Open a .pub File on iPhone or iPad in Safari
Got a Microsoft Publisher (.pub) attachment on your iPhone and no way to open it? Apple never shipped a Publisher app for iOS, and Microsoft is ending Publisher support on October 13, 2026, so this problem is only getting more common. PubOpener runs right inside Safari on your phone, reading the .pub file's text and images so you can view and export them — it's an honest extraction, not a pixel-identical copy of the original Publisher layout.
No signup, no limits, no install. Your file never leaves this browser tab — no upload, no server.
Verify: how it works ↗
There is no Microsoft Publisher app for iPhone or iPad, and there never has been — Publisher is a Windows-only desktop program. The App Store has a handful of paid "PUB Reader" style apps that promise viewing and conversion, but you don't need to buy one just to see what's inside a file someone emailed you.
PubOpener works differently: it's a website, not an app, so there's nothing to install or purchase. Open Safari on your iPhone, go to pubopener.pro, and pick the .pub file from your Files app, iCloud Drive, or straight out of a Mail or Messages attachment using the share sheet's "Save to Files" option. The page reads the file using JavaScript running locally in your browser — your .pub never leaves the phone or gets uploaded to a server, which matters if the file has a client name, invoice, or event flyer on it.
Once it's processed, you'll see the extracted text and any embedded images from the publication, and you can export the result as a PDF, PNG, HTML page, or plain text file — all saved back to your iPhone's Files app or shared straight from Safari. This is the fastest way to actually read a Publisher flyer, newsletter, or brochure on iOS without a computer nearby.
One honest caveat: complex Publisher layouts with precise text wrapping around shapes, multiple linked text boxes, or exact font substitutions may not come out looking identical to the original — PubOpener extracts the content faithfully rather than recreating Publisher's rendering engine pixel-for-pixel. For reading the text and pulling out images and photos, it works well; for a design proof you're sending to a print shop, open the original in Publisher on a Windows PC first if you can.

Common questions
Is there a Microsoft Publisher app for iPhone or iPad?
No. Microsoft has never released Publisher for iOS — it's Windows-only. Any "Publisher viewer" app in the App Store is a third-party tool, not made by Microsoft, and most charge a fee to unlock full viewing or export.
Is PubOpener really free to use on iPhone?
Yes. There's no cost, no account, no file limit, and no watermark. It's a free web tool, not a trial version of a paid app — you use it in Safari the same way you'd visit any website.
Is my .pub file uploaded anywhere when I use PubOpener on my phone?
No. The file is parsed locally by JavaScript running in your iPhone's browser. Nothing is sent to a server, so a Publisher file with private or client content stays on your device the whole time.
Do I need Microsoft Publisher installed to open a .pub file on iPhone?
No. Publisher isn't available for iOS at all, so PubOpener is built specifically for people who need to view a .pub file without owning a copy of Publisher on any device.
How do I convert a .pub file to PDF on my iPhone?
Open Safari, go to pubopener.pro, choose the .pub file from Files, iCloud Drive, or an email attachment, then use the export option to save it as a PDF directly to your iPhone.
Is it safe to open a .pub file attachment on iPhone?
Treat unexpected attachments from unknown senders with the same caution as any file type. Because PubOpener processes the file entirely in-browser rather than uploading it, it doesn't add a third party into the chain — you're just reading the file's content locally.
