Convert BMP to PNG

Modernize large legacy BMP files from scanners and old Windows apps as PNG images. PNG keeps the decoded pixels lossless while usually being easier to share and edit.

About BMP and PNG conversion

BMP is compatible with old software, but it is a poor everyday exchange format because files can be very large and some web tools reject it. PNG is widely supported by browsers, editors, documents, and issue trackers.

Use BMP to PNG when the source has screenshots, diagrams, UI captures, scans with text, or other sharp detail where JPG compression would be a bad trade. The conversion stays in the raster worker and writes a PNG from the decoded bitmap.

PNG is lossless from the decoded BMP pixels, but it is not guaranteed to be tiny. Photo-like BMP files may still be larger as PNG than as JPG; the benefit is fidelity and modern compatibility rather than maximum compression.

FAQ

Is PNG better than JPG for BMP screenshots?

Usually yes. PNG preserves sharp text, flat colors, and interface edges without introducing JPG compression artifacts.

Will BMP to PNG reduce file size?

Often it will, especially for simple graphics, but complex photo-like images may still need JPG if the smallest shareable file matters most.

Is BMP to PNG lossless?

The PNG stores the decoded BMP pixels losslessly, so it is the safer target when you need an editable or reviewable copy.

Why convert old BMP files at all?

PNG is accepted by far more modern web apps and design tools, while BMP can be bulky and inconvenient outside legacy software.
