How PNG to BMP Conversion Works

Portable Network Graphics (PNG) uses lossless DEFLATE compression and supports a full alpha-transparency channel, preserving every pixel exactly as encoded. Bitmap Image (BMP) stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. The result is a standard BMP file readable by any compatible application. 1converter handles PNG-to-BMP conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.

When to use Low/Medium:

  • •Web uploads and social media sharing
  • •Email attachments with size limits
  • •Quick previews and thumbnails

When to use High/Maximum:

  • •Professional printing and publishing
  • •Archive and long-term storage
  • •When quality is more important than size

Image Tip: For photos, Medium quality offers the best balance. For graphics with text or sharp edges, use High or Maximum quality to preserve clarity.

Frequently Asked Questions

Everything you need to know about converting PNG to BMP

PNG can store an alpha channel, but standard BMP is typically opaque. If the BMP output doesn’t support alpha, transparent pixels become fully opaque (often with a default background).
Pixel data is preserved for the visible RGB channels, but BMP is usually uncompressed, so the file size changes. If your BMP variant supports limited formats, color depth conversion may reduce fidelity.
PNG uses compression for images, while BMP is commonly stored with little to no compression. That makes BMP significantly larger even when the image content is the same.
BMP is widely supported by legacy Windows tools and many basic image viewers because it uses straightforward bitmap headers and scanlines. However, very specific BMP variants (bit depth/color masks) may still vary by application.
