Many of us often find ourselves needing to make small edits to our PDFs, but it always seems harder than it should be. Generally, PDFs by nature are not meant to be modified or edited by a source other than the original creator. Due to this reason, editing a PDF document is not always a straightforward process. In this article, we are going to teach you how to write, edit, modify or add onto PDFs with the easiest, most practical, and the most reliable techniques. In fact, you can do more than just write on a PDF document. Images, dates, annotations can be added and even scanned documents can be edited with the use of PDF editing tools.
How to add text to a PDF
PDF documents can be created and opened on almost any standard device these days. To add text on a pre-existing PDF document, however, you’ll have to rely either on software with PDF editing or importing capabilities. Here are your major options:
How to add text to a PDF with Microsoft Word

STEP 2 Add the necessary changes to the document.
STEP 3 Go to File then click on Save As.
STEP 4 Find Save as type dropdown options and select PDF.
STEP 5 Save the document.
Your document is once again saved as a PDF with all changes. This method works reliably with text-only PDF files but may struggle with files that have multiple media types, fields, and options.

How to edit a scanned document
A scan is a digital snapshot of a document. Scanned documents can be saved as a PDF as well and then edited using any of the options mentioned above. A scanned document by default is saved as an image. We recommend using Microsoft Word to convert a scanned document into a PDF. Here’s how.
- Make sure that the scanned document is in a common file format such as ‘.jpg’ or ‘.png’.
- Open Microsoft Word and Copy/Paste or Open the scanned image into the Word Document.
- Adjust the size of the image and margins so that it fits into the page.
- When the image is properly adjusted, go to Save As and select Save As Type dropdown.
- Select PDF format and Save the document.
- Your saved document is now a PDF file and can be edited with Adobe Acrobat or online PDF editors such as Docdown.

How to add image to PDF
As a standardized document format, PDFs support both text and images. For this reason, application forms and contracts are created and transacted in PDF format. It protects the integrity of documents, their formatting, and style. If you’re looking to add an image to a preexisting PDF document, there are a variety of ways to do so. Unfortunately, we don’t recommend Microsoft Word for this purpose. Word cannot reliably distinguish between the text fields and image fields of a document and can often overwrite settings. Adding an image can be a hassle due to this reason. Here are the easiest and most reliable ways to add images to a PDF file.

Why are PDFs hard to edit
Being a highly complex and cross-platform format, PDF files maintain the original formatting of a document. For this reason, they are primarily utilized for viewing and sharing, rather than editing or creating. Almost all industries rely on PDF documents for information dissemination and to share resources. Application forms, business contracts, rules and guidelines, organizational handbooks, and countless other public and private use documents are saved as PDFs. The PDF format was first developed by Adobe in 1993 and has since been adopted widely. The format is ISO certified.
Editing a PDF document is possible, as our tutorial above shows. But it’s not exactly a straightforward process. Opening PDF documents in text editors can overwrite PDF settings and modify their original formatting. This is a deliberate feature to discourage unwanted edits and to remove oversight.
