Questions
Compress PDF FAQ
Will PDF compression make text blurry?
Best Quality focuses on lossless optimization. The smaller presets mainly reduce embedded image resolution, so text generally remains sharp while image quality may change.
What if compression makes the file larger?
DocuDense preserves the original bytes instead of replacing the document with a larger candidate.
