Understand the formats

JPG / JPEG

JPEG stores raster photographs with lossy compression. JPG and JPEG are two extensions for the same format.

Choose JPG for photographic images when a receiving app needs a widely supported format. Inspect fine text and edges after reducing quality.

JPG does not store transparent pixels. A PNG-to-JPG conversion must fill the background. Saving an existing JPG as PNG cannot restore detail already lost in the JPG.

WebP

WebP supports lossy and lossless image compression, transparency and animation. A tool may support only a subset of those features.

Convert a still WebP image to JPG when a receiving application rejects WebP, or to PNG when a transparent background matters.

Coverton’s browser image tools export still images. Do not use a still-image conversion to preserve an animated WebP sequence. Output size depends on the source and chosen quality.

When is this useful?

Compare the actual size of a JPEG photo re-encoded for the web. A WEBP copy is not guaranteed to be smaller.

Input and result example

photo.jpg → photo.webp

Examples illustrate the workflow; actual size, support and recognition depend on the source and settings.
