Frequently asked questions
Everything you need to know about ZimaPDF and how it secures your files.
Are my files really secure and private?
Yes. Unlike almost every other free PDF tool on the internet, ZimaPDF processes your documents locally in your web browser using advanced client-side technology. Your files literally never leave your computer and are never uploaded to our servers.
Is there a file size limit?
No. Because your files are not being uploaded to a remote server, we do not have an arbitrary file size limit. You are only limited by the memory (RAM) available on your own device.
Is ZimaPDF completely free to use?
Yes, 100% free with no hidden paywalls. Traditional PDF editors have to pay massive server bills to process thousands of massive files every minute, which is why they eventually charge you a monthly subscription. Because ZimaPDF runs locally on your own computer's hardware, our running costs are practically zero, and we pass those savings directly to you.
Do I need to install any software?
No installation is required! ZimaPDF works instantly in any modern web browser including Google Chrome, Apple Safari, Mozilla Firefox, and Microsoft Edge.
Does this work on Mac, Windows, and Mobile?
Yes! Because ZimaPDF is completely browser-based, it works flawlessly across Mac, Windows, Linux, Android, and iOS devices.
