Resizer is a batch image resizing utility built around a simple drag-and-drop workflow. Drop in a folder of images, configure your target dimensions, and process them all in one pass.
Flexible aspect ratio fit methods let you choose how images scale to the target size: fit within bounds, fill and crop, or stretch. Output can be saved in a different format from the source, with a customizable filename pattern for organizing the results.
Supported image file formats: BMP, GIF, PNG, JPEG, and TIFF.
