Buyer's guide

How to choose a compress pdf

When picking a PDF compressor, check whether the tool imposes file size limits, requires sign-up, or shows ads during use. If you need to keep your documents private, look for services that auto-delete files after a set time or let you delete them manually. If you compress PDFs daily and want the most reliable, well-tested option, choose the tool with the highest user ratings and no subscription traps.
