About PDF Tools
Everything CompressKits offers under PDF Tools is listed on this page: PDF Compressor. Each one is a finished tool rather than a demo — you add a file, the page starts from the setting it recommends for that particular file, and the result downloads straight back to you. Nothing is watermarked and nothing waits behind a signup.
These tools both read and write PDF. Without an account you can send files up to 200.0 MB, up to 5 of them in a single job, and take the results away one at a time or together as one ZIP. 5 ready-made settings cover the jobs people ask for most, so the manual controls are there for when a result needs adjusting rather than something to work through first.
If you would rather understand the trade-offs before running anything, the Learning Center has 3 guides in this category, among them Compress a PDF for Online Applications, Get a PDF Under 2 MB for Uploads: The Practical Guide, and How to compress a PDF (and why some barely shrink). Each one ends at the tool it describes, so reading and doing are never more than a click apart.
