Google Slides cannot open PUB files. The conversion always takes two steps. Path 1: export the PUB to PDF with Univik PUB Converter (no Publisher needed) or in Publisher if you still have a working copy. Google Slides cannot open a PDF, so turn each page into a PNG picture (the converter can write PNG directly) and insert one picture on each slide. The layout stays as an image. To see each page before rebuilding it as Google Slides, open the PUB file in the free Univik PUB File Viewer on Windows. Path 2: build a PPTX first (convert the PUB to Word, then move the content into PowerPoint), upload the PPTX to Google Drive and open it in Slides. This gives editable text but lower layout fidelity. Path 1 is better for preserving visual layout. Path 2 is better when you need the slide content to remain editable.
Update, 1 October 2026: Publisher has left Microsoft 365
Publisher has gone from Microsoft 365. To do the “export to PDF in Publisher” step today, you need a perpetual 2021, 2019 or 2016 licence, or a Microsoft 365 copy that Microsoft has not removed yet. Your PUB files are not deleted. Univik PUB File Converter turns them into PDF files without Publisher, ready to upload to Google Drive for Path 1 below.
No Direct PUB to Google Slides Path
Google Slides has no PUB import. You cannot upload a PUB file to Google Drive and open it in Slides. If you only need to check what is inside one before converting, you can Open PUB files Online in your browser first. The format is not recognised, so Google Drive displays PUB files as a download-only generic file with no preview and no open option.
Every path from PUB to Google Slides goes through an intermediate format. The choice of intermediate format determines what you get at the end: a visually accurate but non-editable result or a more editable result with less layout fidelity.
“Slides are tested the same way as every other target in our Publisher work: convert a batch, open the deck and compare graphics and text formatting slide by slide against the PUB source.”

When Google Slides Is the Right Destination
Google Slides is a good Publisher replacement for specific use cases and a poor fit for others. The question to ask first: was the Publisher document slide-based or document-based?
Good fit for Slides
- Single-page or two-page visual layouts (posters, flyers, one-pagers)
- Presentations built in Publisher that need to move to a collaborative platform
- Content that will be presented on screen or projected
- Teams using Google Workspace who want to avoid a separate design tool
- Designs that need real-time collaboration across a team
Poor fit for Slides
- Multi-page newsletters with flowing text across pages
- Brochures with complex column layouts
- Print-ready documents requiring bleed and CMYK
- Long-form catalogues or publications
- Documents where typography precision matters
If the Publisher document is a multi-page newsletter or brochure with flowing text, Google Docs is likely the better destination. See our PUB document to Google Docs guide for that workflow.
Path 1: PUB to PDF, Then PDF to Slides
This path produces the best visual result. The layout is preserved as it appears in Publisher. The trade-off is that text in the resulting slides is not directly editable, because it is part of the image layer from the PDF rendering.
Export the PUB to PDF. If you still have a working copy of Publisher, open the file and go to File then Export then Create PDF/XPS. Click Create PDF/XPS, choose a location and click Publish. If you no longer have Publisher, which is now the case for most Microsoft 365 users, use Univik PUB Converter to convert PUB to PDF in bulk on Windows without Publisher installed.
Turn each page into a picture. Google Slides cannot open a PDF by itself. If you made a PDF, save each page as a PNG with the PDF tool you already use. Better still, pick PNG as the output in Univik PUB Converter and it writes one picture for each page, so you can skip the PDF.
Place the pictures in Google Slides. Open a blank presentation at slides.google.com. On each slide click Insert then Image then Upload from computer and pick the picture for that page. The slides look like the original pages. The text is part of the picture, so it cannot be selected or edited in Slides.
Add editable elements on top if needed. Insert new text boxes in Slides for any text that needs to be updated going forward. The page picture serves as the visual background while new Slides text boxes hold the editable content. Delete the page picture from any slides where the editable rebuild is complete.
Path 2: PUB to PPTX, Then PPTX to Slides
This path produces editable text in Google Slides but with lower layout fidelity. Choose it when the words in your Publisher file are more important than how the page looks.
Convert the PUB to PPTX. Use the two-step PUB to PowerPoint path described in our PUB to PowerPoint guide: PowerPoint cannot open a PUB file or a PDF, so this takes a middle step. Convert the PUB to Word DOCX with Univik PUB Converter (or save it from Publisher if you still have a working copy). Then copy the text and pictures into a PowerPoint deck and save it as PPTX.
Upload the PPTX to Google Drive. Go to drive.google.com and click New then File upload. Select the PPTX file. Google Drive uploads and processes it.
Open the PPTX in Google Slides. Right-click the file in Google Drive and select Open with then Google Slides. Slides converts the PPTX to its native format. Text is editable. Images and layout are partially preserved depending on how faithfully the PUB-to-PPTX step performed.
Review and adjust. Check text positioning, font rendering and image placement. Google Slides may substitute fonts not available in its library. Complex layout elements from the original PUB may need manual repositioning.
What Survives Each Path
| Element | Path 1: PDF to Slides | Path 2: PPTX to Slides |
|---|---|---|
| Visual layout | ✅ Preserved as image | ⚠️ Partial (varies by complexity) |
| Images | ✅ Preserved in image layer | ⚠️ Usually preserved |
| Editable text in Slides | ❌ Text is part of image | ✅ Editable text boxes |
| Custom fonts | ✅ Embedded in image | ⚠️ Slides substitutes unavailable fonts |
| Slide-per-page | ⚠️ One picture per slide, placed by you | ✅ Automatic from PPTX structure |
| Collaboration in Google Workspace | ✅ Full Google Slides sharing | ✅ Full Google Slides sharing |
| Publisher required | Only if you export from Publisher (needs a working copy). Not needed with the batch converter | Only if you export from Publisher (needs a working copy). Not needed with the batch converter |
Google Slides vs Google Docs: Which One?
If you are migrating Publisher content to Google Workspace and are unsure whether Slides or Docs is the right destination, the deciding factor is whether the Publisher document is layout-driven or text-driven.
| Publisher Document Type | Better Destination |
|---|---|
| Flyers, posters, one-page visual layouts | Google Slides |
| Presentations originally built in Publisher | Google Slides |
| Newsletters with continuous text | Google Docs |
| Brochures with multi-column text flow | Google Docs |
| Documents intended for editing and updating | Google Docs |
| Documents intended for screen presentation | Google Slides |

Using Slides as an Ongoing Publisher Replacement
For organisations moving to Google Workspace, Slides works as a Publisher replacement for visual and presentation-style content. For new content created directly in Slides:
Set slide dimensions to match your print format. In Slides, go to File then Page setup then Custom. Enter the dimensions of your document in centimetres or inches (A4, US Letter, DL flyer or custom). This makes sure the design exports correctly to PDF for printing.
Use Slides themes for brand consistency. Create a custom Slides theme with your brand fonts and colours. Apply it to all new documents so the visual style stays consistent without manually setting colours each time.
Export to PDF for printing. File then Download then PDF Document produces a print-ready PDF from the Slides layout. For basic print materials, quality is adequate. For professional commercial print with CMYK requirements, Slides does not meet professional print standards.
Frequently Asked Questions
Can Google Slides open a PUB file directly?
No. Google Slides and Google Drive do not recognise the PUB format. PUB files uploaded to Google Drive appear as generic download-only files with no preview and no open option. The conversion to Slides always requires an intermediate step: either a PDF or a PPTX made from the original PUB file.
Which is better for converting Publisher to Google Slides: via PDF or via PPTX?
Via PDF if you want to preserve the visual layout: the slide looks like the Publisher document, but text is not editable in Slides. Via PPTX if you need editable text in the resulting slides: text is selectable and editable, but layout fidelity is lower. For most presentation and display use cases, the PDF path produces a more polished result. For content that a team needs to update regularly, the PPTX path gives them editable access.
Can I batch-convert PUB files to Google Slides?
Not directly in Google Slides. The practical batch approach is to convert all PUB files to PNG in bulk using Univik PUB Converter on Windows, which writes one picture for each page. Then insert those pictures into Slides one presentation at a time. For large archives, prioritise the most actively used documents for the Slides conversion and store the remainder as PDF in Drive for reference.
Does Google Slides support the fonts used in Publisher?
Google Slides uses Google Fonts. If the Publisher document used fonts not available in the Google Fonts library, Slides substitutes the closest available font in the PPTX-to-Slides path. In the PDF-to-Slides path, the original fonts are preserved as they are baked into the page picture. For brand documents requiring specific fonts, the PDF path is safer for font fidelity.
Is Google Slides a good replacement for Microsoft Publisher?
For single-page visual content and presentation-style layouts, yes, with a reasonable trade-off. For complex multi-page publications with flowing text, columns and print-ready specifications, no. Google Slides is a collaborative presentation tool, not a desktop publishing application. For the closest feature replacement to Publisher within Google Workspace, Google Docs handles document-style Publisher output better than Slides does for most use cases.
The Short Version
Converting Publisher files to Google Slides takes two steps regardless of which path you use. PDF to Slides gives you the visual layout preserved, but text is not editable. PPTX to Slides gives you editable text with lower fidelity. The right path depends on whether the slides need to be updated or only displayed.
For Publisher documents that are more document than presentation (newsletters, brochures and multi-column layouts), Google Docs is a better destination than Slides. Slides is the right choice for visual and presentation-style content that belongs on a slide canvas rather than a scrolling page.
Is the Publisher content you are migrating primarily visual and presentation-based or primarily text-based with layout complexity? That distinction determines whether Slides or Docs is the right Google Workspace destination.
