Top Tips to Reduce PDF File Size Before Emailing

Managing PDF files efficiently saves time and avoids email bounce-backs and slow website loading.

Compress images in the PDF

Images are the main cause of large PDFs. Use medium compression (85% quality) — reduces size 40-60% with no visible change.

Remove unnecessary pages

Delete blank pages, draft pages or pages that do not need to be shared.

Flatten forms and remove metadata

Flattening forms and removing hidden metadata can reduce PDF size by 10-20%.
