Frequently Asked Questions
How does bicubic enlargement reduce blocky pixelation?
Instead of simply duplicating pixels (nearest-neighbor), bicubic interpolation calculates weighted color averages across a 16-pixel neighborhood, producing smooth gradients and clean edges.
What is the maximum scaling factor available?
You can enlarge images up to 4x their original pixel dimensions, or specify custom pixel widths up to your browser’s canvas memory limits (typically up to 8,192 pixels).
Can this tool enlarge vector SVG files as well?
For vector SVGs, we recommend using our SVG Converter tool which re-renders paths mathematically at any scale with zero interpolation required.
