How to Add Text to a PDF for Free (Type on Any PDF)
Add text to a PDF free — fill a blank line or annotate with macOS Preview, Acrobat Reader Fill & Sign or your browser, plus the Word route for heavy edits.

You've got a PDF that needs a few words added — a name on a form, a note in the margin, a date on a blank line. You don't want to print it, write by hand, and scan it back. Good news: typing text onto a PDF is free on every platform. Let's do it the fast way.
First, a straight answer about pdfty: we don't have a browser tool that lets you click anywhere on a PDF and type free-floating text. For that specific job the built-in tools below are better, and we'll point you straight to them. Where pdfty genuinely helps is the heavy-edit case — converting to Word so you can retype whole paragraphs — covered at the end.
macOS Preview — the fastest on a Mac
Preview ships with every Mac and adds text boxes offline.
Open the PDF in Preview
Double-click the file. Preview is the default PDF viewer on macOS.
Open the markup toolbar
Click the pen-tip icon, or Tools → Annotate → Text. A text box appears.
Type and position
Drag the box onto the blank line, type your text, then use Font (the A icon) to match size and color.
Export a copy
File → Export as PDF so you keep the original untouched.
Done
Your text is baked into the page. Send it on.
Preview is truly local — nothing uploads — so it's the right choice for anything sensitive.
Free Adobe Acrobat Reader — best on Windows
The free Reader (not paid Pro) has a Fill & Sign mode built for exactly this.
- Open the PDF in Acrobat Reader.
- Click Fill & Sign (in the right-hand tools panel or under Tools).
- Click any spot on the page and start typing. The Ab cursor drops a text field wherever you click.
- Resize text with the small/large A buttons; add checkmarks and dots for checkboxes.
- File → Save As to keep the filled copy.
Fill & Sign works on flat forms (just lines printed on the page) as well as interactive ones, which is why it's the most reliable free option on Windows.
Your browser — for interactive forms
If the PDF is an interactive form (the fields highlight when you hover), you can fill it right in the browser:
- Open the PDF in Chrome, Edge or Firefox.
- Click into each field and type.
- Print → Save as PDF to export the filled version.
The limit: browsers can only fill existing form fields. They can't add free-floating text to a flat PDF — use Preview or Reader for that.
Filling a form vs. adding text vs. editing text
These sound the same but aren't — and the right tool depends on which one you mean.
| Task | What it means | Best free tool |
|---|---|---|
| Fill a form | Type into blank lines/fields on a form | Acrobat Reader Fill & Sign, or Preview |
| Add a note / label | Drop free-floating text anywhere | Preview (Mac) or Reader (Windows) |
| Rewrite existing text | Change words already printed in the PDF | [PDF to Word](/en/tools/pdf-to-word) round-trip |
| Add a signature | Sign a contract or form | pdfty [Sign PDF](/en/tools/sign-pdf) |
Heavy edits: convert to Word, type, convert back
If you need to change text that's already in the PDF — retype a paragraph, fix a whole sentence, update several numbers — text boxes on top won't cut it. PDF body text isn't stored as editable paragraphs, so the reliable free route is a round-trip through Word:
Convert to Word
Upload the PDF to PDF to Word. You get a .docx with editable paragraphs.
Type freely
Open it in Word, Google Docs or Pages and add or change whatever text you want — it's a normal document now.
Export back to PDF
Run the edited file through Word to PDF for a clean PDF.
Done
No white-box hacks, no watermark, real text changes.
This shines for text-heavy, simple layouts (letters, forms you're rebuilding, reports). If the PDF is a scan (an image with no text layer), run OCR first so there's real text to extract.
Frequently asked questions
Does pdfty have a tool to type text directly onto a PDF?
No. We're honest about this: pdfty has no in-browser "add text" tool. To type on a blank line, use macOS Preview or the free Acrobat Reader Fill & Sign. To change text that's already there, use our PDF to Word → Word to PDF round-trip. To sign, use Sign PDF.
How do I add text to a PDF on Windows without buying anything?
Install the free Adobe Acrobat Reader, open the PDF, choose Fill & Sign, click where you want text and type. It's free and works on flat forms too.
How do I add text on a Mac?
Open the PDF in Preview, click the markup toolbar, pick Text, and drag the box where you want it. Export as PDF when done. No install needed.
Can I add text to a PDF on my phone?
On iPhone/iPad, open the PDF and tap the Markup pen, then the + to add a text box. On Android, the free Acrobat Reader app offers the same Fill & Sign flow.
Why can't I just type over the existing words?
Because PDF text is stored as positioned glyphs, not editable paragraphs. Typing "over" it means covering it with a box — which breaks if anything reflows. For genuine changes, use the Word round-trip.
My PDF is a scan — the text won't select. What do I do?
It's an image. Run OCR to add a searchable text layer, then either annotate it or send it through PDF to Word to edit.
Will adding text leave a watermark?
Not with Preview, the free Acrobat Reader, or pdfty's converters. Some online "free" text tools stamp a logo — check before downloading.
The PDF is password-protected and won't let me add text. Now what?
Remove the password first with Unlock PDF (you'll need to know it), then add your text to the unlocked copy.
