How to edit a PDF on iPhone or iPad

By Prakrin Kumar, who builds PDFPivot and VidPivot at The Nexus Pivot. Last updated 27 July 2026.

The Files app can preview a PDF, and Markup can draw, sign, and drop a text box on the page — but neither one lets you tap into the text that's already printed in the document and change it. If you need to fix a typo, update a number, or swap out a photo inside the PDF itself, here's what that actually takes on iOS.

Key takeaways

• App: An iPhone or iPad PDF app with real text and image editing, not just Markup — we use PDFPivot (our app).
• Built-in tools: Files previews a PDF; Markup annotates and signs it. Neither edits the text already inside it.
• Internet: Not needed. On-device editing works fully offline.
• Cost: Free for core editing; PDFPivot shows ads, with an optional subscription to remove them.

What's the fastest way to edit PDF text on iPhone or iPad?

Install an app that lists real text and image editing, not just annotation — Markup doesn't do this. Open the PDF from Files or the Share sheet, tap the text or image you want to change, edit it in place, and save it back to Files. No upload, no computer needed.

What can Files and Markup do for free — and where do they stop?

Files previews any PDF and lets you keep it organized — rename it, move it between On My iPhone and iCloud Drive, and open it in whatever app you need next. Markup, reachable from a Quick Look preview, the Share sheet, or inside Mail, Notes, and Photos, genuinely does a lot for free: draw, highlight, add shapes and text boxes, crop images, and add a signature.

What Markup can't do is open the text that's already part of the PDF's content and let you rewrite it. It places new marks on top of the page. A typo in the original document, or a scanned page, stays exactly as it was — you can cover it or write near it, but not correct it. That's the specific gap an app like PDFPivot fills.

It's a gap that affects a lot of people: iOS runs the majority of phones in the US, at 58.35% of the mobile market as of June 2026 according to StatCounter, and Files plus Markup is what most of them have open by default when a PDF needs a fix.

How do you edit a PDF on iPhone or iPad, step by step?

1. Install a PDF app with real text editing. We build one called PDFPivot (disclosure: it is our app) that edits text and images on-device — the file never leaves your phone or tablet. Any app that genuinely edits text, not just annotates, works the same way.
2. Open the PDF — from Files, or via the Share sheet from Mail, Photos, or another app.
3. Tap the text block or image you want to change. For text, retype it in place — the app keeps it close to the original font and position. For images, drag, resize, or replace them.
4. Save the file back to Files — On My iPhone or iCloud Drive — or share the finished PDF straight from the app using the Share sheet or AirDrop.

What can go wrong when editing a PDF on iPhone?

• Tapping the text only lets you draw or highlight. You're in Markup, not a real text editor. Look for a tool specifically labeled Edit or "edit text," not Markup or annotate.
• The PDF is a scan, so there's no text to tap into. A scanned page is a picture of text, not real text. Run OCR on it first if your app supports it — only then does the text become tappable and editable.
• The edited text doesn't quite match the original font. Some editors substitute a close system font instead of the exact one embedded in the PDF. Check the result before sending anything with strict formatting requirements.

Once the content looks right, you may also want to add a signature, shrink the file before sending it, or start from a paper original with our guide to scanning documents on iPhone. For a broader look at tools that never upload your file, see our offline PDF editors comparison.

Frequently asked questions

Can Markup edit the text already in a PDF on iPhone?

No. Markup, available from the Share sheet and Quick Look in Files, draws, signs, and adds shapes or text boxes on top of a PDF page. It can't open the existing text inside the PDF and change the words themselves. For that you need an app that specifically edits PDF text, such as PDFPivot (disclosure: it's our app).

Is there a free way to edit PDF text on iPhone?

Yes. PDFPivot edits PDF text and images on iPhone and iPad for free, supported by ads, with an optional subscription to remove the ads and the free-tier export watermark.

Does editing a PDF on iPhone upload it anywhere?

Not with an on-device app. PDFPivot processes the PDF on your iPhone or iPad and does not upload the file, its text, or your edits to a server.
