A 716-byte WebP becomes a 10,742-byte JPG

An original trail-pack illustration, converted for a JPEG-only handoff. This is a compatibility example, not a compression success story.

What was actually tested

We selected this WebP in Image to JPG’s WebP converter, kept both dimension fields empty, retained quality 90% and the default white background, converted and downloaded the result. We reopened the downloaded file to check its format and dimensions.

The input has an alpha channel; the JPG is RGB with a white corner pixel (255, 255, 255). The output keeps the 600 × 400 dimensions and is about 15 times the input’s byte size. This simple flat illustration compresses very efficiently as lossless WebP; it is not a benchmark for photographs.

When to use this workflow

Make a JPG copy when a receiving editor or upload form needs JPEG. Keep the WebP master for transparency. Compare bytes and pixel dimensions before sending; conversion alone does not guarantee a smaller file.
