How does PDFLince work without uploading my documents to servers?

PDFLince runs entirely in your browser with an on-device processing engine. No file is uploaded to our servers, which guarantees total privacy and fast processing.

Is PDFLince safe for confidential documents?

Absolutely. Everything stays on your device, so your PDFs never leave your control — not even we can access their contents.

Is there a limit to the size or number of PDFs I can process?

The main limit is your device memory. In most cases PDFLince handles files up to roughly 50MB each, though it can vary depending on your hardware and browser.

Does PDFLince work on mobile devices?

Yes. PDFLince is optimised for desktops, tablets, and phones. The interface adapts to any screen size.

Does PDFLince help me comply with data protection rules?

Because processing happens locally, no personal data leaves your organisation. That makes it easier to comply with GDPR, HIPAA, LGPD, or any internal privacy policy.

Can I use PDFLince for official forms or invoices?

Yes. It’s ideal for optimising invoices, contracts, and public administration paperwork while keeping the original quality.

Will compression affect the legal validity of my documents?

The PDFLince compressor preserves document integrity. Even so, we recommend confirming that the resulting file meets the specific requirements of the receiving entity whenever the stakes are high.

What technology powers PDFLince?

PDFLince uses a lightweight JavaScript engine to manipulate PDFs natively in the browser without relying on native extensions. That keeps the bundle lighter and maintenance simpler.

Do interactive elements get lost when I compress a PDF?

In most cases PDFLince keeps links, forms, and bookmarks. With very aggressive compression some advanced features may be altered, so we recommend double-checking.

Which browsers are compatible with PDFLince?

PDFLince works with modern browsers such as Chrome, Firefox, Safari, Edge, and Opera. All you need is an up-to-date browser with ES2020 support — no extra runtimes required.

Can I convert a PDF to other formats?

Right now you can convert PDFs to images (PNG or JPEG) and build PDFs from JPG, PNG, or WEBP without uploading files. For other niche formats, keep using a dedicated converter while we continue expanding the toolkit.
