About PDF Compression
How does PDF compression work?
PDF compression reduces file size by converting each page into an optimized JPEG image, then reassembling those images into a new PDF. This is effective for documents containing high-resolution images, scanned pages, or embedded graphics. The trade-off is that text becomes non-selectable in the compressed version.
When should I compress a PDF?
Compress PDFs when you need to email large documents, upload them to systems with file size limits, or reduce storage usage. For text-heavy documents that are already small, compression may not provide meaningful reduction — the original is likely already efficient.
