Creating a WebP copy gives you another delivery option for a JPEG photograph. Whether that copy is preferable depends on its measured size, visible quality, and the application that will receive it. The format name alone cannot tell you which version to keep.
Start with a clean source
Upload .jpg or .jpeg files and inspect their previews. Choose a quality setting from 1 to 100. A starting value of 80 gives you something concrete to compare; it is not a claim about the percentage of quality or bytes preserved.
Select Process image, then compare the original and output thumbnails. Download a result and examine it at full size. Fine repeating textures, small writing, and smooth gradients are useful places to inspect. If the quality is insufficient, return to the original JPEG and increase the setting. Re-encoding an already converted copy adds another unnecessary processing step.
The converter keeps the source dimensions. If a picture is too wide for your intended use, resize it as a separate decision. This makes it easier to identify whether a change came from fewer pixels or a different encoding setting.
Work through a photograph example
Suppose your JPEG is 2000 by 1500 pixels. Export it as WebP at quality 80. The resulting image still has 3,000,000 pixels and the same 4:3 proportions. The output-size display tells you the actual bytes produced.
If that WebP looks acceptable and is smaller, it may suit the delivery workflow. If it is larger than the source, there is no need to replace the JPEG merely because the conversion completed. If the receiving application cannot open WebP, the source remains useful regardless of any size saving.
For a collection of event photographs, compare both a bright outdoor image and a detailed indoor image before selecting one shared quality. Similar dimensions do not mean identical compression behavior.
Save and organize the delivery files
You can select up to 20 JPEGs, with limits of 20 MB and 40 megapixels per input and 100 MB combined input/output. Individual downloads are useful for isolated assets; the ZIP keeps a batch together. Keep the source folder separate from exported copies.
Processing happens in your browser. Canvas export may remove metadata and color-profile information, so preserve originals when those details matter. Browser WebP export support is required; an export error may call for another browser or output format. Use Image Resizer when dimensions also need adjustment, or WebP to JPG for a later compatibility copy.
