What You Can Edit in Adobe Acrobat and What You Cannot
Adobe Acrobat lets you edit text, images, and links directly inside a PDF without converting it back to Word or another format. You can change existing words, move text around, delete content, and add new text boxes. You can also rotate or replace images, adjust their size, and edit hyperlinks. What you cannot do is change the overall layout structure — if the original PDF was built from a scanned image rather than a document file, Acrobat will treat it as a picture and you will not be able to edit the text at all.
The editing tools in Acrobat work best on PDFs that were created from digital documents like Word files or Google Docs. If you have a scanned PDF (a photograph of a printed page), Acrobat has a separate feature called OCR (optical character recognition) that can convert the image to editable text, but this requires the paid version of Acrobat, not the free Reader.
Key Takeaways
- Open the PDF in Acrobat, click the Edit PDF tool in the right panel, and you can then click any text to change it or add new text boxes.
- To edit images, use the Edit PDF tool and click the image, then use the toolbar to resize, rotate, or replace it with a new file.
- Scanned PDFs (images of printed pages) cannot be edited as text unless you run OCR first, which is only available in paid Acrobat, not the free Reader.
- Changes you make are saved to the same PDF file unless you choose File > Save As to create a copy with a new name.
- If you need to change the document structure or add pages, you will need to use the Organize Pages or Insert Pages tools rather than the Edit PDF tool.
Opening the Edit PDF Tool
Launch Adobe Acrobat (the paid version) or Adobe Acrobat Reader (the free version) and open your PDF file. In Acrobat, look at the right side of the screen for a panel labeled Tools. Click on Edit PDF. The cursor will change to a text editing cursor, and you will see a blue outline around any text that can be edited.
In the free Reader, the Edit PDF option is not available — you can view and annotate PDFs but not change the actual content. If you only have Reader and need to edit, you will need to either upgrade to paid Acrobat or use a different tool like Microsoft Word (which can open PDFs and convert them to editable format) or a free online editor.
Editing Text in Your PDF
Once Edit PDF is active, click anywhere on the text you want to change. A text box will appear around that section. You can now select the words you want to edit by clicking and dragging, then type to replace them. To add a new line of text, click where you want it to appear and start typing — Acrobat will create a new text box for you.
The text will use the same font and size as the surrounding text by default. If you want to change the font, size, or color, select the text first, then look at the toolbar at the top of the screen. You will see options for font name, font size, and text color. Click any of these to adjust the selected text. Keep in mind that if the original PDF used a font that is not installed on your computer, Acrobat may substitute a different font, which can change how the text looks.
To delete text, select it and press Delete or Backspace. To move text, select it, cut it (Ctrl+X or Cmd+X), click where you want it to go, and paste (Ctrl+V or Cmd+V).
Editing Images in Your PDF
Click on any image in the PDF while Edit PDF is active. The image will be surrounded by a blue box with handles (small squares) at the corners and edges. You can resize the image by dragging any handle — drag a corner handle to resize while keeping the proportions the same, or drag an edge handle to stretch it in one direction.
To rotate an image, right-click on it and select Rotate. You can rotate 90 degrees clockwise or counterclockwise. To replace the image entirely, right-click and select Replace Image, then choose a new image file from your computer. The new image will take the same size and position as the old one.
If you want to delete an image, click it and press Delete. This removes the image but leaves the space it occupied — the text around it will not flow up to fill the gap.
Adding New Text Boxes and Shapes
To add text in a location where there is no existing text box, click the Add Text tool in the toolbar (it looks like a capital T). Click anywhere on the page where you want the new text to appear, and a text box will open. Type your content. The new text will use a default font and size — you can select it and change the formatting using the toolbar options.
You can also add shapes like rectangles, circles, or lines using the drawing tools in the toolbar. These are useful for highlighting areas or creating straightforward diagrams, but they are not as flexible as the text and image editing tools.
Saving Your Changes
As you edit, Acrobat saves your changes automatically to the original PDF file. If you want to keep the original unchanged and save your edits to a new file instead, go to File > Save As and give it a new name. This creates a copy with your changes while leaving the original untouched.
If you have made changes and want to undo them, use Ctrl+Z (or Cmd+Z on Mac) to step backward through your edits one at a time. You can also go to Edit > Undo to see a list of recent changes and jump back to any of them.
When to Use OCR for Scanned PDFs
If your PDF is a scanned image of a printed document, the text is not actually text — it is a picture of text. Clicking on it in Edit PDF mode will not let you change the words. Instead, you need to use OCR (optical character recognition), which reads the image and converts it to actual editable text.
In paid Acrobat, go to Tools > Recognize Text > In This File. Acrobat will scan the document and convert the image to text. This usually takes a minute or two depending on the file size. Once it is done, you can use the Edit PDF tool normally. OCR is not perfect — it can misread handwriting or unusual fonts — so check the results before you rely on them.
The free Reader does not have OCR. If you need to edit a scanned PDF and do not want to pay for Acrobat, you can upload it to Google Drive, open it with Google Docs, and Google will run OCR automatically. You can then read the result as a Word file or PDF.
Frequently Asked Questions
Can I edit a PDF that is password protected?
If the PDF is protected with a password that restricts editing, you will not be able to use the Edit PDF tool until you remove the protection. Go to File > Properties > Security to see what restrictions are in place. If you know the password, you can remove the restriction there. If you do not know the password, you cannot edit the file in Acrobat.
Why does my text look different after I edit it?
This usually happens when the PDF uses a font that is not installed on your computer. Acrobat substitutes a similar font, which can change the appearance. To avoid this, try to use fonts that are common on most computers, like Arial, Times New Roman, or Helvetica. You can also embed the font in the PDF before sharing it, but this requires going to File > Properties > Fonts.
Can I add pages to a PDF in Acrobat?
Yes, but not with the Edit PDF tool. Instead, go to Tools > Organize Pages > Insert, then choose whether to insert a blank page or a page from another PDF file. This is different from adding text boxes — it actually adds new pages to the document structure.
What is the difference between Acrobat and Acrobat Reader?
Acrobat Reader is free and lets you view, search, and annotate PDFs (add comments and highlights). Acrobat is paid and includes editing tools, OCR, form creation, and other advanced features. If you only need to read PDFs or add comments, Reader is enough. If you need to change the actual content, you need paid Acrobat.
Can I undo changes after I close the PDF?
No. Once you close the file, the undo history is lost. If you saved your changes, they are permanent. This is why it is a good idea to use Save As to create a backup of the original before making major edits.
