Webp - Thumbsplus
Import new images, rename them according to your convention, and convert them to WebP simultaneously.
For advanced users, here is a Python script that acts as a bridge. It scans a ThumbsPlus database (SQLite) for WebP files and generates proxy JPEGs.
Once ThumbsPlus recognizes your WebP images via the system codec, you can utilize its legendary batch processing tool to convert web images into more versatile offline formats. Select the WebP images you wish to convert. Go to > Batch Process (or press F12 ). Set your desired Output Format (e.g., JPEG or PNG). Specify your target output directory. Click Start to execute the conversion seamlessly. Troubleshooting Common Issues
WebP lossy images are negligibly smaller compared to JPEGs—often 25% to 34% smaller at equivalent structural similarity (SSIM) quality. thumbsplus webp
ThumbsPlus remains a powerful and efficient tool for managing traditional image archives. Its speed, database structure, and unmatched batch processing capabilities are still relevant for many workflows. However, the digital landscape has evolved. Google's WebP format is no longer an emerging technology; it is the present standard for efficient image delivery on the web.
Around 2020, the developer, Cerious Software, announced that was in the works. This update was specifically promised to include support for modern formats, including HEIC (Apple’s format) and WebP , alongside necessary bug fixes. However, the project appears to have ground to a halt. The last official communication cited the COVID-19 pandemic as a reason for shifting to work-from-home, but years passed without further progress or status reports from the company.
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). Import new images, rename them according to your

| ThumbsPlus Version | WebP Thumbnails | WebP Viewing | Batch Convert WebP | |--------------------|----------------|--------------|--------------------| | v10 or older | No | No | No | | v11 + Windows WebP codec | Sometimes | Limited | No | | v11 + external converter | No | Via “Open With” | No (manual pre-conversion needed) | Once ThumbsPlus recognizes your WebP images via the
Given these benefits, WebP has become widely adopted across the web and is natively supported by all modern browsers.
Adobe products have supported WebP since 2022.
WebP, developed by Google, has seen widespread adoption due to its ability to provide high-quality visuals at significantly smaller file sizes compared to traditional JPEG or PNG formats.
