About fastPDF Web
An online PDF toolkit that treats privacy as a product principle and honesty as a discipline.
Why we built this
Most online PDF tools follow "upload → process on a server → download": your contracts, invoices and theses land on a stranger's server, and removing a watermark costs a subscription. We believe there's a better way — the modern browser is powerful enough to merge, compress, encrypt and convert files on your own device. Faster, more private, and it lets us avoid metering server compute.
Three product principles
1. Verifiable privacy
"Files never leave your device" is not a slogan: open your browser's network panel and watch zero uploads during processing. It is our first selling point and our first discipline.
2. Honest limits
Free tier: 20MB per file, 3 runs per day. Limits exist, appear only when hit, and describe real differences only. Capabilities that aren't ready are labeled "planned" instead of shipping fake tools.
3. Fidelity first
Better one tool fewer than one tool lying. Every B-tier tool states its fidelity ceiling in the UI; we don't pretend.
Where we are
34 live tools (all local) plus 117 honestly-labeled "planned" capability pages; bilingual Chinese/English. The desktop app fastPDF for Mac covers batch processing and Watch Folders. Business model: free-first, with a planned Pro tier (plans) — until payments exist, every tool is fully usable.
