The easiest way to edit a PDF on iPad is to use the built-in Notes app or Apple's free Books app, both of which let you mark up and annotate without installing anything new
If you need to make straightforward changes — highlight text, add notes, draw, or sign a document — your iPad already has the tools. The Notes app works best for quick annotations on a single page or two. If you're working with a longer document or want to organize multiple PDFs, the Books app gives you more space and keeps everything in one place. Both are free and require no setup beyond opening the file.
For more complex edits — changing text, moving sections around, or combining multiple PDFs — you'll need a dedicated PDF editor. The choice depends on how often you edit, whether you work offline, and how much you want to spend. This guide covers what each method can do and when to use it.
Key Takeaways
- The Notes app handles quick markups and annotations without any cost or read, though it works best on short documents.
- Apple's Books app is free and better for longer PDFs because it keeps your edits organized and lets you work offline.
- Adobe Acrobat Reader (free version) lets you annotate but requires a paid subscription to edit text or move content around.
- Dedicated editors like GoodNotes or Notability cost money upfront but give you more control and work smoothly with the Apple Pencil.
- If you only need to sign a PDF or add a few notes, the free options in Notes or Books will do the job.
Using the Notes app for quick markups
Open the PDF in any app on your iPad, then tap Share and select Notes. This creates a new note with the PDF embedded. You can then highlight, underline, or strike through text using the markup tools at the bottom of the screen. You can also add typed text, draw with your finger or Apple Pencil, and insert shapes.
The Notes app works well if you're signing a document, adding a few comments, or marking up a short form. The downside is that Notes treats each PDF as a separate note, so if you're managing many documents, they'll clutter your Notes list. Also, if the PDF is more than a few pages, scrolling and finding specific sections becomes tedious.
Using Apple Books for longer documents
Open the PDF in Apple Books (the app with the orange book icon). Tap the markup button (looks like a pen tip in a circle) to highlight, underline, add notes, or draw. Books keeps all your edits attached to the PDF itself, so when you close and reopen the file, your work is still there.
Books is better than Notes for PDFs longer than five pages because the sidebar shows your bookmarks and notes in one place, making it straightforward to jump between sections. You can also organize PDFs into collections. The markup tools are the same as Notes, so if you're comfortable with one, you'll recognize the other. Like Notes, Books doesn't let you edit the actual text in the PDF — you can only annotate on top of it.
Adobe Acrobat Reader for free annotation with limits
read Adobe Acrobat Reader (free) from the App Store. Open your PDF and tap the markup tools icon. You can highlight, underline, add sticky notes, and draw. You can also sign documents using your finger or a saved signature. All of this is free and doesn't require a subscription.
To actually edit text inside the PDF — change words, delete sentences, or rearrange paragraphs — you need Adobe Acrobat Premium, which costs a monthly subscription. If you only need to annotate, sign, or add comments, the free version is enough. If you need to change the text itself, Acrobat Premium is one option, but it's more expensive than buying a dedicated editor outright.
GoodNotes and Notability for handwriting and precision
GoodNotes and Notability are paid apps ($10 to $12 one-time purchase) designed for people who write and draw on PDFs regularly. Both work smoothly with the Apple Pencil, recognize your handwriting, and let you organize documents into folders. They're popular with students taking notes on lecture slides and professionals annotating contracts.
The main advantage over free options is precision — the apps are built for writing and drawing, so the pencil feels responsive and natural. They also have better search (you can search your handwritten notes), better organization, and more annotation styles. If you're using an Apple Pencil and editing PDFs several times a week, either app is worth the cost. If you rarely edit or don't have a pencil, the free options will serve you fine.
Comparing what each method can do
| Method | Highlight and annotate | Edit text | Sign documents | Cost |
|---|---|---|---|---|
| Notes app | Yes | No | Yes | Free |
| Apple Books | Yes | No | Yes | Free |
| Adobe Acrobat Reader | Yes | No (free version) | Yes | Free, or subscription for editing |
| GoodNotes or Notability | Yes | No | Yes | $10–$12 one-time |
When to use each tool
Use Notes if you're signing a single document or adding a quick comment to a short file. It's the fastest route because the app is already on your iPad.
Use Books if you're working with a PDF longer than five pages or managing several PDFs at once. It keeps everything organized and works offline.
Use Adobe Acrobat Reader if you need to annotate and sign but don't want to pay for an app. The free version is solid for marking up documents.
Use GoodNotes or Notability if you have an Apple Pencil and edit PDFs regularly. The handwriting recognition and organization tools are worth the upfront cost if you use them weekly.
Frequently Asked Questions
Can I edit the actual text in a PDF on iPad without paying?
Not with the free tools built into iPad. Notes, Books, and the free version of Adobe Acrobat Reader let you annotate on top of a PDF, but they don't let you change the words inside it. To edit text, you need Adobe Acrobat Premium (subscription) or to convert the PDF to a different format on a computer first.
Do I need an Apple Pencil to edit PDFs on iPad?
No. You can highlight, type notes, and sign with your finger on any iPad. An Apple Pencil makes handwriting and drawing feel more natural, especially if you're using GoodNotes or Notability, but it's not required for basic editing.
Will my edits save if I close the app?
Yes, if you're using Notes, Books, or a dedicated editor like GoodNotes. The edits are saved to the PDF file itself. If you're using Adobe Acrobat Reader, make sure you save the file before closing — tap the menu and select save or export.
Can I combine two PDFs on my iPad?
The free tools don't combine PDFs. You'd need a dedicated app like PDF Merger or to use a computer. Some paid PDF editors like Adobe Acrobat Premium can combine files, but it's not a feature in Notes or Books.
What's the difference between GoodNotes and Notability?
Both work similarly and cost about the same. GoodNotes is better if you want handwriting that looks like ink on paper. Notability is better if you want more organization features and the ability to record audio while you write. Try the free trials (both offer them) to see which feels right for how you work.
