What this does

Compress PDF reduces file size by stripping unused metadata and re-packing the document's internal object streams. Smaller files mean faster uploads, lower email-attachment limits, and less storage.

When to use it

  • Email attachments that exceed the recipient's limit (often 25 MB)
  • Uploading to portals that enforce a size cap
  • Archiving a folder of PDFs without running out of cloud storage

Frequently asked

How much smaller will my PDF get?

It depends on what's in it. PDFs full of bloat metadata can shrink by 30-50%; well-optimized PDFs may already be near-minimum size.

Is image quality preserved?

Yes. Client-side compression doesn't re-encode images — it only optimizes the PDF's internal structure. Deep image re-compression requires a server-side compressor, which is on the roadmap.
