How to Convert PNG to BMP

Both PNG and BMP can store image data without lossy compression, but they do it differently — PNG applies lossless compression to shrink the file, while BMP traditionally stores pixel data in a raw, uncompressed grid. Some older Windows applications, embedded systems, and specific legacy tools expect this simpler BMP structure rather than PNG's compressed format, since BMP is easier for minimal software to read directly without needing a decompression step.

One thing to note when converting: BMP's standard format doesn't support an alpha channel the way PNG does, so transparent areas in your PNG files will typically be filled with a solid background color in the resulting BMP, depending on the specific BMP variant used.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single PNG.
3. Drag your PNG file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to PNG and the "To" format to BMP.
5. Click Convert. BMP files are written to the output folder, fully offline.

• 100% offline — your images are never uploaded anywhere
• Bulk conversion of entire folders, including sub-folders, in one click
• Produces standard uncompressed BMP files readable by legacy software
• Multi-core processing for fast handling of large batches
• Option to delete original PNG files automatically after conversion
• No recurring subscription or hidden upload limits

If you only need straightforward format conversion without RAW or HEIC support, Turbo Batch Image Converter Lite covers this exact PNG-to-BMP conversion in a lighter, more focused app.
