- Fast processing - BMP files load quickly in legacy apps
About Converting PNG to BMP
PNG is a lossless raster image format that supports a full alpha-transparency channel. It is the standard choice for screenshots, logos, icons and any graphic with sharp edges or text where quality must be preserved exactly. When you need to move away from PNG, the usual reason is simple: larger files than jpg for photographs.
Converting your PNG image to BMP solves that. BMP is an uncompressed Windows raster format that stores each pixel verbatim. Files are very large, so BMP is normally converted to a compressed format for storage or sharing. In practice you gain no compression artifacts and simple, well-documented structure. PrivConvert runs the whole PNG-to-BMP conversion in server memory and deletes your file the instant the BMP is ready — nothing is stored, logged or reused.
When this conversion helps
- You need no compression artifacts
- You need simple, well-documented structure
- Sharing a PNG image with someone whose software expects BMP
Tips for best results
- BMP preserves quality exactly, so the conversion from PNG will not introduce any new compression artifacts.
- PNG can store transparency but BMP cannot — transparent areas will be filled with a solid background.
- For the smallest possible BMP without visible quality loss, start from the highest-quality PNG you have.
- Files up to 250 MB are supported, and you can batch-convert several PNG files at once; each is processed privately and deleted immediately.
