Korva vs Scribus: Which Opens Your .pub Files?

If your goal is to open old .pub files, Korva beats Scribus: Korva reads Publisher files directly and exports a print-ready PDF, while Scribus has only a fragile, often-broken import filter and a steep learning curve. The flip side is real, though: Scribus is free and does proper CMYK prepress, which Korva does not. This is a head-to-head on which one fits your actual job.

Microsoft retires Publisher on October 1, 2026. After that date it leaves Microsoft 365 and stops getting fixes, and Microsoft’s own advice is to convert your files to PDF for viewing and Word for editing first, even though Word has no .pub import filter at all. So people are scrambling for a replacement, and two names that keep coming up are Korva and Scribus. They look similar from a distance, two desktop publishing apps, but they solve genuinely different problems. Let’s sort out which is which.

One note up front: “Microsoft Publisher” and “Microsoft” are trademarks of Microsoft Corporation, and “Scribus” is a trademark of its respective owner. Korva is an independent product and is not affiliated with, sponsored by, or endorsed by either.

The one question that decides it

Before any feature list, ask yourself one thing: do you already have .pub files you need to open, or are you starting fresh?

That single answer flips the recommendation. If you have a folder of legacy Publisher documents, bulletins, flyers, certificates, a newsletter you’ve run for years, your first need is reading .pub at all. If you’re starting from a blank page with no old files to rescue, that question disappears and output quality takes the lead instead. Keep your situation in mind as we go, because Korva and Scribus land on opposite sides of it.

Scribus: free, powerful, and built for the print shop

Let me give Scribus its due first, because it earns it. Scribus is a mature open-source desktop publishing application, currently at version 1.6.6 (released April 2026), and it is genuinely capable. It uses a frame-based layout workflow with master pages, styles, and advanced typography. The part that matters most: it does real commercial print production. Full CMYK colour, spot colours, ICC colour management, colour separations, and PDF/X export (including PDF/X-3 and PDF/X-4). Hand a job to a print house that demands proper prepress files with bleed and crop marks, and Scribus delivers, for free, with no subscription attached. Not many tools can say that.

It runs on Windows, macOS, and Linux, it’s licensed under the GNU GPL (with parts under the LGPL), and it has an active community plus a built-in Python scripting engine. For someone making new documents who needs serious print output and doesn’t mind learning a pro tool, Scribus is hard to beat on price.

So where’s the catch? Two of them, and both matter a lot if you’re coming from Publisher.

Catch one: it won’t reliably open your .pub files

This is the big one. Scribus did add an experimental Microsoft Publisher import filter back in the 1.5 development series, so on paper “Scribus opens .pub” is technically true. In practice, as of 2026, that support is fragile. Users regularly report that the .pub option is missing or greyed out in the import dialog, that imported files won’t edit afterward, or that the import simply fails on real-world documents. The Scribus community itself often advises routing the file through LibreOffice first and importing the result, which tells you how shaky the direct path is. If your whole reason for switching is rescuing old Publisher files, leaning on Scribus’s importer is a gamble I wouldn’t take.

Catch two: the learning curve is steep

Scribus is a professional layout application, and it expects you to think like one, in frames, styles, and colour profiles. People arriving from Publisher’s friendly ribbon tend to bounce off it on the first try. Give it a weekend and it clicks, but it is not a ten-minute tool. If you just want your flyer back so you can fix a date and reprint it, that ramp is a lot of overhead.

Korva: built to open .pub, and not much harder than Publisher

Korva was built for exactly this moment, Publisher’s shutdown. It’s a cross-platform desktop publisher that opens legacy .pub files, lifts the content onto a real editable page, and exports a print-ready PDF.

The headline difference is the import. The .pub format is a proprietary binary CFB/OLE2 compound file, and its page-geometry stream is undocumented, which is precisely why almost nothing reproduces a Publisher layout perfectly. Korva’s approach is honest about that. It pulls the text out (accented characters preserved) and every embedded image, then drops them onto a clean canvas you tidy up. Photos come through embedded losslessly, and accented text survives intact. Think “open and fix” rather than a pixel-perfect clone: you get your content back, nudge the positions, and move on. That is a far cry from Scribus, where for most files you’d be rebuilding the page from scratch.

Everything runs on your own computer. The desktop app works fully offline, with no account, sign-in or telemetry, and your files never leave the machine. The free tier opens any .pub, edits the recovered layout and exports PDF. A one-time US$49 Korva Pro licence adds editable .kva saves, master pages and mail merge on one movable computer. Activate it online once, then work offline with no subscription.

There’s also a wrinkle Scribus can’t match on ease of entry. Korva’s free desktop tier opens any .pub, lets you tidy the recovered layout and exports PDF without payment. It processes the file entirely on your own machine, so nothing is uploaded. There is no native iOS or Android app; Korva is a desktop app for Windows, macOS and Linux.

The editor itself stays close to what a Publisher user expects: a familiar ribbon-style interface, drag-to-move with snapping guides, resize handles, in-place text editing, picture pan and zoom, multi-select with align and distribute, rotation, a layers panel, find and replace, and undo. There’s mail merge from a .csv for business cards, certificates, and address labels, plus master pages and built-in templates.

Now the honest limit, stated plainly: Korva exports RGB PDFs, not prepress CMYK. No CMYK separations, no bleed, no crop marks, no spot colours, no PDF/X. That’s fine for digital sharing and for most office, community, church, and short-run printing. But if you’re sending a glossy catalogue to a commercial offset press that demands CMYK, that’s Scribus’s job, not Korva’s.

Korva vs Scribus: the comparison table

So which should you use?

Here’s how I’d sort it, honestly.

• You have .pub files to rescue: Start with Korva. The free reader opens them and lets you convert each one to a PDF before you decide anything else, no account needed. Scribus’s importer is too unreliable to trust for this.
• You’re sending jobs to a commercial offset press with CMYK and crop marks: Scribus, no contest. It does real prepress, for free. Just don’t expect it to open your Publisher files.
• You want a gentle tool that feels like Publisher: Korva, by a wide margin. The ribbon UI and “open and fix” workflow are far closer to what you already know than Scribus’s frame-based, profile-heavy interface.
• You want both: Plenty of people do exactly this. Use Korva to recover and maintain the old work, then Scribus for any new piece headed to a commercial press. The two barely overlap, so they sit side by side without conflict.

The practical path I’d suggest: open your .pub files in Korva first, get the content out and exported safely, then decide whether your future work actually needs Scribus-grade CMYK printing or whether Korva’s RGB output already covers it. For most church, school, office, and community jobs, RGB is plenty. For a print-house catalogue, it isn’t. If you want the wider field, our roundup of the best Microsoft Publisher alternatives lines up Affinity, Canva, and Microsoft 365 too, and our three-way comparison with LibreOffice Draw digs deeper into the free options.

The bottom line

Scribus and Korva aren’t really rivals so much as tools for different jobs. Scribus is the free prepress workhorse for new commercial print. Korva is the one built to open the .pub files you already have, simply, offline, for a single payment. If you’re reading this because of Publisher’s shutdown, that’s almost certainly the box you’re in.

The fastest way to know is to test it on your own files. Download Korva and grab the free Reader & Converter tier, open one of your real .pub documents, no account required, and see exactly what survives before you commit to anything.
