Why Convert PNG to BMP?
BMP is a simple raster format that stores pixels without compression — useful for certain workflows:
- No new artifacts: Keep pixels intact for low-level editing.
- Straightforward structure: Easy for programs to read and manipulate.
- Legacy/embedded apps: Some Windows tools prefer BMP.
How to Convert PNG to BMP Online
- Click Upload PNG and select your file.
- Wait for processing to complete.
- Click Download BMP to save your image.
Defaults to 24-bit BMP with no compression.
BMP vs PNG Comparison
- File Size: BMP is typically much larger than PNG.
- Quality: Both are lossless (BMP uncompressed; PNG lossless compressed).
- Transparency: PNG supports alpha; common 24-bit BMP does not.
- Compression: BMP none; PNG lossless DEFLATE.
- Use Cases: BMP for legacy/pixel ops; PNG for web and efficient lossless storage.
Supported Limits & Formats
- Accepted input: PNG (
image/png) - Maximum file size: up to 16 MB per file
- Output: BMP (
.bmp, MIMEimage/bmp) - Bit depth: 24-bit (no alpha)
Troubleshooting
- Very large output: BMP is uncompressed; for smaller lossless, keep PNG.
- Need transparency: BMP 24-bit has no alpha; stay with PNG.
- Upload fails: Ensure the file is PNG and ≤ 16 MB.
- Yes, the converter is completely free with no hidden charges or subscriptions.
- BMP is widely supported on Windows and recognized by many other platforms. Modern web workflows usually prefer PNG/WebP for size efficiency.
- Often several times larger (e.g., 3–10× or more), because BMP is uncompressed.
- You can upload images up to 16 MB per file.
- Files are processed automatically and not retained longer than necessary for conversion.
- This page converts one file at a time. For bulk needs, repeat the process or use a batch tool.
- Standard 24-bit BMP doesn’t include alpha. Use PNG for transparency.
BMP output is intentionally large (uncompressed). For web delivery, prefer PNG/WebP/AVIF.
