PNG vs BMP Format Comparison

Aspect PNG (Source Format) BMP (Target Format)
Format Overview
PNG
Portable Network Graphics

Raster image format with lossless DEFLATE compression and full alpha transparency support.

Lossless
BMP
Bitmap Image File

Simple raster format storing uncompressed or RLE-compressed pixel data without quality loss.

Uncompressed
Compression

Lossless DEFLATE compression preserving exact pixel data.

Typically uncompressed or simple RLE compression; no data loss.

Color Depth

Supports truecolor (8-bit and 16-bit per channel) and indexed palettes.

Supports 1-bit to 24-bit or 32-bit per pixel with optional alpha channel.

File Size

Moderate sizes (100 KB–10 MB) depending on dimensions and transparency.

Large sizes (500 KB–50 MB) scale with resolution and bit depth.

Transparency

Full alpha channel support for complex transparency and compositing.

Alpha support in BMP v4+; not universally supported.

Advantages
  • Lossless compression
  • Full alpha transparency
  • Wide web browser support
  • Simple uncompressed format
  • Excellent compatibility on Windows
  • No compression artifacts
Disadvantages
  • Larger than lossy formats like JPEG
  • No animation support
  • Very large file sizes
  • No native web support without prior conversion
  • Limited metadata capabilities

Why Convert PNG to BMP?

Converting PNG to BMP provides a straightforward, uncompressed image format ideal for legacy applications and pipelines that require raw bitmap data without compression artifacts.

Our converter preserves full pixel information and transparency where supported, ensuring maximum fidelity for editing and processing in environments lacking PNG support.

Use BMP outputs for Windows-based software, printing workflows, and archival storage where uncompressed, exact pixel representation is needed.

Key Benefits:

  • Pixel-perfect, uncompressed images
  • Wide compatibility with editing tools and libraries
  • No quality loss on repeated saves
  • Fully browser-based—no installation required
