The Workshop

Every tool you need. None you don't.

Thirteen focused instruments, each crafted to do one job exceptionally well. All processing happens locally in your browser — your files never touch a server.

Why PDFLabs

Built different. Built yours.

Most PDF tools upload your files to a server you've never heard of. PDFLabs doesn't.

Private by design

Every byte stays on your device. There's no server, no upload queue, no tracking pixel watching what you do.

Instant

No upload time. No queue position. Processing starts the moment you drop a file — as fast as your CPU allows.

No limits, ever

No page counts. No file size caps. No watermarks on output. No signup. Use it on 5 files or 5,000.

FAQ

Questions, answered.

Are my files really not uploaded anywhere?

Correct. PDFLabs runs entirely in your browser using JavaScript. When you select a file, it's read into memory locally and processed by your device's CPU. We have no server — there's nowhere for the file to go even if we wanted to.

Is there a file size or page limit?

No artificial limits. The only constraints are your device's RAM and processing power. Very large PDFs (100MB+) may take longer on slower devices but will work.

What about encrypted PDFs?

Most tools can open password-protected PDFs if you provide the password. For security reasons, encryption cannot be added in-browser — that requires server-side processing.

Does it work offline?

Once the page loads, yes. All libraries are loaded upfront. You can disconnect from the internet and keep using every tool.

Is it really free?

Yes. No tiers, no premium, no "pro" version. Use it as much as you want. If it saves you time, consider sending some USDT to support the project!
