About this Tool
Enlarge small or low-resolution images with advanced canvas interpolation. By applying cubic and bilinear smoothing filters on the canvas, this tool expands graphics to higher pixel dimensions while minimizing sharp aliasing or ugly pixelation artifacts.
100% Secure Local Processing Active
This tool runs entirely on your device via WebAssembly and browser Canvas. No files are ever sent to any remote server, ensuring complete data security.
How to Use
Select a low-resolution graphic or small icon.
Choose your expansion multiplier (e.g., 2x, 4x) or enter custom enlarged dimensions.
Download the processed output with smoothed pixels.
Perfect For
Blowing Up Low-Res Icons
Enlarge retro graphics, small app logos, or pixelated icons to higher dimensions for print or high-DPI displays.
Preparing Web Thumbnails for High Resolution
Convert small product thumbnails into larger, viewable display cards without severe jagged edge aliasing.
Zooming into Photo Details
Enlarge a specific segment of a scanned photo to inspect small details and text cleanly.
Frequently Asked Questions
No, image enlargement scales up existing pixel matrices. Advanced canvas interpolation smooths out edges and transitions so the output doesn't look like blocky blocks, but it cannot generate fake AI data out of nothing.
PNG is highly recommended to preserve the smoothed edges without introducing messy compression artifacts common in JPG files.
