Upload your PDF to our free compressor, select Balanced mode (30-40% reduction) or Strong mode (50-70% reduction), and click Compress. Most PDFs will be reduced to well under email attachment limits in seconds.
Can I compress multiple PDFs for one email?
Yes! Compress each PDF individually using our free tool (3 per day on free tier, unlimited with Pro). Each compressed file downloads separately, and you can attach them all to your email.
Will the recipient notice the PDF was compressed?
For Balanced mode, most recipients won't notice any difference. Text remains perfectly sharp, and images maintain good quality. Strong mode may show slight image quality reduction on large photos, but documents remain fully readable.
What if my PDF is over 25MB and won't compress enough?
For very large PDFs, try our Pro plan which handles files up to 100MB. Alternatively, split the PDF into multiple parts, or use Strong mode with Target Size to get the most aggressive compression possible.
