How to Compress a PDF for Email Without Losing Quality

Email providers and job portals often reject large PDF attachments. Compression helps—but the wrong approach (rasterizing whole pages) can blur text and charts.

Start with Best quality in Compress PDF. If the file is still too large, try Balanced or Smallest file on a copy and compare side-by-side. Keep the original.

Image-heavy scans shrink the most. Text stays vector-sharp; text-only PDFs may not get much smaller—consider Extract Pages or Delete Pages first if you only need some pages.

With All PDF Needs, Ghostscript WASM compresses in your browser, so drafts and contracts are not uploaded just to shrink them for email.
