Why local processing?
Unlike classic online converters (upload → server → download), every fastPDF Web tool computes inside your browser.
Privacy by default
Contracts, invoices, theses, medical records — sensitive files should never land on a stranger's server. There is no server-side file storage here at all.
No queues, no waiting
No conversion queue, no "N people ahead of you". Speed depends on your own machine; small files finish instantly.
Free, without tricks
No watermarks, no hidden 2MB caps. The only limit on huge files is your browser's memory.
Target-size compression
Squeeze a PDF under an exact size (say 5MB) with multi-pass quality calibration — the same algorithmic idea as fastPDF for Mac.
