What "2 tasks a day" actually costs you
Smallpdf counts each operation as a task — not each session. A single document often needs more than one.
-
1
Merge three scanned pages into one PDF.
That's task 1 of 2 for the day, already spent. -
2
Realize the merged file is too large to email.
Compressing it is task 2 — the daily limit for an unregistered user. -
3
Need to password-protect it before sending?
You're now prompted to sign up for Pro — for a task that took two clicks.
On FastPrivatePDF, all three steps run back-to-back in your browser with no counter tracking you.
Stop risking your sensitive documents
When you use a typical "online PDF tool," you aren't just using a tool—you're trusting a company with your data. Your tax returns, signed contracts, and IDs are uploaded to a server, processed, and then "deleted." But "deleted eventually" isn't "private."
Fast Private PDF changes the architecture. By using the power of your browser's JavaScript engine (via pdf-lib and pdf.js), we process your files directly in your RAM. Your data never travels across the internet.
Same features, better philosophy
Whether you need to merge PDFs, split pages, or compress a file for an email, you get the same professional results without the corporate overhead or the privacy risks.
