1
Upload your PDF
Drag and drop the PDF you need to email, or click to browse.
2
Choose compression level
Select a compression preset. For email, medium or high compression usually works best.
3
Download the smaller PDF
Click "Compress" and download. Most email services accept attachments up to 25MB.

Most email providers (Gmail, Outlook) have a 25MB attachment limit.
If the PDF has many high-resolution photos, compression can reduce it by 50–80%.
Consider splitting a large PDF into multiple parts if compression alone isn't enough.

What's the typical email attachment limit?

Gmail and most providers allow up to 25MB. Outlook allows 20MB. Corporate email systems may have lower limits.

Will the recipient see any quality difference?

For most documents, the quality difference is negligible. Text remains sharp — only embedded images are optimized.

Can I compress multiple PDFs at once?

Yes, use the Batch Process tool to compress multiple PDFs simultaneously.
