About PDFTasker

PDFTasker is a browser-only PDF tool. No upload, no signup, no surprises.

Why we built it

Most online PDF tools want you to upload your file to their server. Then sign up. Then watch some ads. Sometimes pay. For a job your browser could finish in three seconds.

We thought that was strange. So we didn't build it that way. PDFTasker is a PDF tool. Nothing more, nothing less.

Why are we shipping files to other people's servers?

Merging, splitting, signing, watermarking PDFs. Your browser can do all of it. It's been able to for years, thanks to WebAssembly and libraries like pdf-lib.

Most online PDF sites still ship your file to a server anyway. The reason is simple. That setup lets them track usage, push you toward a paid plan, and bolt on an account system. It's a business model, not a technical requirement.

We decided not to follow that model. That's the whole story.

Things we don't do

Here's a list of things PDFTasker doesn't do. Not a marketing pitch. Just facts.

  • We don't upload your files: Your file stays on your device. It's not a promise, it's the architecture. There's no upload code on the server side. There's no server side.
  • We don't ask you to sign up: No email field. No verification email. No password to forget. You open the page, you use the tool.
  • We don't do the AI thing: We're not AI-powered. We're not a next-gen anything. We looked at where an AI feature would actually help in a PDF tool, decided it wouldn't, and moved on. We're a PDF tool.
  • We don't lock features behind a Pro plan: All 16 tools work. There's no paywall, no upsell, no premium tier waiting to interrupt you mid-task.

How it actually works

PDF processing happens in your browser instead of in a cloud somewhere. To put it plainly: we use the computer you're already sitting at.

Open a file, do the work, save the file. That's the loop. The heavy lifting runs in a Web Worker so the page stays responsive even on large files.

  • No transfer, ever: Your file doesn't cross the internet. The client-side code is built that way. Even if we wanted to upload it, we couldn't.
  • Close the tab, it's gone: Everything happens in browser memory. Close the tab and there's nothing left. No leftover cache files. No log entries on our end.
  • Big files don't break it: Files over 100 MB get cached locally in IndexedDB so the browser doesn't choke. Still no server. The cache sits on your machine, not ours.

Where this matters

Sensitive documents are where this approach earns its keep. The work stays in your browser, so the file never has a chance to leave.

  • Contracts and legal docs: NDAs, agreements, confidential filings. Merge them, sign them. No detour through some company's server you've never heard of.
  • HR paperwork: Employee records, payroll, scanned IDs. Files that shouldn't leave your machine don't have to.
  • Tax and finance: Tax returns, bank statements, investment reports. Handled on your device. End of story.

A short note on privacy promises

Most PDF sites promise to delete your file after an hour. PDFTasker can't make that promise. There's nothing to delete. Your file never reached us in the first place.

Our privacy policy is short, too. Hard to write a long one when there's nothing to collect.
