Single PDF file

No image recompression, no quality loss. Savings come from removing redundant structure, unused objects, and metadata, then re-compressing the PDF's internal streams. Typically 5–30% depending on how the PDF was made.
Strip metadata
Removes title, author, subject, keywords, and producer/creator tags
Compact internal structure (object streams)
Combines and compresses the PDF's internal objects — usually the biggest lossless win
To hit an exact size, pages get re-rendered as compressed images if the lossless pass alone isn't enough. This can soften image/text sharpness — use it only when you need to fit a specific size limit (e.g. an upload cap).
