WebP is a next-gen image format developed by Google. Released in 2010, it is now natively supported by all modern browsers: Chrome, Firefox, Safari, and Edge. Simply converting from JPEG to WebP reduces file size by 25-34% on average while maintaining quality.
Image Conversion Caveats
- Lossy→lossless (e.g., JPEG→PNG) cannot recover lost quality
- Re-encoding lossy formats (JPEG→JPEG) degrades quality each time
- Keep RAW/TIFF originals and always convert from them
- Color profile (sRGB/AdobeRGB) shifts can occur during conversion
