How it works
The browser decodes the source, calculates output dimensions from the selected fit rule, resamples the pixels, and encodes a new image.
Important limitations
- Enlarging a small source cannot create missing detail.
- Cover can crop edges; contain keeps the full image within the target bounds.
- Very large decoded images can exceed browser memory limits.
Useful for
- Create consistent website thumbnails.
- Fit photos to avatar or social dimensions.
- Reduce pixel dimensions before another conversion.
