- proportional resize based on only one side, width or height
- percentage-based scaling with a draggable resize slider
Common use cases

- scale down large images before uploading to a website or form
- organize large photo exports into web-friendly dimensions
Exact-size mode
Exact-size mode supports two different behaviors:
- Stretch to target size: directly output the target width and height
- Crop to target size: fill the whole target box and crop the overflow
When crop mode is selected, you can also choose the crop alignment, such as top left, center, or bottom right. This is useful when you want to keep the main subject visible in cover images, thumbnails, banners, or profile images.
Proportional resize mode
Proportional resize mode keeps the original aspect ratio. You only need to choose one control side:
- resize by width
- resize by height
After you enter one value, the other dimension is calculated automatically. This mode is useful when you want all images to share the same width or the same height without distortion.
