Locdone is a free PDF toolkit that runs in your browser, not ours.
Merge, compress, redact, split, Bates-number — all processed locally on your device. No uploads. No account. No one else sees your files.
Local processing. Done instantly. That’s the name. That’s the architecture.
Sharing documents with AI? Redact first.
Millions of people now upload medical records, financial statements, and legal documents to ChatGPT, Claude, and other AI tools for analysis. Before you do — redact what doesn’t need to be there. SSNs, account numbers, diagnoses, names. Gone from the file before it leaves your hands. Locally. Free.
Client files are privileged. Uploading them to iLovePDF, Smallpdf, or any cloud PDF tool is a professional ethics risk. Locdone processes entirely in your browser -- nothing ever leaves your machine.
PHI belongs in your hands. Most online PDF tools store files on their servers, which means a BAA, a data processing agreement, or a breach notice waiting to happen. Locdone doesn't touch your files.
Most free PDF tools monetize by processing your files on their servers. Locdone runs on open-source libraries in your browser tab. You can verify it -- open DevTools, watch the Network tab stay empty.
Built for professionals who legally can’t click “upload.”
HIPAA, attorney-client privilege, court protective orders — some documents cannot touch a third-party server. These tools don’t.
The processing code runs inside your browser tab -- not on a server you're trusting blindly. Close your WiFi and it still works.
No upload progress bar. No 'your file is being processed' spinner. Drop a file, get a file.
No watermarks, no daily limits, no signup. There's no server to pay for, so there's nothing to charge you for.
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.
Read the privacy architectureFrequently asked
Common questions, honest answers.
Why should I trust that nothing is uploaded?
You shouldn't have to take our word for it. Press F12, open the Network tab, then drop a file and process it. You'll see zero outbound requests while your PDF is being handled. The processing code is open source and runs entirely in your browser using pdf-lib and pdf.js.
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.
How is Locdone different from iLovePDF or Smallpdf?
Those tools upload your file to their servers, process it there, then send it back. That model works, but it means your file touched a third-party computer. Locdone uses your browser as the processing engine -- the file never leaves your tab.
Is it safe to use before uploading documents to AI tools like ChatGPT?
Yes -- that's one of the most common reasons people use Locdone. Redact the sensitive parts (SSN, account numbers, names, diagnoses) locally first, then share the cleaned version with an AI. Since nothing is uploaded to Locdone's servers, your original document stays private throughout.
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.
Does it work on mobile?
Yes. Locdone works in any modern browser on desktop, iOS, and Android.
