What happens to your file
WebP is encoded at quality 90 with compression method 6, the slowest and most thorough setting, which is why WebP output is typically smaller than the JPG or PNG it came from at comparable quality.
Settings this conversion runs with
| Engine | Pillow (Python Imaging Library) |
|---|---|
| Quality | 90 by default |
| Effort | method 6 — highest compression effort |
What changes
- Nothing in the picture is resampled unless you ask for it — resize, crop-to-aspect, and background removal are opt-in, so a plain AVIF to WEBP keeps the original pixel dimensions.
