Key Features & Benefits
Understanding Aspect Ratios and High-Quality Resampling
Resizing an image involves recalculating the grid of pixels that compose the image. When downscaling, pixels are blended using mathematical convolution filters (bicubic interpolation) to preserve sharpness without aliasing.
Locking the aspect ratio ensures that when you adjust width, height automatically calculates proportionately according to W / H = original ratio. This prevents awkward stretching or squishing.
| Common Standard | Dimensions | Primary Usage |
