You are on your phone, you need to black out an SSN or address on a PDF before sending it, and you do not want to install yet another app. Open Safari on your iPhone or iPad, load the free redaction tool, drop in the PDF, draw rectangles with your finger over the sensitive text, and tap Apply. The text is permanently destroyed, the redacted PDF downloads to your Files app, and you can share it immediately.
Redacting a PDF on iPhone — Step by Step
- Open Safari and go to the PDF redaction tool
- Tap the upload area and select your PDF from Files, iCloud, or a recent download
- Draw rectangles with your finger. Touch and drag across the text you want to redact. The crosshair cursor makes it easy to position precisely.
- Navigate pages. Tap the Next/Prev buttons to move between pages
- Tap Apply Redactions. The tool processes the PDF and the redacted version downloads automatically
- Find it in Files. Open the Files app and look in your Downloads folder. Share it from there via email, Messages, AirDrop, or any app.
The whole process works surprisingly well on a phone screen. For documents with small text that requires precise redaction, an iPad provides a larger canvas. But iPhone handles most basic redaction needs.
Why iPad Is Better for Multi-Page Redaction
The larger screen makes a significant difference when you are redacting a 10-page document with scattered sensitive information. On iPad:
- More precise drawing. Your finger covers less of the visible text, so you can see exactly where the redaction box starts and ends.
- Apple Pencil support. If you have an Apple Pencil, the precision is comparable to a mouse. Draw tight redaction boxes around individual words or numbers.
- Split View. Open the redaction tool on one side and your source document or instructions on the other. Useful for redacting based on a checklist.
For quick single-page redactions — blacking out your SSN before texting a document — iPhone is perfectly fine.

iOS has a built-in Markup tool that lets you draw on PDFs. Some people use the pen tool with a black color to "cover" text. This does NOT redact the text. The pen stroke is a visual overlay — the text underneath remains in the PDF and can be extracted.
Even worse: some people take a screenshot of the marked-up PDF and share the screenshot. This works if the screenshot is a raster image, but it loses PDF quality and often misses pages.
The browser redaction tool does it correctly: it flattens each page to an image with the black boxes burned in. No text survives underneath. Use Markup for annotations and notes. Use the redaction tool for permanent content removal.
When You Need to Redact on iPhone
Before texting a document. Someone asks for a copy of your lease, pay stub, or insurance card. Before sharing, black out your SSN, account numbers, or any data the recipient does not need.
Filing documents on the go. Submitting a PDF form that asks for supporting documents? Redact irrelevant information from the attachments before uploading.
Sharing bank statements. Landlords and lenders often ask for bank statements. Redact unrelated transactions, leaving only the relevant income or balance information visible.
Quick privacy cleanup. You saved a PDF with personal information and want to store it in a shared cloud folder. Redact the personal details first so anyone with folder access only sees the public content.

Can I redact a PDF on my iPhone without downloading an app?
Yes. Open Safari and use the browser-based redaction tool. No app download, no account, no subscription.
Does iPhone Markup permanently redact text?
No. iOS Markup draws on top of the PDF but does not remove the underlying text. Anyone can extract the hidden text. Use a dedicated redaction tool for permanent removal.
Where does the redacted PDF save on iPhone?
It downloads to your Files app, typically in the Downloads folder. From there you can share it via any method: email, Messages, AirDrop, or third-party apps.
Can I use Apple Pencil for more precise redaction on iPad?
Yes. Apple Pencil works with the browser-based tool on iPad, giving you precise control over redaction box placement.
