When PDF compression helps

  • Create a smaller copy for email attachments and online uploads.

Local PDF compression

Compression runs locally in your browser. The PDF is not uploaded to Blink 2 during the standard compression workflow.

PDF compression FAQ

How much smaller will my PDF become?

The result depends on the document. Image-heavy PDFs usually offer more room for reduction than text-only files.

Can compression reduce image quality?

Yes. Smaller files can require lower image quality, so review the downloaded result before sharing it.

Is the original PDF deleted or replaced?

No. Your original remains unchanged and the compressed version downloads as a separate file.
