How to Edit a PDF on an iPhone or iPad?

To edit a PDF on an iPhone or iPad, use built-in Markup tools for basic changes or third-party apps for advanced edits. 1. For simple edits like signing, highlighting, or adding notes, open the PDF in Files, Mail, or Notes, tap the Markup icon (?), add text, drawings, shapes, or signatures via the " " button, and tap "Done" to save. 2. To edit existing text, use apps like Adobe Acrobat Reader or PDF Expert: in Adobe Acrobat, tap “Edit PDF” to modify text, insert images, or manage pages; in PDF Expert, tap “Edit” to revise text like in a Word document, ideal for text-based PDFs. 3. For scanned PDFs, use OCR-enabled apps such as Adobe Acrobat, PDF Expert, or Microsoft Lens to convert images into editable text. Always backup the original file, use an Apple Pencil for precision, organize files in folders, and leverage cloud integration with iCloud, Dropbox, or Google Drive for seamless access. Basic edits are possible natively, but full content changes require dedicated apps, ensuring flexibility and efficiency in PDF editing on iOS devices.

Editing a PDF on an iPhone or iPad is easier than many people think, especially with the right tools built into iOS and third-party apps that enhance functionality. While the native Files app and Markup tools can handle basic edits, more advanced changes may require additional apps. Here’s how to edit a PDF effectively on your Apple device.

Use the Built-in Markup Tool for Basic Edits

The quickest way to make simple changes to a PDF is using Apple’s built-in Markup feature:

1. Open the PDF

   
   • Find your PDF in the Files app, Mail, Notes, or Messages.
   • Tap on the file to open it.

2. Tap the Markup icon

   • Look for the pen-tip icon (?) in the toolbar at the top or bottom of the screen.
   • If you don’t see it, tap “Edit” or “Markup” depending on where you opened the file.

3. Edit the document
   You can now:

   
   • Add text: Tap the " " button and choose “Text” to insert a text box.
   • Draw or sign: Use the pen, pencil, or highlighter tools.
   • Insert shapes or signatures: Tap the " " button to add shapes or save a signature.
   • Erase or resize elements: Use the eraser or select items to adjust size and position.

4. Save your changes

   • Tap “Done” or the checkmark.
   • The edited PDF will automatically save over the original (unless you duplicate it first).

This method is perfect for signing documents, adding notes, or highlighting text—but not for editing existing text within the PDF.

Edit Text in a PDF Using Third-Party Apps

If you need to change actual text content (like fixing a typo or rewriting a paragraph), the native tools won’t let you do that directly. You’ll need a dedicated app. Here are two reliable options:

1. Adobe Acrobat Reader (Free with optional premium features)

• Download Adobe Acrobat from the App Store.
• Open the PDF in Acrobat or import it from Files.
• Tap the Edit PDF tool.
• You can:
  • Add or modify text.
  • Insert images.
  • Reorder, rotate, or delete pages.
• Save and export when done.

2. PDF Expert by Readdle (Popular paid option)

• Known for its smooth interface and powerful editing.
• Open your PDF and tap the “Edit” button.
• Modify text as if it were a Word document (in supported formats).
• Works best with text-based PDFs (not scanned documents).
• Supports links, outlines, and annotations.

Note: If your PDF is a scanned image (like a photo of a document), you’ll need OCR (Optical Character Recognition) to make text editable. Apps like Adobe Acrobat, PDF Expert, or Microsoft Lens can convert scanned PDFs into editable formats.

Tips for a Better PDF Editing Experience

• Always keep a backup before editing, especially if overwriting the original.
• Use a stylus or Apple Pencil (on iPad) for more precise drawing or handwriting.
• Organize with folders in the Files app to quickly locate PDFs.
• Consider cloud integration—many apps sync with iCloud, Dropbox, or Google Drive.

Editing a PDF on an iPhone or iPad doesn’t require a computer. For basic markups, the built-in tools are more than enough. For deeper edits like changing text, go with trusted apps like Adobe Acrobat or PDF Expert. With a few taps, you can sign, annotate, or revise PDFs wherever you are.

Basically, it comes down to what kind of edit you need—light touch-ups or full content changes. Pick the right tool, and you're good to go.
