Converting JPG to WebP: what to know
When you need it
WebP photos are usually noticeably smaller than JPGs that look the same, which speeds up pages and cuts bandwidth. Converting your JPGs is one of the simplest improvements for a blog, an online shop or a portfolio.
What to expect
The WebP is typically lighter than the original JPG. Because the JPG was already compressed, conversion can't add detail that isn't there, and a very low quality setting adds visible artefacts on top of the existing ones.
Tip: Start with High (85) under Advanced options and compare. Keep your JPGs for email and older software, which may not open WebP.

What is JPG?
JPG (JPEG) is the standard format for photos. Its lossy compression makes images much smaller with little visible difference, and every device, browser and program opens it. It does not support transparency, and repeated re-saving gradually degrades quality.
What is WebP?
WebP is Google's modern image format for the web. It supports lossy and lossless compression, transparency and animation, and usually produces smaller files than JPG or PNG. All current browsers show it, but some older programs and apps cannot open it.
Tips for converting JPG to WebP
- Transparent backgrounds are only kept in formats that support them (PNG, WebP, AVIF); JPG fills them with white.
- For photos, lossy formats keep files small; for logos, screenshots and text, lossless PNG stays sharper.
- Converting an already compressed JPG does not add detail — start from the highest-quality original you have.
- If the image is for a website, a modern format such as WebP or AVIF usually loads faster than JPG or PNG.
