The simplest way to add text to a PDF

Most PDF readers let you type directly onto a PDF without converting it first. The method depends on which program you already have open. If you are using Adobe Acrobat Reader (the free version), look for a pencil or "Fill & Sign" button in the toolbar — that opens a text box you can click and type into. If you are using Preview on Mac, go to Tools in the menu bar and select Annotate, then click the text icon. On Windows, Microsoft Edge has a built-in PDF reader with a "Draw" tab that includes text tools. Google Chrome also opens PDFs and lets you print to PDF with annotations, though you cannot type directly in the viewer itself.

The text you add stays on top of the PDF without changing the original document. When you save, the program asks whether you want to save as a new file or overwrite the old one — choose "Save As" if you want to keep the original unchanged.

Key Takeaways

  • Adobe Acrobat Reader's "Fill & Sign" tool lets you click anywhere on a PDF and type text that stays in that spot.
  • Mac's Preview and Windows' Edge both have built-in text tools in their PDF readers — no separate program needed.
  • Text you add appears as an overlay on the PDF and does not alter the original document content.
  • Always use "Save As" when you finish typing so you can keep both the original and the version with your text.
  • If the PDF is locked or restricted, you may need to unlock it first through the program's security settings.

Using Adobe Acrobat Reader on Windows or Mac

Open your PDF in Adobe Acrobat Reader. Look at the right side of the toolbar — you should see a pencil icon or a button labeled "Fill & Sign". Click it. The toolbar changes to show annotation tools, including a text box icon (usually marked with an "A" or "T").

Click the text box icon, then click anywhere on the PDF where you want to type. A box appears with a blinking cursor. Type your text. The box expands as you type, and you can drag the corners to make it larger or smaller. When you are done, click outside the text box to finish editing it. To add more text elsewhere on the page, click the text icon again and repeat.

Once all your text is in place, go to File and select "Save As". Choose a new filename or location so you keep the original PDF unchanged. The program saves your version with all the text you added.

Using Preview on Mac

Open your PDF in Preview (the default Mac PDF viewer). At the top of the window, click Tools in the menu bar. A dropdown menu appears — select Annotate. The annotation toolbar appears at the bottom of the window.

Look for the text icon in the annotation toolbar (it looks like lines of text or the letter "A"). Click it, then click on the PDF where you want to add text. A text box opens with a cursor ready for typing. Type your text, and the box grows to fit what you write. Click outside the box when you are done. To add more text, click the text icon again.

When finished, press Command+S to save. Preview asks whether to save changes to the original file or create a new one — choose "Save As" to keep both versions.

Using Microsoft Edge on Windows

Open your PDF in Microsoft Edge (the default PDF viewer on Windows 10 and 11). At the top right of the window, click the pencil icon labeled "Draw". The drawing toolbar appears at the top.

In the toolbar, look for the text tool — it is usually marked with an "A" or "T" icon. Click it. Your cursor changes to a crosshair. Click on the PDF where you want to type, and a text box appears. Type your text. You can adjust the font size and color using the options in the toolbar before you click on the PDF, or after by selecting the text box and using the toolbar again.

When you are done, press Ctrl+S to save. Edge saves the PDF with your annotations included. If you want to keep the original unchanged, use "Save As" instead.

Typing into PDF forms with fillable fields

Some PDFs are designed as forms with blank spaces meant for typing. These have fillable fields — boxes that are already set up to receive text. When you open a form like this in Adobe Acrobat Reader, the program automatically detects the fields and highlights them.

Click on any highlighted field and type. The text appears inside that field only, formatted to fit. You can move between fields by pressing Tab (forward) or Shift+Tab (backward). When all fields are filled, save the form the same way you would save any annotated PDF — File, then "Save As".

If a PDF form does not have fillable fields but you still need to type into it, use the text box method described above. The text will sit on top of the form rather than inside the designed spaces, but it will still be readable and saveable.

What to do if you cannot type on the PDF

If you click on a PDF and nothing happens, the document may be locked or restricted. Some PDFs are set to prevent editing or copying. In Adobe Acrobat Reader, go to File and look for "Properties" or "Document Properties". Check whether the Security section shows any restrictions. If it does, you may need the password to unlock it, or you may need to use a different tool.

Another reason typing might not work is that the PDF is an image rather than text. This happens when someone scans a paper document and saves it as a PDF without running text recognition. You cannot type on image-based PDFs the same way — you would need to use OCR (optical character recognition) software first, or straightforward add text on top as an annotation.

If the PDF is locked and you own it or have permission to edit it, try opening it in a different program. Some PDF editors like PDFtk or Smallpdf can remove restrictions, though this requires the correct password if one was set.

Saving and sharing your typed PDF

After you type on a PDF, always save it with a new name so you have both the original and your version. Use "Save As" rather than "Save" — this prevents accidentally overwriting the original file. Name the new file something clear, like "Form_YourName_2024" or "Invoice_Marked_Up".

When you share the PDF with others, they will see all the text you added. If you want them to see only the original document without your notes, send them the original file instead. If you want to remove text you added before saving, select the text box and press Delete, or use the undo function (Ctrl+Z on Windows, Command+Z on Mac) before you save.

Frequently Asked Questions

Can I change the font or size of text I type on a PDF?

In Adobe Acrobat Reader, you can adjust font size and color before you click to create a text box — look for formatting options in the toolbar. In Preview and Edge, font options appear in the toolbar once you select the text tool. Most free readers offer basic formatting, but options are more limited than in a word processor.

What if I type something wrong — can I edit it?

Yes. Click on the text box to select it, then click inside the text to position your cursor. You can then delete, add, or change text the same way you would in any document. Some programs let you select all the text in a box and retype it completely.

Does typing on a PDF change the original document?

No, not if you use "Save As". The text you add is an overlay that sits on top of the PDF. When you save with a new filename, the original PDF stays exactly as it was. Only the new file contains your typed text.

Can I type on a PDF that is password protected?

If the PDF is locked against editing, you cannot add text unless you have the password to unlock it. Check the document properties to see what restrictions are in place. If you own the document or have permission to edit it, you can try opening it in a different PDF program or using an online tool to remove the restriction.

Is there a way to type on a PDF on my phone?

Yes. Adobe Acrobat Reader has a mobile app for iPhone and Android with the same Fill & Sign feature. Other options include Google Drive (upload the PDF and open it in Google Docs), or apps like Notability or GoodNotes on iPad. The process is similar — tap the text tool, tap where you want to type, and save when done.
