Frequently asked questions
How does it compress?
Each page is re-rendered as a JPEG at a lower resolution and quality, then rebuilt into a new PDF. This trades some quality for size.
Will text stay selectable?
No. Pages become images, so text is no longer selectable or searchable after compression.
What if the file is already small?
If compression would make it larger, FileKit keeps your original and tells you.
