The simplest way to add text to a PDF

Most PDF readers let you type directly onto a PDF without converting it or using a separate tool. Open your PDF in Adobe Acrobat Reader (the free version), click the pencil icon in the toolbar, and select "Add Text". Click where you want to type and start writing. The text stays in that spot when you save.

If you don't have Acrobat Reader, download it free from adobe.com. Other free readers like Foxit Reader and Preview (on Mac) also have text-adding features, though they work slightly differently. The trade-off: free tools usually let you add text but offer fewer formatting choices than paid software.

Before you start, decide whether you need the text to look polished or just legible. A quick note on a form needs only the basic text tool. A document you're sending to others might need you to match fonts or adjust spacing, which takes more steps.

Key Takeaways

  • Adobe Acrobat Reader's free version includes a text tool — open your PDF, click the pencil icon, select "Add Text", and click where you want to type.
  • Mac users can open PDFs in Preview, click the text tool in the toolbar, and type directly without downloading extra software.
  • If you need to change fonts, colors, or text size, paid software like Adobe Acrobat Pro or alternatives like PDFtk offer more control than free readers.
  • Text you add stays in place when you save, but some free tools may not preserve formatting if the PDF is opened in a different program later.

Adding text in Adobe Acrobat Reader (Windows and Mac)

Open your PDF in Acrobat Reader. In the toolbar at the top, look for the pencil icon (it may say "Edit PDF" or show a pencil symbol). Click it, then select "Add Text" from the menu that appears.

Click anywhere on the page where you want to type. A text box will appear with a blinking cursor. Type your text. To move the text box, click and drag it. To resize it, grab the corner handles and pull. When you're done, click outside the text box to finish editing that section.

To change the font, size, or color, right-click the text box and select "Properties". A panel will open on the right side where you can adjust appearance. Save your PDF when finished — use File > Save or press Ctrl+S (Windows) or Command+S (Mac).

Adding text on Mac using Preview

Preview, the built-in Mac app, can add text to PDFs without downloading anything. Open your PDF in Preview (or right-click the file and select "Open With" > "Preview"). Click the toolbox icon in the toolbar — it looks like a wrench. Select the text tool (the "A" icon).

Click on the PDF where you want to add text. A text box appears. Type your message. To adjust font, size, or color, select the text first, then use the Format menu at the top of the screen. Save the file when done using File > Save.

When you need more control: paid PDF editors

Free tools work for simple tasks like filling in forms or adding a quick note. But if you need to match existing text styles, add multiple text boxes with different fonts, or create a polished document, paid software gives you better options.

Adobe Acrobat Pro (the paid version, separate from the free Reader) lets you edit text as if it were in a word processor, change fonts throughout a document, and adjust spacing precisely. Other paid alternatives include PDFtk, Nitro Pro, and iLovePDF Pro. These range from $10 to $15 per month or $100 to $200 per year, depending on the tool.

If you only need to add text occasionally, the free tools in Acrobat Reader or Preview usually do the job. Reserve paid software for documents you create regularly or need to send to clients.

Text that won't stay in place: why it happens and how to fix it

Sometimes text you add in a free tool disappears or moves when someone else opens the file. This happens because free readers don't always embed text the same way paid software does. The text is there in your version, but the other person's program doesn't recognize it.

To prevent this, save your edited PDF in the same program you used to edit it. If you added text in Acrobat Reader, save it there. If you used Preview, save it there. Avoid opening the file in a different program and saving it again — that can strip out the text you added.

If you need the text to survive being opened in any PDF reader, use Adobe Acrobat Pro or convert the PDF to a Word document first, add your text there, and export it back to PDF. This takes more steps but guarantees the text stays put.

Adding text to forms and fillable PDFs

Some PDFs are designed as forms with blank spaces ready for typing. These "fillable" PDFs have form fields built in. When you open one, you'll see boxes or lines where text belongs. Click in any box and type — the form handles spacing and alignment automatically.

If a PDF looks like a form but the boxes don't respond to clicks, it's a scanned image, not a fillable form. You'll need to use the text tool instead and manually position your text. Fillable forms are easier because they guide where your text goes.

After filling out a form, save it the same way you would any edited PDF. Most programs let you save a filled form as a new file so you keep the blank original.

Frequently Asked Questions

Can I add text to a PDF on my phone?

Yes. Adobe Acrobat Reader has a mobile app for iPhone and Android with a text tool. Open your PDF, tap the pencil icon, select "Add Text", and tap where you want to type. Other apps like Foxit and iLovePDF also work on phones, though the small screen makes precise placement harder than on a computer.

What if the PDF is password-protected?

If the PDF is locked for editing, you won't be able to add text until you unlock it. Some PDFs are locked with a password you can enter. Others are locked by the creator and can't be unlocked without their permission. Try opening it in your PDF reader — if it asks for a password, enter it. If it doesn't ask, the file is locked and you'll need the creator to unlock it.

Does adding text to a PDF change the original file?

When you save, the text becomes part of that PDF file. The original is only changed if you save over it. To keep the original blank, use "Save As" instead of "Save" and give the file a new name. This creates a separate file with your text while leaving the original untouched.

Can I add text to a scanned PDF?

Yes, but the text won't align with the scanned content the way it would on a regular PDF. Scanned PDFs are images, so text you add floats on top rather than fitting into the document structure. For better results, use optical character recognition (OCR) software to convert the scanned image to editable text first, then add your text. Many PDF readers include OCR as a built-in feature.
