Publisher to WebP Converter

Publisher to WebP Converter

PUB is Microsoft Publisher's proprietary desktop-publishing format — the layout files behind flyers, newsletters, and brochures. Because it is a binary format that few non-Microsoft apps open, sharing a .pub file rarely works; rasterizing a page to WebP turns the layout into a flat, universally-viewable image that loads anywhere. This converter renders your Publisher page and encodes it as a compact WebP still.

How to Convert Publisher to WebP

1. Upload Your Publisher File: Drag and drop your .pub file onto the page or click "+ Add Files" to browse.
2. Set the Quality Preset: Leave it on "Very High" for a crisp result, or step it down to shrink the file. Keep "Lossless?" on "No" unless you need a pixel-exact copy.
3. Resize If Needed: Use Resolution Percentage, a Preset Resolution, or an exact Width/Height to scale the output for the web.
4. Convert and Download: Click "Convert" and save your WebP. No sign-up, no watermark.

Frequently Asked Questions

Does converting PUB to WebP keep the text editable?

No. Publisher stores your layout as live text, shapes, and image objects, but WebP is a raster image format — the page is flattened into pixels. You can view and share the result anywhere, but you cannot re-edit the wording or move elements afterward. If you need editable or text-selectable output, convert to a document format instead.

My Publisher file has several pages — does this make one WebP per page?

WebP is a single-still image format, so it is best suited to one page at a time. For a multi-page brochure or newsletter where you want every page in one shareable, text-selectable file, convert PUB to PDF instead — PDF keeps all pages together and preserves selectable text, which a flat image cannot.

Can Microsoft Publisher export WebP directly?

No. Publisher's built-in Export and "Change File Type" options cover PNG, JPG, GIF, TIFF, and BMP, but not WebP. That is one reason this converter exists: it rasterizes the layout and encodes WebP in a single step, so you do not have to export a PNG first and re-compress it yourself.

Why does my converted image look different from the Publisher layout?

Some formatting can shift when a proprietary layout is rendered outside Publisher — fonts that are not embedded may be substituted, and complex effects can flatten differently. The closer your design sticks to embedded images and standard fonts, the more faithful the WebP. Raising the Quality Preset preserves more fine detail in text and edges.

Is Microsoft Publisher really being discontinued?

Yes. Microsoft has announced that Publisher will no longer be supported after October 1, 2026, and recommends converting existing .pub files to another format before that date. Rasterizing key pages to WebP (for the web) or PUB to PDF (for archiving) is a practical way to keep your designs viewable once the app is gone.

Should I pick lossy or lossless WebP for a flyer?

For a typical flyer or newsletter page that mixes text and photos, lossy WebP ("Lossless?" set to No) gives the smallest file with little visible loss — Google measures lossy WebP at 25–34% smaller than the equivalent JPEG. Choose lossless only when you need a pixel-exact copy, such as line art or a logo with sharp edges, where compression artifacts would be noticeable. In our testing, a single full-page Publisher flyer rendered to lossy WebP at the Very High preset stayed well under 500 KB while remaining sharp on screen.

Can I shrink the WebP further after converting?

Yes. Lower the Quality Preset or set a "Specific file size" before converting, or run the result through Compress WebP afterward to dial in a target size. If a recipient needs a JPG instead of WebP, convert WebP to JPG once you have the image.
