Frequently asked questions
What encryption standard is used?
The PDF is encrypted with a password using standard PDF encryption. Only someone who enters the correct password can open or view the document.
Do I need to install anything to use these PDF tools?
No installation required. Every PDF tool is browser-native and runs on modern browsers (Chrome, Edge, Firefox, Safari) without plugins, extensions, or desktop apps.
Does this upload my file?
No. Your file stays on your device the whole time. LoveMyFile runs entirely in your browser, so nothing is uploaded to a server, queued in the cloud, or copied off your computer.
Is this free?
Yes. Every tool is free and unlimited — no account, no paywall, and no daily caps. Because the work happens locally in your browser, there are no per-file or per-page charges.
Does it work offline?
Yes. Once the page has loaded, the tools run entirely in your browser, so you can disconnect from the internet and keep working. AI-powered tools download a small model on first use and then also run offline.
