Our mission

Make private PDF tools the obvious choice

We believe the most common PDF tasks shouldn't require handing your documents to a stranger's server. PDFNEO exists to make on-device processing fast, free, and effortless — so privacy is never the inconvenient option.

One principle, no exceptions

Your documents are yours. They're processed on your device, and they never touch our servers — because there are no servers handling your files.

Origin

Why we built PDFNEO

Working with PDFs online usually means uploading them somewhere. For a meme that's fine — for a signed contract, a payslip, or a scan of your passport, it isn't.

Modern browsers are remarkably capable. With WebAssembly and Web Workers, the same operations that used to need a server can run instantly on your own machine. PDFNEO is built on that idea: do everything on-device, and never upload a thing.

The difference

Why client-side processing matters

When a file never leaves your device, an entire category of risk simply disappears.

Nothing to breach

There is no server holding your documents, so there's no database for an attacker to compromise.

Nothing retained

No copies linger in a cloud bucket or backup. Close the tab and the file is gone from memory.

Nothing shared

Your data is never transmitted, so it can never be sold, profiled, or handed to a third party.

Nothing to wait for

No upload or download round-trip means results are effectively instant.

What we stand for

Our principles

A few commitments shape every decision we make about the product.

Privacy is the default

Files are processed on your device and never uploaded. Privacy isn't a setting you opt into — it's the architecture.

No gates, no friction

No sign-up, no email wall, no premium lock on core tools. Open a tool and get to work immediately.

Clean output, always

We never stamp watermarks or impose hidden limits. What you export is exactly what you made.

Built on open foundations

The heavy lifting runs on trusted open-source engines like pdf-lib, pdf.js, and Ghostscript compiled to WebAssembly.

Fast by design

Processing happens locally, so there's no upload queue and no waiting on a network round-trip.

Works offline

Once a tool loads, you can disconnect entirely and keep working — it's a true on-device app.

Under the hood

How PDFNEO works

The flow is the same for every tool, so there's nothing new to learn.

01
Pick a tool
Choose the job you need done, from merging and splitting to compression and conversion.
02
Add your files
Drag them in or browse. They load into your browser's memory and stay on your machine.
03
Download the result
Adjust the options, run it, and save the finished PDF instantly. Nothing was ever uploaded.

Built right

Performance first, privacy first

Speed and privacy usually trade off against each other. On-device processing gives you both.

Performance first

WebAssembly runs near-native speed in a background Web Worker, so the interface stays smooth even on large documents.

Privacy first

There is no backend that accepts documents. With no server in the path, there's nothing to breach, retain, or share.

Frequently asked questions

Is PDFNEO really free?

Yes. The core tools are free to use with no account, no watermarks, and no usage limits. There is no premium gate on the everyday PDF tasks.

Do I need to create an account?

No. There is no sign-up, login, or email required. You open a tool and start working immediately.

Where are my files processed?

Entirely inside your own browser. Files are read from your device into local memory, processed on your hardware, and saved back to you — they are never uploaded to a server.

Can I use PDFNEO offline?

Yes. Once a tool page has loaded, you can disconnect from the internet and the tools keep working, because all processing happens locally.

What technology powers the tools?

PDFNEO is a static site built with Astro. The tools are small React islands that run open-source engines like pdf-lib, pdf.js, and Ghostscript (compiled to WebAssembly) inside background Web Workers.
