When to Use Each Compression Level
Low: Client-facing documents, presentations. Medium: Email attachments, web uploads. High: Archival, bulk storage.
What Affects PDF File Size
Images: High-resolution photos are the biggest factor. Fonts: Embedded fonts add size. Layers: Transparent layers increase file size. Pages: More pages = larger file.
