Properly Size Images

Properly sizing images makes files easier to email, upload, and share. The best size is large enough to look clear, but not so large that it creates a heavy attachment.

Pick the PDF, image, or video you want to email. The size check is free.

Rather have us make the smaller copy?

What this page is for

Use this guide when photos, screenshots, or image-heavy documents are larger than they need to be. Oversized images can make PDFs, presentations, and email attachments fail even when the visible image looks simple.

A good resized image keeps the important detail while reducing pixel dimensions, file size, or export quality.

How to handle it

  • Check the current image dimensions and file size.
  • Resize images to the size they will actually be viewed or printed.
  • Use JPG for photos, PNG for graphics that need sharp edges or transparency, and PDF only when the final document needs pages.
  • Export a copy and compare it with the original before sending.
  • Use the file size checker if the image will be sent by email.

What to check before sending

  • Open the smaller file before sending it.
  • Check the final file size, not just the compression setting.
  • Keep the original file until the recipient confirms the smaller copy works.
  • Make sure important text, faces, forms, signatures, or charts are still clear.
