Bulk Sprite Resizer

The Bulk Sprite Resizer performs batch resizing of sprite images to meet uniform target dimensions across large sprite packs. It accepts multiple input formats (PNG, JPEG, WEBP) and preserves transparency where applicable. The tool supports resizing by explicit width/height, a scale factor, or both, with an option to maintain aspect ratio. Optional padding allows canvas expansion to prevent edge clipping when sprites are rendered in engines that require padding. Advanced options include batch atlas generation by specifying atlas_columns to layout frames efficiently for sprite sheets. The core processing pipeline reads each input image, computes the target canvas size, applies a chosen resampling method (bilinear by default, with optional bicubic), and outputs consistently named assets. Outputs include the resized individual frames and, if requested, an atlas file. This tool is designed for game developers, asset pipelines, and independent artists who need consistent sprite dimensions across dozens or hundreds of assets without manual edits. It emphasizes non-destructive handling of transparency and minimal quality loss when formats are preserved or converted. Typical use cases include preparing sprites for multiple resolutions, exporting to common engines, and generating uniform sheets for animation frames. Core differentiators include batch throughput, explicit aspect-ratio control, padding options, and optional atlas generation, all integrated into a single processing step. The tool targets developers and studios seeking deterministic asset sizing with minimal manual intervention and reproducible results across builds.
