JPEG vs WebP for a Product Photo
This case shows why the smaller format is not always the same setting across encoders.
Case result
- Input: photo-style sample.
- Steps: compare JPEG q80, WebP q80 and WebP q70.
- Output: WebP q70 gives 249 KB.
- Limit: JPEG q80 can still be the safer fallback.

| Stage | Setting or check | Measured result | Decision | Limit |
|---|---|---|---|---|
| Input | Photo-style sample | 1.37 MB q100 | Compare formats | Generated sample |
| Step | JPEG q80 | 303 KB | Fallback candidate | JPEG only |
| Step | WebP q80 | 346 KB | Not smaller here | Encoder behavior varies |
| Output | WebP q70 | 249 KB | Small modern output | Check destination support |
Steps
The workflow records the original format and size, tests one or more output settings, checks the visible result and keeps the smallest result that still fits the task.
