and unused objects. Medium recompresses images. Extreme converts images to JPEG at 150 DPI for maximum reduction.
Will compressing a PDF reduce quality?
Light and Medium modes preserve visual quality. Extreme mode reduces image resolution to 150 DPI, which may slightly reduce image sharpness but significantly reduces file size.
