Some of the most prominent ways to remove signatures from PDFs include conversion to editable format and flattening and redacting them.

To remove a signature from PDFs, you can undo changes on a freshly signed document, edit out signatures, convert them to editable format, delete them, and flatten and redact your document.

You may need to delete signatures from PDFs after accidentally signing them, or you may want to 

by replacing one signature with another. However, PDF signature removal may not always be possible due to high-security levels.

Read on to discover more about which signatures are removable, how to remove them, and how to protect your documents from unwanted signature removal.

 depends on their type. Signatures are usually classified according to how they are produced and their security levels.

Digital signatures are electronic data transferred to an online document that proves someone’s intention to sign it. There are three types of digital signatures—

Their security levels differ; simple signatures have the lowest, advanced ones boast high, and qualified signatures have the highest security levels. In general, you can remove an e-signature from your document right after signing it, as the signing process is not complete, and the platform allows you to revoke your action. Alternatively, you can delete simple signatures from documents someone else has signed using editing tools, such as PDF.net.

In contrast, if someone sends a signed document, especially one with an advanced or qualified signature, it will be impossible to remove PDF digital signatures 

. You can create electronic signatures by typing your name and positioning it in a document. You can also use a signature image and insert it into a PDF document.

Unlike most digital signatures, you can remove electronic signatures from PDFs by editing them out. Specifically, our

 include printed PDF copies that people manually sign. Editing a hard copy online is impossible, and modifying it physically could leave marks (e.g., scribbles) and lower its credibility.

Alternatively, you can edit hand-drawn signatures by scanning a hard PDF copy. After you do this, you must use 

 to mark the signature and make it invisible by matching its color with the background.

It is important to note that erasing signatures in PDFs can invalidate documents. Most tools can detect signature removal since signatures use 

 and revoke document trust, which means they can restrict their services for the document.

Also, once documents that must be signed (e.g., legal real estate documents) lose the signature, they also

4 Methods for Removing a Signature From a PDF

There are several ways to remove signatures from PDFs, allowing you to revise and revamp your documents.

With that in mind, let’s examine the top four methods to extract a signature from a PDF document:

#1. Remove the Signature Using the Undo Option

You can undo a PDF signature using the same option on an online PDF editor. This process is simple—click the 

This will automatically clear the signature from your document. If you have multiple signatures on your file, you can repeatedly click the 

icon until all of them are removed. Once you delete the signature, you can continue editing your file and download it afterward.

#2. Delete a Signature From an Editable PDF

You can edit a signed PDF and remove a signature if it is not encrypted. For instance, if a signature is typed and placed into a document as a fillable form, you can use the selection tool to select a signature and remove it by clicking on the 

 icon in the upper-right corner of the toolbar.

You should repeat this process for every signature in the document, after which you can download your PDF file. In addition to this removal method, you can delete signatures on mobile devices, as our platform also allows 

#3. Convert the PDF to an Editable Format

To edit out signatures from non-editable PDFs, you must enable the editing option first. If you want to make an image-based PDF editable, you can OCR it to detect and extract its content. Then, you can find, select, and remove signatures from it.

Additionally, you can convert PDFs to other editable formats. For instance, 

 will make all its contents editable (including fillable text forms with signatures). Afterward, you can select the signature and use the 

 on your keyboard, or right-click it and click the 

#4. Flatten the PDF and Use a Redaction Tool

Another way to unlock signed PDFs is to make layers uniform by flattening them. PDF.net allows you to flatten the entire document or only fillable text forms, which will also flatten PDF signatures.

You can flatten fillable text forms to remove typed-in signatures. Moreover, to erase other types of removable electronic signatures, you must flatten the entire document. To do so, visit our website, upload your document, select the flattening tool, and choose between the 

complete or fillable form flattening option

Following this, you should use the redaction tool to select the document parts with signatures and remove them by activating the reduction option. This will automatically

 match the signature color to the background color

How to Prevent Removal of Signatures From PDF Documents

To prevent the removal of signatures from PDF documents, you should use highly secure digital signatures and protect your files with security tools.

Let’s examine these methods in greater detail:

. Digital signatures are non-removable due to high encryption. Therefore, look for a platform that offers digital signatures instead of electronic ones. These signatures also use 

, which enables only the sender and receiver to see the signed document.

. You can lock your PDFs with a password and make them accessible only to specific users. Plus, you can 

 in different ways—disable printing, copying, and adding comments or make them non-editable and read-only. These security measures add more protection to your PDF documents and prevent the removal of signatures.

Using PDF.net for Flawless Signature Removal and Protection

high encryption, preventing the removal process

. Using cheap tools instead of reliable ones may also prevent signature removal.

#4. Will removing a signature make a document invalid?

 if it requires signing to be valid (e.g., business contracts). Also, some software may detect the previous signature’s existence and restrict the availability of its options, rendering it untrustworthy.

#5. Can I remove a signature from a scanned PDF?

You can convert a PDF font to another one and change color, style, and size, but you may not be able to modify embedded PDF fonts.

First, you can change font type (e.g., switch from 

 to a handwritten font). Font type directly impacts the document’s readability, as different letter shapes can be easier or harder to understand.

In addition to using different font types, you can change the PDF font size. This can make the text 

, as you can enlarge letters that are too small. Also, resizing letters is a much easier way to improve a document’s readability instead of using complex methods, such as 

 or kerning, to adjust PDF font settings.

If you want to standardize your document, you can use the default black font color or decorate it by switching to warm colors. Similarly, you can emphasize important elements within the text by changing the font style (e.g., use bold and italics).

However, it is important to note that some documents 

. For instance, you may use a file with embedded fonts, which are not installed on your PDF reader, resulting in restricted editing (e.g., only being able to change font color).

When changing fonts in PDFs, it is essential to use readable fonts, be moderate while using decorative ones, and ensure that all readers can open such files.

Let’s examine these tips in more detail:

Choosing readable fonts is one of the most important things for having a

Moreover, some fonts may be so distorted that it is almost impossible to read them. For this reason, we recommend using either 

. You can test the readability by using a PDF with unfamiliar content, changing the text font without previously looking at the content, and trying to read it for the first time.

Decorative fonts can make your text look more interesting, sophisticated, and polished. However, overusing them can also make your documents look more 

informal and casual and, therefore, less professional

Even if your file is not official (e.g., a government form), overusing decorative fonts can also

. The reason for this is that letters can take on weird shapes because of all the curves and decorative elements.

Some readers may be unable to open or render your new font correctly after changing it. To prevent this, you can flatten your PDF file. This will combine all different layers into one, ensuring that any reader can 

open and display the PDF text in its original form

, regardless of the manufacturer or operating system.

This will also facilitate the sharing process, as merging layers can shrink PDFs. Still, as flattening is one of the ways to make your PDFs non-editable, we recommend making a copy of your original file before doing so.

Troubleshooting Common Issues When Changing Fonts in PDFs

As PDFs are not as editable as Word or similar text documents, font editing may also be unavailable for some documents. For instance, some PDF readers may only allow you to change font size and color, but not type. A typical cause of this is 

, which are not installed on your reader.

Another reason why you may not be able to edit text or change PDF fonts is font restrictions, which are common for certain fonts (e.g., Google fonts). Finally, your PDF may be a scanned image, meaning that you cannot select text or change the font.

, which creates more editing opportunities and makes it easier for you to change the font. Once you are done, you can convert your document back from 

. File recreation is a conversion alternative. All you should do is copy the contents from your PDF to a blank Word or similar text file, change fonts, and save it as a PDF (this only works for editable documents).

Use an online reader instead of an offline one

. Offline readers typically require additional installation to render specific fonts. In contrast, online readers such as PDF.net will automatically recognize 

For non-selectable, image-based PDFs, you can use our OCR tool to make them 

, enabling you to change PDF fonts afterward.
