About Compress PDF
PDF too big for email? Pick a compression level -- low, medium, or high -- and shrink it down. Image-heavy files usually get 50-80% smaller, and the quality stays good enough that most people will not notice a difference. You will see the before-and-after file sizes right away.
Frequently Asked Questions
Compression results vary depending on the content. Image-heavy PDFs can often be reduced by 50-80%, while text-heavy documents may see 10-30% reduction.
On the balanced setting, the difference is barely noticeable. If you need pixel-perfect quality, use the low compression option -- it still knocks a decent chunk off the file size.
That is exactly what most people use this for. Try the high compression setting to get the file as small as possible.
Usually it is high-res images or embedded fonts. Documents with lots of photos or graphics tend to balloon in size. Compression targets those elements specifically.
No, compression never removes text, pages, or important content. It optimizes images and removes redundant data to make the file smaller.
