What is the maximum PDF size I can send by email?
Gmail allows up to 25MB as an attachment. Outlook supports up to 20MB. Many corporate email servers cap at 10MB. If your PDF exceeds these limits, compress it first.
Will compressing reduce the PDF quality noticeably?
For most documents, compression at 'medium' setting produces no visible quality difference. The tool targets image metadata and redundant data — text and vector content are not affected.
How small can I compress a PDF?
Typical reductions range from 30% to 90% depending on content. A 20MB PDF with many scanned images can often be reduced to 2–4MB.
