An honest iPhone guide

How to edit a PDF on iPhone, and when to switch screens

To edit a PDF on iPhone, open it in the Files app and tap Markup (the pen icon) to add text, highlights, drawings or a signature. Markup can’t change the words already on the page. To rewrite existing text or fix the layout, open the same PDF in Publish Media Software on an iPad or computer; the site opens on iPhone for viewing.

On iPhone, PublishMedia is for viewing; edit on an iPad or computer.

Opening and viewing PDFs is free on any device; editing and export need a paid plan.

Can you edit the text of a PDF on an iPhone?

Not with Apple’s built-in tools. Markup in the iPhone Files app adds new text, highlights, drawings and signatures on top of the page, but it can’t change words that are already there. To rewrite them, open the PDF in Publish Media Software (PublishMedia) on an iPad or computer, or use a paid Adobe Acrobat subscription.

Three ways to start, wherever your PDF is

First get the PDF onto an iPad or computer: AirDrop it, email it to yourself or save it to iCloud Drive.

Open it on an iPad or computer

Sign in at publishmediasoftware.com in Safari on an iPad, or in a modern browser on a computer, and drop the PDF in.

Why the PDF editor works best on an iPad or computer

Changing a PDF’s existing text means selecting small text boxes and placing items precisely, and that work needs room.

Every page is editable

Text boxes, pictures and shapes can each be selected, moved, resized or retyped.

Make it editable

Pages that open as pictures can be rebuilt into editable text and pictures on a paid plan, with OCR for scanned pages.

Import Report

Before you edit, it tells you if a font was replaced, so you know which lines to compare.

Print-ready export

Export a clean PDF on a paid plan, then email or AirDrop it back to your iPhone to share.

How to edit a PDF from your iPhone, step by step

Step 1 happens on your iPhone; steps 2 to 4 happen on an iPad or computer.

1

Send the PDF to a bigger screen

In the Files app, tap Share and AirDrop the PDF to your iPad or Mac, email it to yourself, or save it to iCloud Drive.

2

Open it in PublishMedia

On the iPad or computer, sign in at publishmediasoftware.com and drag the PDF in or browse to it. Each page opens in the page editor.

6 ways to edit a PDF on an iPhone, compared

Some of these change the words on the page; others only add new marks on top. Each card says which.

As of October 2026, an iPhone can add to a PDF but cannot rewrite it with built-in tools. Markup in Apple’s Files app adds text, highlights, drawings and signatures on top of the page. Adobe Acrobat Reader’s mobile app views, comments, fills and signs at no cost; changing existing text requires a paid Acrobat subscription. Publish Media Software (PublishMedia) opens PDFs for viewing on iPhone and edits existing text, pictures and layout in a browser on an iPad or computer, with All-Access at $99 a year or Monthly at $9.99. Smallpdf, iLovePDF and Sejda offer browser tools with limited no-cost tiers.

1. Publish Media Software (changes existing text)

View the PDF on your iPhone, then edit it in a browser on an iPad or computer: retype text, swap pictures, move items, add pages. Viewing costs nothing; editing and export are $99 a year or $9.99 a month.

2. Markup in the Files app (adds on top)

Built into the iPhone. Tap the pen icon to add text, highlights, drawings and your signature. Limit: the original words stay exactly as they are; you can cover them, but not change them.

3. Adobe Acrobat app (adds on top; text changes are paid)

Adobe’s mobile app views, comments on, fills in and signs PDFs at no cost. Changing the existing text needs a paid Acrobat subscription, and fine edits on a phone screen take patience.

4. Preview on a Mac (adds on top)

AirDrop the PDF to a Mac and open it in Preview, which comes with macOS. It adds text boxes, signatures and highlights and reorders pages with a mouse and keyboard. Limit: it can’t rewrite existing paragraphs either.

5. Smallpdf, iLovePDF or Sejda (varies)

Browser-based PDF tools you can reach in Safari. Their no-cost tiers have usage limits, and each offers paid plans. Limit: what each one can change varies, and detailed work is hard on a small screen.

6. Ask for the original file (changes everything)

If the PDF came from Word or Pages, the sender can fix the source document and export a new PDF. That usually gives the cleanest result. Limit: you depend on someone else having the file and the time.

What it costs to finish your iPhone PDF in PublishMedia

Looking at the PDF costs nothing: the Free plan opens and views unlimited files on any device and keeps them for 7 days, with a reminder email before deletion. Editing and exporting on your iPad or computer need a paid plan, either All-Access at $99 a year (Recommended) or Monthly at $9.99, cancel anytime, which also adds every template, saved projects and unlimited storage.

Editing PDFs on iPhone: questions and answers

How do I sign a PDF on my iPhone?+

Open the PDF in the Files app, tap the Markup pen icon, then tap the plus button and choose Add Signature. Draw your signature with a finger, tap Done and drag it into place. The signature sits on top of the page as a drawing, which suits most everyday forms but isn’t the same as Adobe Acrobat’s signing tools.

How do I add text to a PDF on an iPhone?+

In the Files app, open the PDF, tap the Markup pen icon, tap the plus button and choose Text. A text box appears; tap it to type, then drag it where you want it and use the format options to change the size and color. The new words sit on top of the page and don’t replace anything.

Why can’t Markup change the words in my PDF?+

Markup is an annotation tool: it lays new marks on top of the page and leaves the original content untouched. Changing the words already in a PDF means rebuilding the text itself, which takes a full editor such as Publish Media Software on an iPad or computer, or a paid Adobe Acrobat subscription.

Can I edit a PDF with PublishMedia on my iPhone?+

You can open and view PDFs in Publish Media Software on an iPhone, but the editor is built for larger screens, so editing on a phone isn’t comfortable. Sign in with the same account on an iPad in Safari or on any computer to change the text and layout, then send the finished PDF back to your phone.

How do I get a PDF from my iPhone to my computer?+

AirDrop is quickest for a Mac or iPad: in the Files app, tap Share, then AirDrop, and pick the device. For a Windows PC or Chromebook, email the PDF to yourself, or save it to iCloud Drive and get it from iCloud.com in the browser. Then drag it into PublishMedia.

Where do PDFs from Mail and Safari end up on an iPhone?+

PDFs you save end up in the Files app. In Mail, tap the attachment, tap the Share button and choose Save to Files; in Safari, tap the Share button and choose Save to Files. Items downloaded in Safari usually go to the Downloads folder in iCloud Drive or On My iPhone.

Can I complete a PDF form on my iPhone?+

Yes. Adobe Acrobat Reader’s mobile app fills in and signs forms at no cost, and Markup in the Files app can place typed text over the blanks of a form. Form fields aren’t a Publish Media Software feature, so complete forms with these phone tools instead.

Can I use PublishMedia in Safari on an iPad?+

Yes, Publish Media Software runs in Safari on an iPad with nothing to install, and that’s the best Apple mobile device for changing a PDF’s text. Sign in at publishmediasoftware.com, open the PDF from the Files app and make your changes on the larger screen. There is no separate iPhone or iPad app.

How much does it cost to change text in a PDF from my iPhone?+

Changing existing text through Publish Media Software needs a paid plan, used on an iPad or computer: All-Access at $99 a year or Monthly at $9.99, cancel anytime. Viewing the PDF on the iPhone itself costs nothing. Apple’s Markup comes with the iPhone at no charge but only adds on top of the page.
