Built for Speed and Privacy

Your Files Stay Yours

We never upload your documents to a server. All the processing code runs directly on your computer, so your sensitive data never leaves your sight.

No Waiting Around

Because everything happens locally, you don't have to wait for large files to upload or download. The tools use your device's power to finish the job in seconds.

Use It Anywhere

You don't need to install any apps or create an account. Whether you're on a laptop, tablet, or phone, just open the site and get to work.

Frequently Asked Questions

Is CarePDF really free?
Yes, it's completely free. We don't hide features behind a paywall, ask for your credit card, or force you to make an account. You can use all the tools as much as you need.
Are my files safe?
Yes, because they never actually leave your device. The website loads the code it needs, and then your browser does all the work locally. We have no way of seeing your files.
What kind of tools do you have?
We have over 30 tools to help you manage PDFs. You can merge them, split them, make the file size smaller, convert them to Word or images, and even add passwords or signatures.
Do I need to download an app?
Nope. Everything runs right in your web browser. Just go to the website and you're ready to go.
Is there a limit on how big my file can be?
Because the site relies on your computer's memory instead of a server, the limit depends on your device. Most modern computers and phones can handle files up to 100MB pretty easily.
