The PDF tools you reach for at the worst possible moment: merge a stack of scans, pull pages 3–7 out of a contract, rotate the one page someone fed in sideways, compress to get under a mail limit, stamp a watermark, add page numbers, extract text or images. This is the kit where "no upload" matters most — PDFs are usually the ones with signatures and salaries in them.
What this kit does that a general converter doesn't.
The document you are merging is a contract or a payslip. It stays in the tab, which is the whole reason this kit exists.
