When to use it
When a file is too heavy to email or upload to a government portal, job site or chat app. Scans and image-heavy files often shrink by 50–90%.
Choosing a level
Balanced keeps images sharp enough to print; Stronger suits on-screen reading. Text always stays crisp because only the images inside are recompressed.
Good to know
Text-only files (exported from Word) are usually small already and won't shrink much. Check the estimated size and keep the original if you need high-quality prints.
