About the JPG to WEBP Converter

JPG has been the standard for photographic web images for decades, but WEBP outperforms it on almost every metric relevant to the web. Google's WEBP format typically achieves 25–35% smaller file sizes than JPG at comparable visual quality. It also supports transparency (which JPG does not), though converting a JPG to WEBP won't add transparency — the existing solid background is preserved.

When to use this tool

Common use cases

Website image optimisation Replace JPG hero images, banners, and product photos with WEBP to reduce page load time and improve user experience.
Google PageSpeed improvements Google Lighthouse flags JPG images as a performance opportunity — converting to WEBP directly addresses this recommendation.

Tips for best results

  • WEBP is supported by all major modern browsers. If your audience includes users on old browsers, serve WEBP with a JPG fallback using the HTML <picture> element.
  • The quality difference between JPG and WEBP is usually imperceptible to visitors at normal screen sizes — the size reduction is the real benefit.
  • Convert images before uploading to your CMS rather than relying on plugins to do the conversion — you'll get more control over the result.

FAQs

Typically 25–35% smaller at equivalent visual quality. The exact reduction depends on the image content — photos with lots of fine detail see smaller gains; simpler images can see larger reductions.

At high quality settings, the difference is negligible for most images. ConvertFast uses a high quality setting that preserves the look of your original JPG while achieving a meaningful reduction in file size.

WEBP is supported in Chrome, Firefox, Safari 14+, Edge, and Opera — covering the vast majority of web users. Internet Explorer and very old Safari versions do not support it.

No. Converting a JPG to WEBP preserves the original image but cannot create transparency that didn't exist in the source. JPG images have solid backgrounds and the WEBP output will too.

It's good practice to keep the originals as backups. WEBP has limited support in some desktop editing tools, so you may need the JPG for future editing workflows.
