JPEG to WEBP Conversion

JPEG files use lossy compression, which means they sacrifice some image quality to achieve smaller file sizes. Every time you edit and save a JPEG, it loses a bit more quality. JPEGs also don't support transparency, so every pixel must have a color value.

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP images are significantly smaller than PNGs and JPEGs, making them ideal for faster website loading times.

Frequently Asked Questions

Why should you convert JPEG to WEBP?

JPEG relies on 1992-era DCT compression optimized for the computing limitations of that time. While revolutionary then, it's now inefficient compared to modern codecs. WebP, released by Google in 2010, uses predictive coding and VP8 video codec technology, achieving 25-34% smaller file sizes than JPEG at equivalent SSIM (Structural Similarity Index) quality scores. Converting to WebP cuts bandwidth usage dramatically - a site serving 100GB monthly of JPEG images drops to 66-75GB with WebP, directly improving Core Web Vitals scores (LCP, CLS) and SEO rankings. Page load times decrease 15-30%, especially critical for mobile users on limited data plans. WebP also adds alpha transparency support that JPEG lacks, replacing both JPEG and PNG in modern web stacks. Supported by all current browsers (Chrome, Firefox, Safari 14+, Edge).
