How to Edit a PDF on iPhone

A simple step-by-step guide to edit a pdf on iPhone using PDFWix's free online tools.

How to Edit a PDF on iPhone

Edit a PDF on iPhone with iOS Markup for annotations or PDFWix in Safari for text edits. Free, no app install, no signup, no watermark — works on iOS 16+.

Why editing PDFs on iPhone usually costs money

iPhone ships with PDF viewing and (sometimes) annotation, but real editing — adding text, replacing images, inserting pages, redacting — is gated behind paid apps. PDFWix moves all of that into your browser, free.

What you can do natively on iPhone

Markup (in Files, Mail, Photos) lets you draw, highlight, add text and sign. It can't replace existing text, insert pages or redact. Anything beyond annotation needs a paid app — PDF Expert ($79.99/year) or Acrobat ($19.99/month) are the popular choices.

Edit a PDF on iPhone with PDFWix

Open pdfwix.com/edit-pdf in your browser. Drop in the PDF. Click anywhere on a page to add a text box, image, signature or highlight. Use the toolbar to redact, draw or insert blank pages. When done, click Download — the edited PDF saves locally with all changes baked in.

The whole workflow runs in your browser. No upload, no signup, no per-edit fee.

When you'd still want a desktop editor

Use a desktop editor (Acrobat Pro, PDF Expert) when you need structural editing — reflowing whole paragraphs, swapping embedded fonts, editing AcroForm field properties, or batch-processing dozens of files. Otherwise PDFWix is faster and free.

How it works

  1. Open the editor — Open pdfwix.com/edit-pdf in Safari or Chrome.
  2. Add the PDF — Drag the PDF onto the dropzone.
  3. Make your edits — Click to add text/images/signatures, or use the toolbar to redact and reorder.
  4. Download — Click Download — the edited PDF saves to the Files app (Downloads).

Frequently asked questions

Can I really edit a PDF on iPhone for free?

Yes. PDFWix Edit PDF runs in any browser — add or replace text, draw, insert images, redact, sign, all without paying or signing up.

How is this different from Edit on Adobe Acrobat?

Adobe Acrobat does deeper structural editing (re-flow paragraphs, replace embedded fonts, edit form-field properties), which is the right tool for designers and form authors. PDFWix covers the 90% case — fixing typos, adding text/images, redacting and signing — for free, in the browser.

Will edits look correct on every viewer?

Yes. PDFWix writes edits as standard PDF content streams, so every viewer (Edge, Preview, Drive, Acrobat, mobile browsers, printers) renders them identically.

Can I edit a scanned PDF?

Scanned PDFs are images of text. PDFWix lets you draw, add new text boxes, sign and redact on top of the scan, but it cannot rewrite the original image text — that needs OCR first.

Are my edits private?

Yes. Edit PDF runs entirely in your browser. The file and all your changes stay on your device.
