Terms of Service

Last updated: May 30, 2026

Welcome to OncePDF! We're glad you're here. This page basically outlines the "ground rules" for using our website. By hanging out here and using our tools, we're assuming you're okay with everything written below. If you're not, that's okay too—but you probably shouldn't use the site.

1. The Content & IP

We've put a lot of work into the code and the design of OncePDF. Unless it's a document you've uploaded (which you obviously still own), all the stuff you see here belongs to OncePDF or our partners. We're happy to let you use the site for its intended purpose, but please don't try to copy or resell any part of it.

2. What you shouldn't do

We want to keep this place helpful for everyone, so there are a few things we have to be strict about. Please don't:

  • Try to scrape the site or republish our content elsewhere.
  • Attempt to sell or "commercialize" any part of OncePDF.
  • Use the site in a way that slows it down for everyone else.
  • Do anything illegal or harmful using our tools. We're here to help, not to facilitate mischief.

3. No Warranties (The "As Is" Part)

We do our absolute best to make sure everything works perfectly, but at the end of the day, OncePDF is provided "as is." We can't promise that it will be error-free 100% of the time. Using the site is at your own risk, and nothing here should be taken as official professional advice.

4. Limitation of Liability

Because we're providing this service for free (and mostly in your browser), we can't be held responsible for any issues that might arise from using the site. Whether it's a technical glitch or a misunderstanding of how a tool works, OncePDF and its creators won't be liable for any damages or losses.

5. Indemnification

If you break these rules and it causes a problem for us, you agree to take responsibility and cover any costs or issues that come up because of that breach.

6. Changing the Rules

Sometimes the internet changes, and we might need to update these terms. We can revise them whenever we need to, so it's a good idea to check back every now and then if you're a regular user.

7. Governing Law

Any disputes would be handled according to the laws of the region where OncePDF operates. We hope it never comes to that, though—we'd much rather just help you with your PDFs!

8. Questions?

If any of this sounds confusing or you just want to know more, drop us a line at legal@oncepdf.com. We're here to help keep things clear.

Our Commitment to Your Digital Safety

Let's take a quick pause from all the formal legal jargon and talk honestly about what really matters here: your safety and your trust. Reading through terms of service pages can usually feel like wading through mud, right? We completely understand that. But the real highlight of our philosophy is transparency. We want you to fully understand exactly how we operate and why we made the specific architectural choices we did when building this platform.

When you use our tools to watermark a PDF or merge important files, you are often dealing with highly sensitive, confidential information. Traditional online document editors typically force you to upload these private files to their remote servers. Just looking at it, that standard industry practice always felt incredibly risky and entirely unnecessary to us. That is exactly why we decided to completely flip the script and build something fundamentally different.

The Power of Zero Server Uploads

We firmly believe that what happens on your device should always stay strictly on your device. By harnessing the incredible, cutting-edge power of modern WebAssembly and advanced HTML5 technologies, we've successfully engineered a platform that processes all of your documents entirely locally within your own web browser. Zero server uploads. None at all. It's the kind of rock-solid security feature that instantly gives you total peace of mind.

Think about the sheer implications of this localized approach. Because your files literally never leave your computer, there is absolutely zero risk of them being intercepted during network transit, stored on some forgotten backup server, or accidentally exposed in a catastrophic data breach. You've got this amazing, powerful computer right in front of you, and we simply let it do all the heavy lifting securely. It's that simple, and honestly, it's how all web software should eventually be built.

Speed Meets Uncompromising Privacy

Of course, avoiding server uploads doesn't just dramatically improve your security; it also results in blazing, lightning-fast performance. Have you ever waited painfully long minutes for a massive document to upload just so you could quickly protect a PDF with a password? It's incredibly frustrating and completely wastes your valuable time. By processing everything client-side, we completely eliminate those annoying upload and download wait times.

The moment you drag and drop a file onto our platform, the processing begins almost instantaneously. You get your finished, perfectly formatted results exactly when you actually need them. We are incredibly passionate about respecting both your data privacy and your busy schedule. We've purposefully optimized every single line of our underlying code to ensure that our tools are not only the safest option available on the internet but also definitively the fastest.

A Fair and Transparent Relationship

We wrote these terms of service not to trick you or trap you in convoluted legal loopholes, but to clearly establish a fair, mutually respectful relationship. We are providing you with powerful, deeply secure tools entirely for free, and in return, we simply ask that you use them responsibly and respectfully. We don't track the contents of your documents, we don't harvest your personal data to sell to advertisers, and we certainly don't play hidden games with your privacy.

We are constantly working hard behind the scenes to improve our platform, adding new features and refining our local-processing technology to be even better. We genuinely appreciate you taking the time to use our services and for trusting us with your document workflow. If you ever have any questions about how we fiercely protect your data, please don't ever hesitate to reach out to our support team. We are always here to help you get the most out of your experience!
