A monthly subscription renews automatically unless cancelled at least 24 hours before the end of the period. Manage or cancel your subscription in Settings. A note on compression: to make a PDF much smaller, its pages are saved as images, so text in a compressed PDF can't be selected or searched. Your original PDF is never changed — every tool saves a new file. Questions or an idea for the next update? Send feedback from Settings. I read everything and most updates start there.
