Questions
How much smaller will my PDF get?
Scans and PDFs full of photos usually shrink a lot, often by 50 to 90 percent. PDFs that are mostly text are already small and may barely change. Readily shows the exact result and keeps your original if it can't make the file smaller.
Will I still be able to select and copy the text?
With "Keep text selectable" on, yes. Readily only tidies the file's internal structure, which saves less. The stronger levels turn each page into a compressed image, so text can no longer be selected or searched.
Is my PDF uploaded?
No. Compression happens inside your browser on your own device.
