Image Resize

Scale images 2×/3×/4× with Lanczos3 resampling

Resize images by a scale factor using Lanczos3 pixel resampling — the highest-quality algorithmic upscale method. Optional unsharp mask for edge sharpening after resize. Max output: 8000px. Not AI-based — purely algorithmic.

How it works

Accepts a multipart image upload with a scale parameter. Applies Lanczos3 resampling via Sharp and returns the resized image binary with dimension headers.
