Try a lower quality preset, or split the file and send two attachments.

Guide

Why compress PDFs

Shrink a PDF so it fits as an email attachment — balanced mode keeps text sharp while trimming image bulk.

  • Preset-driven quality control

    Choose balanced or aggressive presets knowing which one targets images vs structure. Text vectors stay sharp unless you explicitly choose a rasterizing path.

  • Email-ready outputs

    Shrink closing binders, scanned packets, and slide decks to fit gateway limits without splitting into awkward chapter files.

  • Pairs with merge and split

    Compress after merging exhibits or split before compressing only the image-heavy appendix — same browser session, same tool family.

compress PDFs use cases
  • Fit a signed contract under Gmail attachment limits.
  • Reduce scan DPI bloat from office MFPs before archival.
  • Compress slide PDFs exported from Keynote with full-bleed backgrounds.
  • Prepare court e-filing packets with strict megabyte caps.

FAQ

compress PDFs — frequently asked questions

Will compression blur text?

Text encoded as vectors remains vector data in balanced presets. Aggressive presets may recompress embedded images more heavily — inspect results before filing legal documents.

Can I compress scanned PDFs?

Yes — scans benefit most because they are image-dominant. Expect larger relative savings than on text-only briefs.

How do compression presets affect quality?

Balanced presets target embedded images while keeping vector text sharp. Aggressive presets trade more image quality for size. Sibling merge and split tools plus optional workspace storage support heavier production workflows.

Is there a file size limit?

Large files take longer. Split first if you hit browser timeouts on extremely heavy scans.

Does compression remove metadata?

Some redundant metadata may strip depending on preset. Do not rely on compression for redaction — use proper redaction tooling.

Can I batch compress?

Process one file per session in the free tool. Workspace users can chain operations across stored documents.
