Convert Your .pub File to PNG Images Right in Your Browser
Publisher files don't belong on the modern web, but PNG images do. PubOpener reads your .pub file directly in your browser and exports each page as a PNG — no uploads, no waiting, and no Microsoft Publisher installation required. With Microsoft ending support for Publisher in October 2026, now's a good time to get your old designs into a format anyone can open.
No signup, no limits, no install. Your file never leaves this browser tab — no upload, no server.

PNG is the easiest way to share a Publisher design anywhere text can't go — a Slack message, a product listing page, a printed proof, a slide deck. Instead of asking someone to open a .pub file (which almost nobody can anymore), you hand them a PNG they can view on any phone, laptop, or Chromebook in one click.
PubOpener parses the .pub file format directly in your browser, pulls out the text and embedded images on each page, and renders them into a downloadable PNG. That's a genuine extraction of your file's content — it is not a rendering engine that recreates Microsoft Publisher's exact fonts, spacing, and object positions pixel-for-pixel. If you need a print-ready, visually identical copy, Publisher itself (while it still runs) is the safer bet; PubOpener is built for getting the content out and usable, fast.
That distinction matters for another reason: most "pub to png" sites work by uploading your file to a remote server, converting it there, and emailing or linking back the result. PubOpener never does that. The whole conversion — reading the binary .pub format and writing out PNG images — happens in JavaScript running locally in your browser tab. If your flyer has a client's contact details or your newsletter has an address you'd rather not hand to a stranger's server, that's a real difference, not a marketing line.
There's no file limit, no page limit, and no daily cap — convert one flyer or fifty archived newsletters back to back, for free, with no account. And if PNG isn't the end goal, the same .pub file can be exported as a PDF, searchable HTML, or plain text from the same tool.

Common questions
Do I need Microsoft Publisher installed to convert a .pub file to PNG?
No. PubOpener reads the .pub file format itself, so you can convert and export PNGs even on a machine that has never had Publisher installed.
Is my .pub file uploaded anywhere when I convert it?
No. The entire conversion happens locally in your browser — the file is read and turned into PNGs on your device and is never sent to a server.
Is PubOpener really free, and is there a limit on how many files I can convert?
Yes, it's completely free with no signup, no watermark, and no cap on the number of files or pages you convert.
Will the PNG look exactly like the original Publisher layout?
It extracts the real text and images from your file and lays them out on the page, but it's not a pixel-perfect recreation of Publisher's exact fonts and object positioning — treat it as a faithful export of the content, not a visual clone.
Can I convert a multi-page Publisher document to PNG?
Yes, PubOpener processes every page in the .pub file and gives you a separate PNG for each one.
Does this work on Mac, since Microsoft Publisher is Windows-only?
Yes. Because PubOpener runs entirely in the browser, it works on Mac, Windows, Chromebook, or Linux — no Windows or Publisher required.
