Close your WiFi. Drop a file. Watch DevTools (F12) Network tab stay empty while processing — that's the guarantee.
No upload queue, no waiting room. Drop a file, get a file.
No watermarks, no signup, no daily limits. Every tool, every feature.
Don't take our word for it.
Press F12 to open devtools, switch to the Network tab, then drop any file into any Locdone tool. Watch it stay empty while your PDF is processed — that's the whole trust model.

Common questions, honest answers.
Is Locdone really free?
Yes — every tool is free, with no daily limits, no watermarks, and no signup. Locdone runs in your browser, so there are no servers to pay for.
Are my PDFs uploaded to a server?
No. All processing happens locally in your browser using open-source libraries (pdf-lib and pdf.js). You can verify this yourself — open your browser's Network tab and you'll see zero requests while a file is being processed.
Do I need to create an account?
No account, no email, no sign-up. Open the site, drop a file, download the result.
What file types are supported?
PDF files for merge, compress, organize, and redact; JPG and PNG images for conversion to PDF. Most browsers handle files up to around 100 MB smoothly.
How is Locdone different from other online PDF tools?
Most "online PDF" tools upload your file to a server, process it there, then send it back. Locdone never uploads anything — your file stays in your browser tab from start to finish. That means it's private by design, works offline once loaded, and stays fast even for sensitive documents.
Does it work on mobile?
Yes. Locdone works in any modern browser on desktop, iOS, and Android. It's also installable as a PWA.
