How to flatten a PDF file

If you want to flatten a PDF file, you should follow these three simple steps: first, upload the PDF file that you want to flatten, and then select the flatten method. You can either leave the settings as they are, or you can choose to customise the way of flattening that file. Up next, you have to apply the changes and wait about 30 seconds. Then, you can download the freshly flattened PDF file so you can scan & print it. To recap, here's what you have to do:

2. Adjust settings & Flatten

Make the fillable forms fields of your PDF file un-fillable and apply the flattening changes.

3. Download the new file

Wait about 30 seconds for the system to do its magic and download the new PDF as an image.

What flattening a PDF really means & How to do it

Flattening a PDF is basically turning it into an image so you could print it. Into more detail, a PDF flatten software looks for transparency information within your file, and it removes that info so you can easily print the file. If you're trying to print a PDF document and you've heard someone say that you first have to flatten it, you now know 100% what that means. With SignHouse, you can easily flatten a PDF document in just a single click and a couple of seconds of your time.

How to flatten a PDF file

Easier to print

Flattening a PDF document is basically getting rid of the transparent data within that document. With less extra data such as images (e.g. PNG files in PDFs), it's easier to print PDF documents.

Unlimited files

Flatten as many PDFs as you want. At SignHouse, we're not setting a daily limit or anything like that. You have free will and control over your PDF documents, and you can flatten as many as you wish and need.

It's really fast

To flatten a PDF document, you need nothing but one single click and less than 30 seconds of your time. We do our best to save your time and to earn you more of that instead of wasting it on non-sense.

Price for this: $0

That's right! Not only that you can flatten as many PDF files as you need, but you get to do it for free. Our PFD flattening software is free, and it's going to stay like this forever. No gimmick!

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.
Steph G.
Chief Executive Officer
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
"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

Can you un-flatten a PDF?

Flattened PDFs cannot be edited, as they were meant to be like that when they were flattened.

However, one could use text recognition from that very image → then paste that into a new PDF.

One could take screenshots of the pictures found in the flat PDF → paste that into a new PDF.

When it comes to forms or checkboxes, they just have to be re-created from scratch.

While that’s not un-flattening, replicating the PDF is the closest method for you to get to the original file.

Why do I need to flatten a PDF?

In a PDF file, you might want to only want to restrict the filling of forms, copying of text/images.

When flattening everything, images, text, checkboxes, buttons, etc all get flattened (meaning: turning them into elements you can’t interact with).

That makes a PDF non-interactive for anyone that sees it — except for viewing.

What does it mean to flatten a PDF?

Flattening a PDF is the process of converting all of the PDF’s layers to one single layer, which will allow you to edit and save it in a much smaller file size.

The only implication is that this process will make text and images in the document inaccessible.

With PDF flattening, the exact way the PDF looks like will be turned into an image, so that it looks the exact same.

However, it will not be editable anymore in any way.

Same looks, no more functionality.

How can you tell if a PDF is flattened?

The short answer is this: if you try to highlight any text, forms, buttons, images and you can’t — that means the PDF is flat.

In other words, it’s been turned into an image. Or a collection of images (each page is an image).

That’s a flat PDF for you.

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!
