Your files are your business

Many “free” PDF tools upload your documents to a website to work on them. HearthPDF does everything on your own computer.

Stays on your PCYour PDFs are opened and saved on your computer. They are never uploaded anywhere.
Works offlineThe app never connects to the internet. Unplug the network and it works the same.
No trackingNo account, no sign-up, no analytics, no adverts in the app. We don’t know who you are.
Free foreverNo trial, no watermark on your files, no “pro” version. If it helps you, you can buy us a coffee.

Questions

Is it really free?

Yes. There is no trial, no time limit, no watermark added to your files and no paid upgrade. You can use it at home and at work. Donations are entirely optional.

Does it upload my files?

No. HearthPDF has no online features at all. It opens and saves files on your computer only. The only time anything opens on the internet is when you choose a link in the Help menu (this website or the user guide), and that opens in your own browser.

What does it store on my PC?

Only its own settings: your recent files list (which you can switch off) and your name for comments. Help ▸ Privacy and your data shows exactly what is stored and deletes it in one click. See the privacy page.

Windows says “Windows protected your PC”. Is it safe?

That message appears for new apps that Windows hasn’t seen many times yet. Click More info, then Run anyway. You can check that your download is genuine on the download page.

Can I fill in forms?

Yes: use Add text to type anywhere on the page, which works on any form, including scanned ones.

Does it work on Mac or Linux?

Not at the moment. HearthPDF runs on Windows 10 and Windows 11 (64-bit).

Something doesn’t work. How do I report it?
