How to Edit Text, Images, and Pages in a PDF File

You can edit a PDF directly without converting it first

Most PDFs can be edited in the program you already have. If you have Adobe Acrobat Reader (the free version), you can edit text and add comments. If you have Microsoft Word, you can open a PDF and edit it like a regular document. If you have neither, free tools like Google Drive, Smallpdf, or ILovePDF let you make changes in your web browser without downloading anything.

The method you choose depends on what you need to change. Editing text works differently than replacing an image. Adding or removing pages is different still. This guide walks you through each type of edit and shows you which tool to use for each one.

Key Takeaways

Adobe Acrobat Reader (free) lets you edit text and add comments directly in the PDF without converting it.
Microsoft Word can open PDFs and edit them like regular documents, though the layout sometimes shifts.
Google Drive and free web tools like Smallpdf work in your browser and require no software download.
Editing text, replacing images, and adding or removing pages each use different steps depending on your tool.
If a PDF is locked or password-protected, you must unlock it first before any edits will work.

Edit text using Adobe Acrobat Reader

Open the PDF in Adobe Acrobat Reader. Click the pencil icon in the top toolbar (it says "Edit PDF" when you hover over it). The document switches to edit mode, and you can now click any text to change it.

Click the text you want to change. A text box appears around it. Delete the old text and type the new text. The font and size usually stay the same, but if they change, you can select the text and use the formatting buttons in the right panel to fix it. When you are done, click outside the text box to save that change.

To add text where none exists, click the "Add text" button in the right panel, then click the spot in the document where you want the new text to appear. Type your text, and it will appear in the PDF. You can move it by dragging the text box, or resize it by dragging the corners.

When all edits are complete, go to File > Save or File > Save As. If you use Save, the changes overwrite the original file. If you use Save As, you create a new file and keep the original unchanged.

Edit a PDF in Microsoft Word

Open Microsoft Word. Go to File > Open and find your PDF file. Select it and click Open. Word converts the PDF into an editable document and opens it. The layout usually stays close to the original, but complex PDFs with multiple columns or unusual formatting may shift.

Once the PDF is open in Word, edit it like any other document. Click any text to change it, delete paragraphs, add new content, or adjust formatting. Use the same tools you would use in a regular Word document — the font menu, bold and italic buttons, spacing controls, and so on.

When you finish editing, save the file. Go to File > Save As and choose your format. If you want to keep it as a PDF, select "PDF" from the format dropdown. If you want to keep it as a Word document, select "Word Document." Word will ask you to confirm your choice, and then save the file.

One limitation: if the original PDF was scanned from paper (an image-based PDF), Word cannot edit the text inside it. You would need to use a different tool for that type of file.

Edit a PDF in Google Drive

Go to Google Drive in your web browser and sign in with your Google account. Click the "New" button on the left side, then select "File upload." Find your PDF on your computer and upload it. Once it finishes uploading, right-click the file and select "Open with" > "Google Docs." Google converts the PDF into an editable document.

Edit the document the same way you would edit any Google Doc. Click text to change it, delete content, add new paragraphs, or adjust formatting. The toolbar at the top has font, size, bold, italic, and other formatting options. Changes save automatically as you work.

When you are done, download the file back to your computer. Click File > Download and choose your format. Select "PDF" to save it as a PDF, or "Microsoft Word" to save it as a Word document. The file downloads to your computer's Downloads folder.

Google Docs works well for text-heavy PDFs, but like Word, it cannot edit scanned PDFs where the text is actually an image.

Replace or remove images in a PDF

To replace an image, open the PDF in Adobe Acrobat Reader and click the pencil icon to enter edit mode. Click the image you want to replace. A selection box appears around it. Right-click the image and select "Replace Image." A file browser opens. Find the new image on your computer, select it, and click Open. The new image replaces the old one in the same spot.

To remove an image, click it to select it and press Delete. The image disappears, and the text around it may shift to fill the space. If you need to resize an image after replacing it, click the image and drag the corner handles to make it larger or smaller.

If you are using Google Drive or a web tool like Smallpdf, image replacement is usually not available. For those tools, your best option is to download the PDF, edit it in Adobe Acrobat Reader or Word, and upload the new version.

Add, delete, or rearrange pages

Open the PDF in Adobe Acrobat Reader and click the pencil icon. On the right side, you will see a panel showing all the pages in your document as thumbnails. To delete a page, right-click its thumbnail and select "Delete." The page is removed from the PDF.

To add a blank page, right-click any page thumbnail and select "Insert Blank Page." A new blank page appears after the page you right-clicked. To add a page from another PDF, right-click and select "Insert from File," then choose the PDF you want to pull a page from.

To rearrange pages, click and drag a page thumbnail to a new position. The page moves to wherever you drop it. This is useful if pages got scanned in the wrong order or if you want to reorganize sections.

Microsoft Word does not have a good way to manage pages in a PDF. If you need to add, delete, or rearrange pages, use Adobe Acrobat Reader or a web tool like Smallpdf, which has a dedicated page-management interface.

Unlock a password-protected PDF before editing

If a PDF is locked, you will not be able to edit it until you unlock it. Some PDFs are locked with a password to open them (you cannot view the file without the password). Others are locked with a password to edit them (you can view the file but cannot change it). You need the correct password to unlock either type.

If you have the password, open the PDF in Adobe Acrobat Reader. If it is a view-only lock, click the pencil icon and you will be prompted to enter the password. Type it and click OK. If it is an open password, you will be prompted as soon as you try to open the file. Enter the password and the file opens.

If you do not have the password and you own the document, contact whoever sent it to you and ask for the password. If the PDF is yours but you forgot the password, you will need to use a password-recovery tool or contact Adobe support. There is no way to edit a password-protected PDF without the correct password.

Frequently Asked Questions

Can I edit a scanned PDF where the text is actually an image?

Not with the tools described here. Scanned PDFs require optical character recognition (OCR) software to convert the image into editable text. Adobe Acrobat Pro (the paid version) has OCR built in. Free alternatives like Tesseract or online OCR tools can do this, but they are more technical to use.

What if the PDF layout gets messed up when I open it in Word?

Word sometimes reformats PDFs, especially ones with multiple columns or complex layouts. If this happens, use Adobe Acrobat Reader or Google Drive instead. Both preserve the original layout better. You can also try opening the PDF in Word, then immediately saving it as a PDF to see if the layout improves.

Do I need to download software to edit a PDF?

No. Google Drive, Smallpdf, and ILovePDF all work in your web browser without downloading anything. If you already have Word or Adobe Reader installed, you do not need to download anything either. Choose whichever tool you already have or prefer to use.

Can I edit a PDF on my phone or tablet?

Yes, but it is more difficult than on a computer. Adobe Acrobat Reader has a mobile app for iPhone and Android that lets you edit text and add comments. Google Drive also works on mobile devices. For best results, edit on a computer where you have more screen space and easier access to formatting tools.

What format should I save the edited PDF in?

Save it as a PDF if you want to keep it in the same format. If you edited it in Word and want to make more changes later, you might save it as a Word document instead, since Word documents are easier to edit than PDFs. Choose PDF if you are sending it to someone else or if you want the formatting to stay locked in place.
