WebP is widely used on modern websites because it can provide good visual quality with efficient file sizes.
Converting to WebP is most useful when the resulting file is genuinely smaller while still looking appropriate for its intended use.
Why use WebP?
Smaller image downloads can improve page-loading efficiency and reduce bandwidth usage, especially on image-heavy pages.
Should every image become WebP?
No. Some platforms still require JPG or PNG, and already-small images may gain little from conversion.
Converting JPG to WebP
Use the best available JPG source and avoid repeatedly converting already heavily compressed copies.
Converting PNG to WebP
If the PNG contains transparency, make sure the resulting WebP preserves that transparency.
Why WebP can help a website
Images are often among the largest resources downloaded on a page. If converting an image to WebP produces a smaller file while preserving suitable visual quality, visitors may need to download less data.
The benefit becomes more noticeable on pages containing many photographs or large visual elements.
Compare size and appearance together
After conversion, compare the WebP file with the original at the same viewing dimensions. Look at text, edges, gradients and detailed textures.
A smaller file is useful only when the visual result remains appropriate. If artifacts become noticeable, increase the quality or keep the original format.
Check transparency when converting PNG
If the original PNG contains transparent areas, verify that the WebP output preserves them. Test the image over different background colors rather than relying only on the transparency grid.
This is especially important for logos, product cutouts and interface graphics.
Do not convert every image automatically
Some images are already small, while certain external systems may still specifically request JPG or PNG. Converting every asset simply for consistency may create unnecessary work.
Test representative images first before processing a large library.
Keep the original files
WebP can be a useful delivery format without becoming your only source file. Keep original photographs and design assets so you can generate different formats or settings in the future.
This avoids repeatedly converting an already compressed derivative.
Use WebP as a delivery copy when appropriate
You do not need to replace every original JPG or PNG with WebP permanently. A practical workflow is to keep the original design or photograph and use WebP as the optimized copy delivered by the website.
This gives you the performance benefit of a smaller web asset while preserving a source file that can later be exported again at a different quality, size or format.

Choose settings based on where the file will actually be used rather than simply aiming for the smallest size or the highest possible dimensions. Keep your original file, review the processed result and choose a format that suits your final destination.
