FAQ
How much can I reduce a PDF file size?
Depends on content. PDFs with many images can be reduced 50–90%. Text-only PDFs compress much less — they're already small.
What is the maximum email attachment size?
Gmail: 25MB. Outlook: 20MB. Most corporate email: 10–25MB. Compress PDFs above these limits before sending.
Will compressing change the PDF content?
No — content is preserved. Only image resolution may be slightly reduced at high compression settings.
