Guide · Compress PDF
Optimize a PDF for reading on a phone
A 20 MB PDF opened on a phone over a weak mobile connection takes a long time to load, and many readers give up. On a small screen, stronger compression is rarely noticeable, which makes it a good trade-off for documents shared via a link or a newsletter.
Steps
- 1
Drop the original PDF into PDFly's Compress PDF tool.
- 2
Choose Strong: on a phone screen the difference in sharpness is rarely visible.
- 3
Click Run and compare the sizes. If the text looks too soft, start over with Standard.
- 4
Download the optimized PDF and share it. Since pages become images, keep the original for printing and searching.
