🔍 Image Enlarger

Upload your image, select your scale (2× is the best balance of quality and size), set sharpening to Medium, and click Enlarge. The tool uses progressive step-scaling — multiple small passes instead of one large jump — which preserves more detail than single-pass enlargement.

For images with clear, sharp original content, 2× enlargement with Medium sharpening produces excellent results. Very blurry or low-resolution originals will remain soft after enlargement — upscaling cannot create detail that was never captured in the original.

This tool supports up to 4× enlargement. For a 500×500px image, 4× produces a 2000×2000px output. For very large outputs (over 8 million pixels total), sharpening is automatically skipped to prevent browser slowdown.

Sharpening applies a 3×3 unsharp-mask convolution that enhances edge contrast, making the enlarged image appear crisper. Off produces the smoothest result. Max produces the sharpest edges but can introduce halos. Medium is the best default for most images.

2× enlargement produces noticeably better quality than 4× because each progressive step introduces less interpolation error. Use 4× only when you need the size and are prepared to accept some quality reduction. For printing, 2× is recommended.
