Image Format Converter

📖 Description

1. Why is Image Format Conversion Needed?

Different usage scenarios have vastly different technical requirements for image formats:

• Web Performance Optimization: Converting bulky $JPG$ files to the modern $WebP$ format can reduce traffic overhead by $30% \sim 70%$ while maintaining the same visual quality.
• Preserving Transparency: Converting regular photos to $PNG$ format for tasks like background removal or overlaying on complex backgrounds.
• Meeting System Restrictions: Some government and banking systems only support specific formats (e.g., $JPG$). Conversion allows you to easily bypass upload restrictions.
• Animation Extraction: Extracting key frames from $GIF$s into static images, or combining static image sequences into a new format.

2. Core Features Explained

This site's conversion tool utilizes multi-engine parallel processing technology to ensure the conversion process is both fast and stable:

A. Extensive Format Coverage

• Common Formats: $JPG/JPEG, PNG, GIF, BMP, TIFF$.
• Modern Web Standards: Full support for $WebP$ and $AVIF$ (high compression ratio, high performance).
• Vector to Raster: Instantly render $SVG$ vector graphics into pixel images of specified dimensions.

B. Intelligent Parameter Presets

• Quality Adjustment: When converting to $JPG/WebP$, manually set the compression quality to precisely control file size.
• Transparent Background Preservation: When converting between $PNG$ and $WebP$, the Alpha transparency channel is perfectly preserved without generating black borders or white backgrounds.
• Batch Parallel Conversion: Supports dragging and dropping multiple files of different formats at once, with one-click unified output to the target format.

C. Privacy Protection (Local Processing)

• In-Browser Conversion: The core conversion logic is completed locally in your browser. Images do not need to be uploaded to our servers. This not only means conversion speed is not limited by network speed but also fundamentally ensures the security of sensitive images.
