It's often helpful to scan documents, but they can also be hard to work with because they are made up of pictures. But anyone can learn how to edit a scanned PDF document if they get some help.

We'll give you step-by-step instructions, best practices, and helpful tips to make sure you can correctly change and convert your files.

What is a Scanned Document?

A scanned document is a digital replica of a physical paper, which is usually a paper that has been placed in a scanner to create an electronic version. It is commonly stored as a PDF document, JPG image, or TIFF file. Learn more information about formats below in this article.

Such content has many uses, such as keeping digital copies of important papers and making it easier to share them with others.

It also lets you perform any changes, like fixing typos or adjusting the layout. This method allows for storing documents, so they are accurate, efficient, and safe.

Types of Scanned Documents

As we rely more and more on e-files, it's important to understand the differences between their types. Once you scan a paper, the result can be stored in a variety of formats.

These are determined by the type of content. Common options include PDF, JPG, and TIFF. Each has its own benefits:

  • PDF format is popular for security features and compatibility with many devices.
  • JPG is great for sharing photographs and other images.
  • While TIFF is great for preserving quality with a large size.

Knowing the contrast between each format can help you choose the best options for editing PDF files.

Why can't I edit a scanned PDF?

It can be discouraging when you have a paper that needs amending, but it's already been scanned. You can't just type in changes like you would with any other. So why can't you edit scan documents?

The reason is that when you scan something, it's converted into an image. This means that any text within the pages is no longer accessible, but rather as part of the picture. You can't select and change it like normal text.

However, all hope is not lost! You can utilize OCR to convert it into an editable PDF. This service recognizes text and turns it into a digital file that is searchable.

Once the conversion is complete, you can open the new version in a PDF editor to modify it. You can add, remove text, or adjust formatting as needed.
