Texture Resizer

Texture resizer analyzes a raster input and outputs a resized texture suitable for engines and asset pipelines. It supports PNG, JPEG, and WEBP input. Users provide target width and height or a scale factor; the tool can produce an exact size or uphold aspect ratio. It offers fit and crop modes, and outputs in PNG, JPEG, or WebP with adjustable quality. Optional features include alpha preservation, metadata handling, and batch readiness. It does not modify vector textures or perform color-space conversions beyond a standard sRGB output. Alpha preservation is optional to keep transparency intact.
Under the hood, the tool computes the new dimensions using standard image resampling techniques. If both width and height are provided, it derives a scale factor. For fit, scale = min(targetW/oldW, targetH/oldH); for crop, scale = max(targetW/oldW, targetH/oldH). If only one dimension is given, the other is derived from the source aspect ratio. Interpolation options include nearest, bilinear, and bicubic; higher-quality options produce smoother textures at the cost of processing time. The approach ensures that texture sharpness and transparency are handled predictably across outputs and formats.
Typical use cases include preparing textures for games across engines, optimizing web textures for bandwidth, or aligning asset sizes for mobile devices. Outputs include the resized image, the resulting width and height in pixels, and the file size. The tool emphasizes deterministic results and provides explicit validation for invalid inputs, such as non-image files or zero or negative dimensions. Advanced users can batch multiple files and inspect per-file results to ensure consistency across a texture atlas or material set.
