Frequently Asked Questions

Why use a size breakdown before compressing?
Because not all PDFs are large for the same reason. Knowing the main source of bloat helps you choose better next steps than applying generic compression blindly.
What kinds of elements usually cause PDF bloat?
High-resolution images, embedded fonts, attachments, duplicated resources, and overly complex page structures are common causes.
Can this help pick the right optimization tool?
Yes. A size breakdown tells you whether to remove images, downsample assets, subset fonts, split the file, or use another targeted workflow.
