Restart your computer to ensure the system registers the new codec. Step 2: Configure ThumbsPlus File Types
| Issue | Solution | |-------|----------| | No WebP thumbnails | Install WebP codec (e.g., WebP Codec for Windows) or update ThumbsPlus | | “Unknown format” error | Your version is too old – convert externally | | Slow performance | WebP decoding is slower than JPEG; use smaller batch sizes |
If you try to open a WebP file in an older version of ThumbsPlus, you might only see a generic file icon rather than a thumbnail preview. How to Work with WebP in ThumbsPlus (Workarounds)
Historically, ThumbsPlus was built around traditional photography and print formats (JPEG, TIFF, PNG, RAW, BMP, and GIF). Because Cerious Software updates ThumbsPlus on a conservative development cycle, native out-of-the-box support for newer web-centric formats like WebP and AVIF depends heavily on the specific version you are running.

Some legacy versions of ThumbsPlus may require being run in "Windows 95" compatibility mode to function correctly on newer operating systems, though this is primarily for stability rather than format support.
Ultimately, the integration of WebP into ThumbsPlus ensures that one of Windows' most enduring productivity tools remains relevant, proving that even legacy systems can adapt to the high-performance standards of the modern web. Files: Thumb not working with WEBP format #825 - GitHub
This brings us to the central question posed by the keyword "thumbsplus webp." Based on a thorough review of the available documentation and user forums, Restart your computer to ensure the system registers
Do not delete your originals. WebP is superior for web use. Keep two versions: a "master archive" of WebP (smaller storage) and a "converted archive" of JPEG for ThumbsPlus (larger but searchable).

If you are running an older 32-bit version of ThumbsPlus on a 64-bit Windows machine, ensure you install both the 32-bit and 64-bit versions of the WebP WIC codec so the application can access it. Files: Thumb not working with WEBP format #825
Developed by Google in 2010 and open-sourced in 2014, WebP uses both lossy (like JPEG) and lossless (like PNG) compression. It supports transparency (alpha channel) and animation (like GIF). The secret lies in predictive coding—using neighboring pixel blocks to predict values, encoding only the difference.
Show a generic system file icon rather than an image preview.
WebP, developed by Google, offers superior lossless and lossy compression compared to older formats like PNG and JPEG. For a program like ThumbsPlus, which relies on generating high-quality thumbnails for visual browsing, the lack of native support for WebP initially meant that these files would appear as generic icons rather than visible previews. This gap forced long-time users to seek third-party workarounds or wait for updates in an era where software development for the platform had slowed. Evolution and Relaunch
