Expert Insight: Understanding Resampling Algorithms
When you resize an image, you're not just changing numbers—you're asking a mathematical algorithm to "invent" or "recalculate" pixels. Our tool uses high-quality lanczos/bicubic resampling to ensure that your images remain sharp even when scaled up or down.
Bilinear vs. Bicubic
Bilinear interpolation is fast but can leave images looking soft or blurry. Our engine defaults to bicubic interpolation, which looks at a 4x4 grid of surrounding pixels, producing much smoother transitions and sharper edges in your resized photos.
Avoiding Artifacts
To avoid "aliasing" (jagged edges), we recommend resizing in even increments when possible. If you need to scale up significantly beyond 200%, consider using our AI Super-Resolution (coming soon) or multiple passes of sharpening to retain professional clarity.
