Large attachments often bounce back from email or fail on upload forms. PrimePDF compresses PDFs and images right in your browser.

Reduce PDF file size

Go to Compress PDF.

1. Choose Compress PDF for documents, or Compress Image for photos and graphics.
2. Upload your file (up to 100 MB).
3. Save the smaller file, or share it by email or link.

Reduce image file size

To reduce photo or graphic file size, open Compress Image.

Other ways to shrink a file

When compression alone is not enough, these tools can help reduce what you need to send:

• Split PDF
• Delete pages
• HEIC to JPEG
