Evaluate PDF optimization with a before-and-after check

A large PDF may benefit from an optimization pass, but size reduction depends on its contents. A controlled comparison is more useful than assuming every file will shrink.

Prepare the input

Keep the input and write to a new path. Record the original size and identify pages with small text, detailed images, or unusual graphics for review.

These examples use local sample filenames. Substitute your own paths and check jetformat pdf optimize --help against the installed version before running the task. Put paths containing spaces inside quotes.

Run the command

jetformat pdf optimize book.pdf -o small.pdf

Optimization merges duplicate objects, compresses streams, and subsets fonts. It cannot promise a fixed reduction for a file that is already efficiently encoded.

Review before the next step

Compare output size, page count, text, and representative renders. A smaller file is not automatically acceptable, and some documents may show little or no size change.

Compare file sizes and render representative pages; accept the result only if readability and required behavior remain intact.

Keep the workflow repeatable

This operation uses page-based credits. Review the billing guide before processing a large document.

Keep the input revision with the result so a later reviewer can reproduce the decision. For a write operation, choose a new output path first; use overwrite flags only when replacing a previously reviewed result is intentional.
