PDF guides
Longer answers to the questions that come up before and after you use a tool: how compression actually works, what is really at stake when a contract gets uploaded, and how to assemble one clean PDF out of a stack of scans.
All guides
How to reduce PDF size without losing quality
Which part of a PDF is actually large, which compression settings are invisible on screen, and how to tell when a file is already as small as it should be.
Why you should not upload contracts to a free PDF site
Free PDF sites have to process your file somewhere. For contracts, ID scans and medical letters, that trade is worse than it looks.
How to combine scanned documents into one PDF
Scans follow their own rules: huge image pages, blank backs, mixed sizes, sideways pages. How to merge them into one clean PDF without re-scanning.
