The following essay examines the intersection of a legacy software powerhouse, ThumbsPlus, and the modern web standard, WebP.

The Digital Archivist’s Dilemma: ThumbsPlus and the WebP Revolution

For over three decades, ThumbsPlus has served as a cornerstone for photographers and digital archivists managing massive media libraries. Developed by Cerious Software, it became a pioneer in database-driven image management, offering robust batch processing and metadata tools that many modern competitors still struggle to match. However, as the digital landscape shifted toward the highly efficient WebP format, this legacy giant faced a significant technological hurdle. A Legacy of Versatility

At its peak, ThumbsPlus was renowned for its exhaustive format support, handling everything from standard JPEGs to obscure scientific and proprietary RAW formats. Its core strength—the ability to catalog thousands of images in a searchable SQL-driven database—made it indispensable for professional workflows. Yet, the rapid adoption of WebP by web browsers and developers introduced a format that older iterations of the software were not natively built to recognize. The WebP Challenge

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

The story of ThumbsPlus and WebP is one of adaptation. Recent efforts to relaunch and update the software have focused on bridging these modern gaps. As newer versions and service packs were released, the goal was to integrate the necessary libraries to handle WebP's unique encoding. This evolution represents more than just a software update; it is a vital bridge for archivists who need to manage modern web assets alongside decades of historical photography within a single, familiar interface.

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

ThumbsPlus and the WebP Challenge: How to Manage Next-Gen Images

If you’ve been a long-time user of ThumbsPlus by Cerious Software, you know it’s a powerhouse for organizing massive libraries of photos, fonts, and vector files. However, as the web moves toward the WebP format for its superior compression and quality, many users find themselves in a bit of a bind.

Here is what you need to know about using WebP files with ThumbsPlus and how to keep your workflow smooth. Does ThumbsPlus Support WebP?

As of current versions, such as ThumbsPlus 10, native support for the WebP format is not explicitly listed in the standard supported formats like JPEG, PNG, or TIFF. While the software supports over a hundred file types—including diverse RAW formats through Pro plugins—WebP often requires a workaround because it is a relatively newer "next-gen" format compared to the legacy codebases of many classic image managers. Why WebP Matters for Your Collection

Smaller File Sizes: WebP files are often 25-34% smaller than comparable JPEGs without losing visible quality. thumbsplus webp

Transparency and Animation: Unlike JPEG, WebP supports alpha channels (transparency) and can even replace bulky GIFs.

SEO Performance: If you are using the ThumbsPlus Web Page Wizard to build online galleries, WebP is the format Google recommends for better search rankings and faster load times. Workarounds for ThumbsPlus Users

If your ThumbsPlus isn't generating thumbnails for your WebP images, here are a few ways to bridge the gap:

System-Wide WebP Codecs: Ensure your Windows OS has the WebP Video Extensions installed from the Microsoft Store. Sometimes, third-party apps like ThumbsPlus can leverage system codecs to "see" file types they don't natively handle.

External Batch Conversion: Use the batch processing features within ThumbsPlus to convert existing archives to WebP if you have a compatible plugin, or use a tool like XnConvert to turn WebP files into high-quality JPEGs that ThumbsPlus can catalog effortlessly.

Launch External Editors: You can configure ThumbsPlus to launch external editors for specific file types. By linking WebP files to a modern browser or a free editor like Paint.NET, you can still view the full-resolution files even if the thumbnail preview is a generic icon.

While ThumbsPlus is a long-standing image management and thumbnailing application, its support for modern formats like WebP can be a point of confusion for users of its older versions. WebP in ThumbsPlus

Modern versions of ThumbsPlus, specifically from Version 10 onwards, have integrated support for a wider array of graphics formats to keep pace with web standards.

Viewing and Managing: Users on current versions can typically browse, view, and generate thumbnails for WebP files just as they would for standard JPEGs or PNGs.

WebP Advantages: Integrating WebP into your workflow allows you to maintain high-quality imagery with file sizes that are often 25-34% smaller than JPEGs, which is a primary reason for the format's popularity among webmasters using Google for Developers resources.

Legacy Version Workarounds: If you are using an older version (e.g., Version 7 or 8) that does not natively recognize WebP, you might need to use external plugins or converters. Some users on the VirtueMart Forum have noted that while thumbnail creation for WebP can sometimes be "enabled" via manual helper file modifications in certain environments, it is generally safer to upgrade to a version that supports the format natively. Common Issues

Missing Thumbnails: If WebP thumbnails are not appearing, it may be due to the software's underlying image library lacking encoding support, a known issue in some development frameworks discussed on GitHub.

Compatibility: 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.

For those moving away from ThumbsPlus to more modern workflows, it is worth noting that the software's database export feature can help preserve your metadata, such as keywords and file names, during a transition. Files: Thumb not working with WEBP format #825 - GitHub

The Modern Image Management Dilemma: Navigating WebP with ThumbsPlus

For decades, Cerious Software ThumbsPlus has been a stalwart for photographers and designers, prized for its robust database-driven approach to image cataloging. However, the rise of Google’s WebP format—designed to replace JPEGs and PNGs with superior compression—has introduced new hurdles for users of "retro" management tools. The WebP Challenge in ThumbsPlus Lossy and lossless WebP decoding and encoding Batch

As of recent updates, native support for WebP remains a complex topic for ThumbsPlus users. While the software excels at handling over 100 legacy formats like JPEG 2000, TIFF, and RAW, the lack of built-in WebP decoding in older versions means these files often appear as broken icons rather than viewable thumbnails.

Format Limitations: ThumbsPlus relies on specific image libraries that may not natively include the libwebp encoding required for this "next-gen" format.

The Version Gap: While ThumbsPlus Version 10 introduced massive database scaling (up to 5 million thumbnails), many users find they still need workarounds for modern web-centric formats. Solutions and Workarounds

If you are managing a massive archive and need WebP visibility, you don't necessarily have to abandon your database.

For long-time users of ThumbsPlus, the classic image database and thumbnailing software, the rise of modern web formats like WebP has presented a significant challenge. While newer image formats offer better compression and quality, older software often struggles to keep up with native support. The Challenge: ThumbsPlus and Modern WebP Files

ThumbsPlus is a powerful tool for organizing thousands of images, but its development cycle has slowed in recent years. As of the latest stable versions (like Version 10), native WebP support is often missing or inconsistent. Users frequently find that while their JPEG and PNG files display perfectly, WebP files appear as generic icons or cannot be viewed within the application at all.

This gap is particularly frustrating because WebP is now natively supported by almost 96% of modern web browsers. It has become the standard for web performance, offering lossy and lossless compression that outperforms traditional formats. Why Support is Slow to Arrive

The technical hurdle often lies in the underlying image libraries used by the software. Many older Windows-based cataloging tools rely on libraries that do not have native WebP encoding or decoding built-in. For ThumbsPlus to fully support WebP, its developers would need to integrate modern codecs, a task that has been delayed according to user reports on the software’s future. Solutions and Workarounds for ThumbsPlus Users

If you need to manage WebP files using ThumbsPlus, here are the most effective workarounds: Thumbsplus Webp [verified]

Here’s a detailed feature concept for ThumbsPlus (a popular image management and batch processing tool) that adds full WebP support across its core functionality.

Scenario A: Convert a Folder of JPEGs to WebP (Saving Space)

You have 5,000 high-res JPEGs taking up 2GB of space. WebP can shrink that to 500MB.

  1. In ThumbsPlus, select all JPEG thumbnails.
  2. Right-click > Batch Convert.
  3. In the "Save as type" dropdown, look for WebP File Format (*.webp).
    • If missing: You need the external plugin (see Part 4 below).
  4. Set your quality slider:
    • 80-85% (Visual parity with JPEG quality 90, but 25-35% smaller)
    • Lossless mode: Check this if converting PNGs with sharp text/logo edges.
  5. Choose your output directory.
  6. Click Start. ThumbsPlus will decode the JPEG and re-encode as WebP.

Step 2: Verify File Association

Ensure .webp files are associated with an image viewer (like Photos or IrfanView) that ThumbsPlus can "ask" for data. Right-click a WebP file > Properties > Opens with > Change to "Windows Photo Viewer" or "Photos."

Part 9: A Script to Automate ThumbsPlus WebP Management

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.

import sqlite3
import os
import subprocess

Real-World Impact


    

  • Web Performance: A website swapping JPEGs for WebP reduces page load time by 30% on average.
    • 

  • Storage: A 5MB JPEG becomes a 3.5MB WebP without visible quality loss.
    • 

  • SEO: Search engines, especially Google, prioritize fast-loading images. WebP is a ranking signal.
    • 



Using Freeware: FastStone Image Viewer


    

  • Open FastStone.
    • 

  • Browse to your WebP folder.
    • 

  • Select all > Batch Convert.
    • 

  • Output format: PNG (preserves transparency) or JPEG (smaller).
    • 

  • Ensure "Keep original folder structure" is checked.
    • 



Warning: 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).


Troubleshooting Common Issues


Even with codecs installed, you may encounter hiccups. Here is a checklist for troubleshooting:


    

  • Blank Thumbnails: If you see generic icons, the codec isn't initializing. Try running ThumbsPlus as Administrator once to force the registration of new libraries.
    • 

  • Crash on Scan: If ThumbsPlus crashes while scanning a folder with mixed files, it is likely encountering a corrupted WebP file. Try scanning a folder with only WebP files to isolate the issue.
    • 

  • 32-bit vs 64-bit: Remember that the standard ThumbsPlus version is 32-bit. If you install a 64-bit WebP codec, ThumbsPlus might not "see" it. Ensure you install the 32-bit compatible version of the codec if available, or the standard x86 version.
    • 



2. Enabling WebP Thumbnails


If WebP files show as generic icons:


    

  1. Go to Tools > Options > File Types.
    2. 

  2. Scroll to WebP.
    3. 

  3. Check Enable and Show thumbnails.
    4. 

  4. Click Rebuild Thumbnails for selected folders.
    5. 



Find all WebP files


cursor.execute("SELECT filename, path FROM images WHERE extension = 'webp'")
rows = cursor.fetchall()


for filename, path in rows:
full_webp = os.path.join(path, filename)
proxy_jpg = os.path.join(proxy_folder, filename.replace('.webp', '.jpg'))


# Use ImageMagick to convert
if not os.path.exists(proxy_jpg):
    subprocess.run(['magick', full_webp, '-quality', '90', proxy_jpg])
# Update ThumbsPlus to point to proxy (requires DB write)
cursor.execute("UPDATE images SET proxy_path = ? WHERE filename = ?", (proxy_jpg, filename))



conn.commit()
conn.close()
