How to Compress a PDF for Client Review
Optimize a review copy, preserve the details clients need, and make the version unmistakable.
Last updated
To prepare a PDF for client review, separate the review copy from the approved source and identify what the client must inspect. Use moderate compression, then test small text, drawings, comments, links, and page references in the downloaded result. Give the file a versioned name and share it through the client's approved channel with review instructions and a response deadline.
Preserve the information a reviewer will use
Client documents often mix dense text, drawings, screenshots, and annotations. A smaller file should not make a detail impossible to evaluate. Work from a duplicate, keep the source immutable, and confirm the sharing channel is approved for client material. PDFStay's standard compression is designed for the current browser session.1, 2
| Content | Risk after compression | Reviewer check |
|---|---|---|
| Plans, diagrams, or screenshots | Fine lines become unclear | Zoom into representative details |

FAQ
Should comments be flattened before compression?
Only if the approved review process requires it. Flattening can change how comments are edited or searched, so preserve a source copy and confirm the client's workflow.
What is the safest compression level for design reviews?
Start with moderate compression and inspect the smallest drawings and screenshots. Choose a lighter setting if a client must judge fine visual detail.
