Quality boundary

Compression rewrites PDF objects for practical sharing. Image-heavy scans may change more than text-first documents, so compare the output before archival use.

Reduce PDF size without losing the details that matter.

The best compression result is not the smallest possible file. It is the smallest version that still keeps text, charts, signatures, and images useful for the way the document will be shared.

Choose a target before compressing

Start with the real requirement: an email attachment limit, a faster upload, or a lighter archive copy. Text-first PDFs often shrink differently from scanned documents because scans contain full-page images. Keep the original file, create a separate compressed copy, and avoid repeatedly compressing an already reduced result.

Check representative pages

Compare the output with the original at normal size and at 200% zoom. Review the page with the smallest text, the most detailed image, any barcode or signature, and any form or table that must remain readable. Confirm the page count and test search, links, and form fields when they are part of the document.
