Compress PDF reduces a document's file size so it clears the limits that keep bouncing it back — the attachment ceiling on an email, the upload cap on a job-application or government portal, the size a messaging app will accept. Instead of re-exporting from the original app, you shrink the finished PDF directly.
To reach a smaller size this tool re-encodes the pages as images at a lower quality. That's the tradeoff to understand plainly: the compressed pages become pictures, so the text on them is no longer selectable or searchable, and very fine detail softens. For a scanned document that's already an image you lose almost nothing; for a crisp text PDF, weigh whether you still need the text layer.
The whole process runs in your browser, so a confidential invoice or contract is never uploaded to a compression server. Try a setting, check the result, and re-compress until it fits.
