Introduction
You are putting together a report, a flyer, or a proposal in Microsoft Word, you go to Insert > Pictures, pick a nice image you saved from the web, and Word throws an error or silently does nothing. The file ends in .webp, and Word has no idea what to do with it. This is one of the most common WebP headaches for anyone who works in Office, and it is frustrating because the image looks fine in your browser. Microsoft has added WebP support to newer versions of Office on Windows 11, but plenty of users on older builds, Mac, and Office Online still hit the wall. In this guide we explain why Word rejects WebP and how to get your picture into the document in seconds, with no need to switch computers or upgrade your Office version.
Why This Happens
Microsoft Word relies on the operating system's image codecs to decode inserted pictures. On Windows 10 and earlier, and on older builds of Office, the WebP codec is not installed by default, so Word cannot read the file and either shows an error or refuses to insert anything. Office on Mac has similar gaps depending on the macOS version. The underlying issue is licensing and timing. WebP is a Google format, and Microsoft has been slow to build native support into every Office build, especially the ones bundled with Windows 10 or sold as standalone Office 2019. Newer Microsoft 365 builds on Windows 11 do handle WebP, but you cannot count on it across every device, and collaborators opening your document on their own machines may still see broken images. The fix is to give Word a file format it already trusts, like PNG or JPG, before you try to insert it.
3 Solutions
Solution 1: Convert WebP to PNG before inserting. Run your file through a piczen WebP to PNG converter, then insert the PNG. PNG is lossless and works perfectly in every version of Word, on every operating system, so you never have to worry about compatibility again.
Solution 2: Convert WebP to JPG. For photos where file size matters more than pixel-perfect quality, use a webp to jpg converter instead. You get smaller files with universal Word support, which keeps your document size manageable.
Solution 3: Install the WebP codec on Windows. Add the WebP Codec from the Microsoft Store, restart, and Word will accept WebP natively on that PC. This is a good fix if you insert WebP files often, but it only helps on that one machine and does nothing for collaborators.
Step-by-Step Guide
For the most reliable fix, convert the image before you insert it. Open your browser and load the webp to png converter. Drag your WebP file onto the page or click to browse. The tool processes it in a few seconds. Click Download to save the PNG to your computer. Switch back to Word, click where you want the image, go to Insert > Pictures > This Device, and pick the new PNG file. Word inserts it instantly with no errors. If you are working with a photo and want a smaller file, swap to the webp to jpg converter instead, the steps are identical. For documents with multiple WebP images, convert them all in one batch, download the zip, extract it, and insert each file from there. The whole detour takes about 30 seconds and removes the Word error completely.
Pros and Cons
Converting before you insert is the only approach that works across every version of Word, every operating system, and every Office build, because PNG and JPG are the two formats Word has always understood. The cost is a quick conversion step before you go back to your document. Installing a codec avoids conversion but only helps on that one PC and does nothing for shared documents or collaborators on other devices who may open your file. For most users, the conversion route is the path of least resistance. The inserted image looks identical to the original WebP, so you lose nothing in quality. Keep a webp converter bookmarked so the next time a website hands you a WebP for a document, you can fix it without breaking your workflow. If you work in Office regularly, consider converting WebP files to PNG rather than JPG for documents that will be printed or shared as PDFs. PNG preserves sharp edges on text, screenshots, and diagrams, which means your reports and proposals look crisper when they land on paper or in a client inbox. JPG is fine for photos embedded in casual documents, but its compression artifacts are more visible on line art and small text. For documents with mixed content, you can convert each WebP to the format that suits it, PNG for graphics and JPG for photos, and insert them accordingly. That little extra attention to format pays off in documents that look polished and professional every time. And if you collaborate with others on the same document, using PNG and JPG guarantees that everyone sees the images correctly regardless of their Office version or operating system.
