Frequently Asked Questions

It depends on content. PDFs with many photos can shrink by 50–80%. Text-only documents see smaller reductions (10–20%) since text is already compact.

At the Balanced and High Quality levels, the difference is barely noticeable. Maximum Reduction may visibly reduce image sharpness, but text always remains clear.

You can, but each round yields diminishing returns. The first compression provides the biggest reduction. Re-compressing an already compressed PDF typically saves very little.

No. Compression never removes pages, text, or images. It only reduces the storage size of embedded images and optimizes internal PDF structures.

Balanced is recommended for most users — it offers significant size reduction while keeping images looking good. Use Maximum Reduction for email attachments, and High Quality when you need print-grade output.
