Many websites now use the WebP image format for its superior compression, but users often run into compatibility issues when trying to open or edit these files. Legacy systems, editing tools, and personal workflows frequently rely on JPEG, leading to frustration when downloaded WebP files don't work as expected. Automating the conversion of WebP to JPEG during the download process could solve this without requiring users to manually convert files.

The Automatic Conversion Solution

One way to address this could be a browser extension that detects when a WebP file is being downloaded and converts it to JPEG before saving it locally. The extension might work by:

• Scanning downloaded files for WebP format using file headers or MIME types
• Applying client-side conversion via lightweight libraries like libwebp
• Offering optional settings to adjust JPEG quality or disable conversion for specific sites

For cases where conversion fails, the original WebP file could still be saved with a warning notification. The entire process would happen privately within the user's browser, avoiding any uploads to external servers.

Practical Applications and Advantages

This automated approach could benefit various users:

• Casual users downloading images for personal use who don't have WebP-compatible software
• Professionals needing JPEGs for tools like Photoshop or content management systems
• Organizations with strict file format requirements for their internal systems

Compared to existing solutions like manual converter websites or desktop apps, this approach offers complete automation while maintaining user privacy. The extension could differentiate itself by embedding seamlessly into the browser's download process rather than requiring additional steps.

An initial version might focus on basic conversion with default settings, while future iterations could add features like batch processing or metadata preservation. The concept addresses a growing compatibility gap as more websites adopt WebP while prioritizing user convenience and privacy.
