How to protect a PDF file for free

There are three simple steps that you need to follow in order to protect a PDF document. First of all, you need to upload the file that you want to edit. Then, select the option to add a password to your PDF file and start typing it. Remember to click the save button so your changes will be applied to the PDF, and then feel free to download the new, protected PDF.

Lock a PDF file so it won't be editable - PDF Protecting

If you want to restrict people's access to your document, then a PDF protection is what you're looking for. Moreover, we believe that we have the solution for you, as we've built this online and free PDF protector that is going to let you set a password for your document. This way, nobody else besides you and whoever else has the password can't access the document, and you get to control who has access to your PDF. Drag and drop your document, add a password and save.

Locked PDFs

Our online PDF protecting software does a simple thing that is going to give you full control of who has access to PDF documents: adding a password that you get to choose. Take care of your content!

100% Control

You're the one in charge of who gets to access a PDF document. Keep the password just for yourself, share it with friends of work colleagues, or do whatever you need with the PDF. We never look at your files either.

Unlimited files

With SignHouse's software that helps you protect PDF files, you get to chose how many documents to lock. We're not setting a daily limit of password-protecting PDF files. Hence, you get unlimited PDF protecting.

Oh, and it's free

Besides the fact that you get to protect as many PDF documents as you need, one huge advantage is that our tool is free of charge. That's right - guaranteed free PDF password-protecting without any gimmicks!

Why should you protect a PDF with us?

At SignHouse, we're doing our best to expand the possibilities to customise a PDF as much as you want. The two greatest advantages of our tool are that you don't have to pay to use it, and that you can protect PDF documents on any device. We don't want to say that SignHouse is what you need, and instead, we want to show you the benefits and let you decide.

Use any device

You can use our free PDF protection software on all of your devices. Whether you like to use your phone or tablet more than your computer (or the other way around), SignHouse is guaranteed to work properly.

Secure PDFs

This goes beyond protecting your PDF documents with passwords, because locking a PDF is 100% safe with SignHouse since we never look at your PDF files, and we never share them without your will.

Drag & Drop

It's not that hard to password-protect a PDF file. All you have to do is just drag and drop the document that you want to protect with a password, fill in your password and then save the new file. That's it!

What they say about us

No-brainer pricing for a small business - or even big business, I reckon : - )

Tried the product. Worked like a charm. Never had any problem + the clean UI got us. Wish there would be more features, but I believe in the team behind.
Harsh G.
Founder, CEO
SignHouse has been nothing short of convenient, efficient and fast. Oh and top notch customer support too...

Couldn't ask for more!
Julie M.
Executive Administrative Assistant
SignHouse has made a big difference in the workflow of my business. Sure there are other, more mature e-signing platforms out there, but they are all convoluted and too focused on big, enterprise companies. It feels like SignHouse is on our side.
Michael B.
Photography Consultant
Getting documents to parents is significantly simpler now. However, even more importantly, parents aren't getting lost in the signing process anymore. 👍
Sandy T
SignHouse was AMAZING for what we needed. "Do one thing and do it well" - they've nailed that, as everyone is very happy with the product here.

Looking forward to seeing how the product develops, as the team is super ambitious.
Kate Gross
Manager at
"Simpler, yet does the job better than most of the clunky eSignature software out there"
"SignHouse cut down on our signing processes by at least 50% - and we were using eSignature software before as well"
"I just never thought signing documents can ever become a pleasurable experience"

Frequently asked questions

No items found.

Are your electronic signatures legal?

Our signatures are 100% legally binding, as SignHouse is built around US and International Laws concerning digital signatures. SignHouse eSignatures are on par with paper signatures, from a legal point of view!

Signing papers digitally started being equal to physical, handwritten signatures in the U.S. eSignature Act of 2000 (U.S. Federal Act) + the Uniform Electronic Transaction Act (UETA). As a consequence, laws in other countries have followed suit. SignHouse is built around these laws.

Are you adding an actual eSignature or just an image?

All signatures are a real, eSignature that is 100% legally binding.

We save important, relevant data (that can be used legally in all types of situations, including in courts) such as identifiable details of a person, IP addresses, etc, just so our electronic signatures can be as valid as digital signatures can get.

What about privacy and security?

SignHouse's signatures are secure for all kinds of businesses and companies. All our signatures happen on a secure, SSL-connected domain. Documents are not made public and unique keys are generated through SignHouse so that privacy and security are at the foundation of the documents on our platform.

How do my signees get to sign with SignHouse?

We've streamlined the signing process so that your signees can sign your documents with no hurdles at all — and with the smallest amount of steps required. It can take as little as 30 seconds!
