Choose a sensible quality setting
Start with a moderate quality level and inspect edges, text, faces and other high-detail areas. Lower quality usually produces smaller files but can introduce visible artifacts.
The same quality percentage can produce very different results for different images. A flat graphic and a detailed photograph do not compress in the same way. Inspect the areas that matter most to your use case, such as small text in screenshots, sharp product edges or fine facial detail, rather than judging the whole image only from a zoomed-out preview.
Compare before replacing your source
Check the output dimensions and file size against the original JPG. A WebP file can be larger in some cases, especially when the source is already well compressed or contains content that does not benefit from the chosen encoding settings.
Use the WebP copy as the delivery asset while keeping the original file available. This makes future edits, alternate exports and quality comparisons easier.
Confirm destination support
Before replacing a JPG on a third-party website, confirm that the platform, CMS or application accepts WebP. When compatibility is uncertain, keep a JPG fallback or use the format recommended by the destination.
Recommended workflow
- Open Image to WebP and select the source JPG.
- Choose a quality setting and convert it locally.
- Compare the preview and the original/output file sizes.
- Adjust quality when the result is too large or visibly degraded.
- Download the WebP copy and retain the original JPG.
