WebP vs JPG: the numbers
Google's own studies show WebP produces files 25-34% smaller than equivalent JPG files at the same perceptual quality. For a website serving thousands of images, this translates to faster page loads, lower bandwidth costs, and better Core Web Vitals scores. WebP also supports transparency (which JPG doesn't) and animation (like GIF). With universal browser support since 2023, there's no compatibility reason to avoid WebP for web projects.
Browser-based conversion keeps your images private
OnlyFiles converts JPG to WebP using your browser's built-in Canvas API. The conversion runs locally — your images are never uploaded to any server. This is especially relevant for e-commerce product photos, client work, or any images with privacy considerations. The conversion is also faster than server-based tools because there's no upload/download overhead.
When to use this
- Speed up your website by switching to WebP images
- Reduce bandwidth costs for image-heavy pages
- Convert product photos for an online store
Frequently asked questions
How much smaller is WebP compared to JPG?
WebP files are typically 25-34% smaller than equivalent JPG files at the same visual quality. For a website with many images, this can significantly reduce page load times and bandwidth costs.
Is JPG to WebP conversion lossless?
The conversion uses lossy compression (like JPG itself), optimized for the best balance of quality and file size. The quality difference from the original JPG is imperceptible in most cases.
Should I use WebP for all my website images?
For most websites, yes. WebP is supported by all modern browsers, produces smaller files, and Google PageSpeed specifically recommends it. The main exception is if you need to support very old browsers.
