BMP to PNG Batch Converter

Convert BMP images to PNG in bulk, fully offline

Why Convert BMP to PNG?

BMP is an uncompressed Windows bitmap format that produces very large files. PNG is a lossless format that preserves transparency and sharp edges. Whenever a folder of BMP files needs to move into a workflow, platform, or tool built around PNG, converting each file by hand doesn't scale past a handful of images.

Turbo Batch Image Converter Lite batch converts an entire folder of BMP files to PNG in one pass, including nested sub-folders, all processed offline on your own Windows PC with no upload limits.
