You can edit a PDF in Adobe Acrobat Reader or Acrobat Pro, but the steps differ between them

Adobe Reader (the free version) lets you fill in forms and add comments, but cannot edit the actual text or images in a PDF. If you need to change words, move text around, or replace images, you need Adobe Acrobat Pro, which costs a monthly subscription. The free Reader is useful for marking up a document with notes and highlighting, but those marks stay separate from the PDF itself — they do not change what the document says.

Before you start, check what you actually need to do. If you are filling in blanks on a form, Reader works fine. If you are rewriting sentences, moving paragraphs, or swapping out images, you will need Acrobat Pro or a different tool altogether.

Key Takeaways

  • Adobe Reader (free) can fill forms and add comments, but cannot change the text or images inside a PDF.
  • Adobe Acrobat Pro is the official tool for editing text, images, and page layout, and requires a paid subscription.
  • The Edit PDF tool in Acrobat Pro appears in the right panel and lets you click directly on text or images to modify them.
  • If you do not have Acrobat Pro, converting the PDF to Word, editing it there, and saving it back as a PDF is often faster and cheaper.

Editing text in Adobe Acrobat Pro

Open your PDF in Acrobat Pro and look at the right side of the screen. You should see a panel with tools listed — one of them says "Edit PDF." Click it. The document will now show a blue outline around text boxes and images, meaning they are ready to edit.

Click directly on any word or sentence you want to change. A text cursor will appear, and you can type, delete, or rewrite just like in a Word document. If the text box is too small for your new text, Acrobat will expand it automatically. When you are done editing that section, click somewhere else in the document to move to the next text box.

One common mistake: clicking on the text once selects the whole text box, and clicking again puts you in edit mode. If nothing happens when you click, try clicking a second time. If the text still will not edit, the PDF may be locked or scanned from an image — locked PDFs require a password, and scanned PDFs need optical character recognition (OCR) first, which Acrobat can do automatically if you ask it to.

Editing images in Adobe Acrobat Pro

In the same Edit PDF mode, click on any image in the document. A blue border will appear around it with small handles at the corners and edges. You can drag these handles to resize the image, or drag the image itself to move it to a different spot on the page.

To replace an image entirely, right-click on it and select "Replace Image." A file browser will open — navigate to the new image you want to use and select it. Acrobat will swap out the old image for the new one, keeping the same size and position. If you just want to delete an image, click it and press Delete.

Images in PDFs cannot be edited the way they can in Photoshop — you cannot crop, rotate, or adjust colors from within Acrobat. If you need to change what is inside an image, you will need to edit it in an image editor first, then replace it in the PDF.

Adding new text or images to a PDF

While in Edit PDF mode, look for the "Add Text" button in the right panel. Click it, then click anywhere on the page where you want the new text to appear. A text box will open and you can type. You can change the font, size, and color using the options that appear above the text box.

To add a new image, look for "Add Image" in the right panel (or right-click on the page and select it from the menu). Choose the image file from your computer. It will appear on the page, and you can resize and move it the same way you would an existing image.

New text and images you add will look slightly different from the original document — the fonts may not match perfectly, and the spacing might be off. This is normal. If the document needs to look professionally consistent, consider editing it in Word or the original program it came from, then exporting it as a PDF again.

Saving your edited PDF

Once you finish editing, go to File and click Save. Acrobat will save the changes directly into the PDF file. If you want to keep the original unchanged, use File > Save As instead and give it a new name.

If you are sharing the PDF with someone else, remember that they will see all your edits. If you added comments or marked-up sections that you do not want them to see, you need to remove those separately — comments are not the same as edits to the text itself.

When to use a different tool instead

Acrobat Pro is expensive if you only need to edit one or two PDFs. A faster option is to convert the PDF to Microsoft Word, make your changes there, and save it back as a PDF. Most PDFs convert cleanly, though complex layouts or scanned documents may not translate perfectly.

To convert a PDF to Word in Acrobat Pro, go to File > Export To > Microsoft Word. In Adobe Reader, you cannot do this directly, but you can use online conversion tools — search for "PDF to Word converter" and upload your file. The converted Word document will open in Word or Google Docs, where you can edit normally. When you are done, save it as a PDF using File > Save As and choose PDF from the format menu.

If your PDF is scanned from paper (meaning it is actually a picture of text, not real text), you will need OCR before you can edit it. In Acrobat Pro, go to Tools > Recognize Text > In This File, and Acrobat will convert the image to searchable, editable text. This takes a minute or two depending on the file size.

Frequently Asked Questions

Can I edit a PDF for free without buying Acrobat Pro?

Adobe Reader cannot edit text or images, but you can convert the PDF to Word using an online tool, edit it there, and save it back as a PDF. This works well for most documents and costs nothing. If the PDF is locked with a password, you will need to remove the password first before any tool can edit it.

Why can't I click on the text to edit it?

The PDF may be locked, scanned from an image, or the Edit PDF tool may not be active. Make sure you clicked "Edit PDF" in the right panel first. If it is a scanned PDF, use Tools > Recognize Text > In This File to convert the image to editable text. If it is password-protected, you will need the password to unlock it.

The text I added looks different from the rest of the document. How do I fix it?

PDFs do not always have the original font installed on your computer, so new text may use a substitute font. If the document needs to look consistent, edit it in the original program (Word, InDesign, etc.) instead, then export it as a PDF. If you only have the PDF, you can try matching the font manually, but it will never be perfect.

Can I edit a PDF on my phone or tablet?

Adobe offers a mobile app called Adobe Acrobat that can fill forms and add comments on phones and tablets, but full text and image editing is limited. For serious editing, use a computer with Acrobat Pro or convert the PDF to Word on your phone using an online tool.
