// ABOUT JPEG
JPEG uses lossy compression optimised for photographic content. It discards visual information the human eye is unlikely to notice, achieving compression ratios of 10:1 or higher with minimal perceptible quality loss. JPEG does not support transparency — any alpha channel is flattened against a white background.
// ABOUT WebP
WebP is a modern image format developed by Google that supports both lossy and lossless compression, as well as transparency and animation. Lossless WebP files are typically 25–35% smaller than equivalent PNGs, while lossy WebP achieves similar quality to JPEG at 25–34% smaller file sizes. All major browsers have supported WebP since 2020.
// WHY CONVERT
Converting JPEG to WebP is useful when you need your image in a format suited for web optimisation, responsive images, progressive web apps, and any context where smaller files improve page load times. Note that converting from a lossy source (JPEG) to a lossless target (WebP) preserves the existing quality but cannot recover detail already lost during the original compression. Image Toolz runs the entire conversion directly in your browser. Nothing is uploaded to any server — your files remain completely private on your device. The tool handles images up to 200 MB and most conversions complete in under a second.
// FAQ
What is JPEG?
JPEG is the dominant format for photographs, using lossy compression to achieve small file sizes. It is the standard output format for digital cameras and smartphones.
What is WebP?
WebP is Google's modern format offering both lossy and lossless compression. It consistently outperforms JPEG in file size at comparable quality and is supported by all major browsers.
Will converting JPEG to WebP lose quality?
Minimal additional loss. The WebP output is re-encoded from the JPEG source, which may introduce a small amount of additional compression artifact. At quality 80–90% the difference is usually imperceptible.
Is it safe to convert my files here?
Yes. All conversion runs entirely in your browser. Your images are never uploaded to any server and nothing leaves your device.
