Non-editable PDFs are PDF documents that have been locked and secured to prevent editing.
This can be useful if sending reports, important documents, final drafts, or anything that you wouldn't want others to make changes to.
Whether it be academic or business reasons, non-editable PDFs are a great way to share documents with others, while resting assured that the PDF won't be changed.
But how do you make a regular PDF non-editable? We’ll show you the best methods below, so keep reading!
There are two main ways to make a PDF a non-editable:
Quick Tips:
The most common way to make PDF non-editable is to secure the PDF with a password that changes the PDF to “read-only”.
You can lock a PDF by setting a password that is secured with encryption.
This means that others will be able to open and view your PDF document, but won't be able to make edits to it.
The easiest way to save a PDF as read-only is by using a PDF editor that is capable of securing and locking documents.

1. Open the PDF in PDF Pro.
2. Press the Secure tab.
3. Press the Password button.
4. In the dialog box, under the Permission section, Click the checkbox that says: “Require a password to change security settings and access specific functions" and select None from the Changes allowed dropdown menu.
5. Set and confirm your password, then press Finish.
Especially for fillable PDF forms, before saving or sending it to others, you can flatten the PDF to paint the contents permanently onto the PDF document.
This will remove the interactive functionality of the PDF form, but can prevent unwanted edits to the fillable forms.
Note: Flattening fields cannot be undone. So if you plan on needing to work with these form fields again, be sure to keep the original document, and save the flattened PDF as a new document (Click: File > Save As)
1. Open the PDF in PDF Pro.
2. Press the Create tab.
3. Press the Flatten file button.
4. Press Create.
1. Open the PDF in PDF Pro.
2. Press the Create tab.
3. Press the Flatten file button.

If you’re just looking to flatten your PDF document, and don’t need to add extra security permissions, such as a password, you can do that using your built-in browser on your computer.
Popular browsers are Google Chrome and Microsoft Edge, but the process will be similar for any browser that can view and print PDFs.
1. Open the PDF that you want to flatten in the browser of your choice.
2. Press Print (or [ctrl] + [p] on your keyboard).
3. Set your Printer to Microsoft Print to PDF, then press Print.
4. Choose a destination & name for your flattened PDF, then press Save. (Tip: if you’ll need the fillable fields later, be sure to keep the original file).
Another free way to flatten a PDF document is by turning the document into an image; the easiest way to do this is by taking a screenshot of it. This works best if the document is a single page.
1. Open the PDF document.
2. Zoom out until you can see the whole document on your screen.
3. Press [Windows key] + [shift] + [s] on your keyboard (or type Snipping Tool into the Windows search bar on the bottom left of your screen). Your screen will appear to be grayed out.
4. Use your mouse to click-and-drag until your entire PDF is within the non-grayed out area.
5. Click the PDF thumbnail that appears on the bottom right of your screen.
6. In the Snipping Tool dialog box, press Save.
7. Choose a destination & name for your new image of your PDF, then press Save.
