The fastest way to edit a PDF in Adobe

Adobe Acrobat Reader (the free version) lets you add comments and fill forms, but cannot edit the actual text or images in a PDF. To change what's already written or drawn on the page, you need Adobe Acrobat Pro, which costs money, or you can use the free web version of Adobe Acrobat online.

The web version works in any browser and handles basic edits without installing software. Open your PDF at adobe.com, sign in with a free Adobe account, and use the Edit PDF tool. For permanent changes you want to keep, Acrobat Pro is more reliable, but the web version is genuinely free and works for most people who edit PDFs once or twice a year.

Key Takeaways

  • Adobe Acrobat Reader (free) cannot edit text or images—it only lets you comment and fill forms.
  • Adobe Acrobat Pro costs money but gives you a full text and image editor built into the desktop app.
  • The free web version at adobe.com lets you edit PDFs in your browser without paying or installing anything.
  • Text edits work best on PDFs created from digital documents; scanned images of pages are harder to edit in any tool.
  • After editing, always download and save your file, because web versions do not auto-save to your computer.

Editing text in Adobe Acrobat Pro

Open your PDF in Acrobat Pro and click the Edit PDF tool in the right panel. The cursor changes to a text cursor, and you can click directly on any text to select and change it. Highlight the words you want to replace, type the new text, and it overwrites the old text in place.

If you need to add text that was not there before, click in the blank space where you want it and start typing. Acrobat creates a new text box. You can resize the box by dragging its corners, and you can change the font, size, and color using the toolbar at the top. When you are done, click outside the text box to finish editing that section.

One common mistake: if the text does not let you click and edit it, the PDF may be a scanned image rather than a real text document. Scanned PDFs need optical character recognition (OCR) to become editable. In Acrobat Pro, go to Tools > Enhance Scans > Enhance, and Acrobat will attempt to convert the image to text you can edit. This works well for clean, straight pages and poorly for handwriting or tilted text.

Editing images and drawings in Adobe Acrobat Pro

Click the Edit PDF tool, then click on any image or shape in the document. A selection box appears around it. You can drag it to move it, resize it by dragging the corners, or delete it by pressing Delete.

To replace an image entirely, delete the old one and then click the image icon in the toolbar to insert a new image from your computer. Acrobat places it where you clicked. You can also draw shapes and lines using the drawing tools in the toolbar—click the shape tool, choose a rectangle, circle, or line, and draw it on the page.

If you need to crop or rotate an image, right-click it and look for crop or rotate options. Not all image edits are available in Acrobat; for complex image work like removing backgrounds or adjusting colors, you may need to edit the image in a separate program like Photoshop or Preview (on Mac), then replace it in the PDF.

Using the free Adobe Acrobat web editor

Go to adobe.com and look for the free PDF tools section. Click Edit PDF and upload your file. You do not need to pay or create an account for basic edits, though signing in with a free Adobe ID lets you save your work to the cloud.

The web editor works much like Acrobat Pro: click on text to edit it, click on images to move or delete them, and use the toolbar to add new text or shapes. The main difference is that the web version is slower and has fewer advanced options. For most people editing a PDF once or twice, it is more than enough.

After you finish editing, click the download button to save the file to your computer. The web version does not automatically save to your computer—you must download it yourself, or it stays only in your Adobe cloud storage. If you close the browser without downloading, your edits may be lost.

When you cannot edit text in a PDF

Some PDFs are locked by the creator to prevent editing. You will see a message saying the document is protected or restricted. In Acrobat Pro, go to Tools > Protect > More Options to see what restrictions are in place. If the PDF has a password, you need that password to unlock it for editing.

If the PDF is a scanned image (a photograph of a printed page), the text is not actually text—it is a picture of text. Neither Acrobat Reader nor the free web editor can edit it directly. Acrobat Pro can run OCR to convert the image to editable text, but this works only if the scan is clear and straight. Handwritten text, faded printing, or tilted pages will not convert well.

If you own the original document (a Word file, Excel spreadsheet, or email), edit that instead and export it as a PDF. This is faster and cleaner than trying to edit the PDF after the fact. If you do not own the original, ask the person who created the PDF to send you the source file.

Saving and sharing your edited PDF

In Acrobat Pro, click File and then Save to overwrite the original file, or Save As to create a new file with a different name. Saving keeps all your edits in the PDF. If you want to send the file to someone else, use File > Send for Review or simply attach it to an email.

In the web editor, click the download button to save the file to your computer. You can also share a link to the document if you are signed into your Adobe account, but the person you share with will only be able to view it unless you give them editing permission.

Before you share, check that you have not left any comments or notes you meant to delete. Click the Comments panel on the right to see all comments, and delete any you do not want the recipient to see. Comments are separate from the actual text edits, so deleting a comment does not change the document itself.

Frequently Asked Questions

Can I edit a PDF in Adobe Acrobat Reader for free?

No. Acrobat Reader is free but only lets you comment, highlight, and fill forms. To change the actual text or images, you need Acrobat Pro (paid) or the free web editor at adobe.com. The web version is genuinely free and works in any browser.

What is the difference between Acrobat Pro and the free web editor?

Acrobat Pro is installed on your computer and has more tools and faster performance. The web editor works in your browser and is slower but free. For basic edits, the web version is fine. For heavy editing or advanced features, Acrobat Pro is worth the cost.

How do I edit text in a scanned PDF?

Acrobat Pro can run OCR (optical character recognition) to convert the scanned image to editable text. Go to Tools > Enhance Scans > Enhance. This works well for clean, printed pages but poorly for handwriting or tilted scans. If OCR fails, you may need to retype the text manually.

Why can't I edit the text in my PDF?

The PDF may be locked by the creator, or it may be a scanned image rather than a real text document. Try opening it in Acrobat Pro and checking Tools > Protect to see if it is password-protected. If it is a scan, use OCR to convert it. If neither works, ask the creator for the original file.

Do I need to pay for Adobe Acrobat Pro to edit PDFs?

No. The free web editor at adobe.com lets you edit text and images without paying. Acrobat Pro costs money but offers more features and better performance. Choose based on how often you edit PDFs and how complex your edits are.
