FAQs

General Questions

Is Space PDF really free to use?

Yes, absolutely. All our tools, from editing to merging, are 100% free. There are no hidden costs, no subscription fees, and no need to create an account.

Do I need to install any software?

No. Space PDF is a fully online tool. You don’t need to download or install anything on your computer. Just open our website in any modern browser like Chrome, Firefox, or Safari and start working.

Can I use these tools on my mobile phone or tablet?

Yes. Our website and all our tools are designed to be fully responsive, so you can easily edit, merge, or sign PDFs on most modern smartphones and tablets without any issues.

Do I need to sign up to use the tools?

No, you don’t need to create an account. You can start using our tools right away. We believe in making things quick and easy for you.

Security & Privacy

Is it safe to use? What happens to my files?

Your privacy is our number one rule. Your files are never uploaded to our servers. All processing (like editing, merging, or signing etc) happens directly in your web browser. This means your documents stay on your computer and are never seen by us.

How long are my files kept?

They aren’t kept at all! Since we never upload your files, we never have them in the first place. When you close the webpage, your session is gone, and so is any temporary data from your work.

Tool-Specific Questions

What can I do with all these tools?

You can perform all the most common PDF tasks! You can edit text, merge multiple PDFs into one, remove or reorder pages, rotate pages, e-sign documents, add page numbers, convert images to PDF, and even crop your PDFs.

What is the "PDF Corruptor" tool for?

The PDF Corruptor is a unique “lifesaver” tool. It’s designed for students or professionals who need to submit a file to meet a deadline but require more time to finish their work. It creates a file that looks like a valid PDF but won’t open, giving you a valid reason to ask for an extension.

What file types can I convert?

Our converter tools are designed to work with common image formats. You can easily convert files like JPG, PNG, and WEBP into a PDF. You can also convert a PDF back into images.

Are the digital signatures legally binding?

Digital signatures created with tools like ours are widely accepted and legally recognized in many countries, including the United States (under the ESIGN Act). However, for very important or specific legal contracts, it’s always a good idea to check your local laws or consult with a legal professional.

Technical & Troubleshooting

Are there any limits on file size or usage?

Since all processing is done in your browser for security, very large or complex files (e.g., over 50MB or with hundreds of pages) might be slow or cause your browser to crash. For most everyday PDF tasks, our tools work perfectly. There are no limits on how many times you can use our tools.

Which web browser should I use?

For the best experience, we recommend using the latest version of modern browsers like Google Chrome, Mozilla Firefox, Microsoft Edge, or Safari.

My file is not working. What should I do?

First, please make sure your file is not password-protected, as we cannot process encrypted files for security reasons. Also, check if the file is corrupted. If it’s a very large file, it might take longer to process. If you still have trouble, try refreshing the page and starting over.

I have a question that isn't listed here. How can I get help?

We’re always here to help! If you have any other questions, suggestions for new tools, or if you’ve found a bug, please don’t hesitate to email us directly at support@spacepdf.com. We read every message and will do our best to get back to you as soon as possible.
