Tips for Sending PDFs by Email
- Use Balanced compression — reduces file size by 40–70% with minimal quality loss
- Check the recipient's limit — corporate and government systems often have strict limits
- Split large PDFs — use our split PDF tool to divide a big document into smaller parts
- Remove unused pages — strip unnecessary pages before compressing
- Use cloud links as backup — if the compressed file is still too large, upload it to Google Drive and share the link instead
For maximum size reduction, try the "Small" compression setting which reduces images to 72 DPI — ideal for PDFs that will only be read on screen. For printed documents, use "Balanced" to maintain reasonable print quality. You can also learn more about reducing PDF size with our detailed guide.

Frequently Asked Questions
What is the maximum PDF size for Gmail?
Gmail allows email attachments up to 25MB total. However, many corporate and government email systems have lower limits, often 10MB or less. Using PDFix to compress your PDF first ensures it will go through.
How do I make a PDF smaller for email?
Upload your PDF to PDFix, select the 'Balanced' or 'Small' compression setting, and download the compressed version. Most PDFs shrink by 40–70% using this method.
Will my PDF look different after compression?
Text remains crisp at all compression levels. Images may show slight quality reduction at the lowest setting (Small/72 DPI), but remain fully readable. The Balanced setting is usually indistinguishable from the original.
What if my PDF is still too large after compression?
Try using the 'Small' compression level for maximum reduction. Alternatively, split the PDF into smaller sections using our split tool and send them in separate emails.
