Bit Depth Guide

32-bit

RGBA with Alpha - Full color with transparency support. Highest quality, largest file size.

24-bit

RGB True Color - 16.7 million colors. Standard choice for most images.

16-bit

High Color - 65,536 colors. Good balance between quality and file size.

8-bit

Grayscale - 256 shades of gray. Ideal for black and white images.

4-bit

16 Colors - Limited palette. Small file size, suitable for simple graphics.

1-bit

Black & White - Monochrome. Smallest file size, best for line art.

PNG vs BMP Comparison

PNG Format

  • Lossless compression for smaller files
  • Native transparency (alpha channel) support
  • Ideal for web graphics and logos
  • Widely supported across platforms

BMP Format

  • Uncompressed for maximum editing flexibility
  • Native Windows format with broad compatibility
  • No quality loss from compression artifacts
  • Fast load times (no decompression needed)

Frequently Asked Questions

PNG uses lossless compression to create smaller files while maintaining quality and supports transparency. BMP stores uncompressed image data, resulting in larger files but maximum quality preservation and editing flexibility. BMP is also more widely compatible with Windows applications and legacy systems.

Choose 32-bit if your image has transparency you want to preserve. Use 24-bit for standard color images without transparency (most common choice). Select 16-bit for smaller files with acceptable quality loss, and 8-bit or lower for simple graphics or when file size is critical.

You can either preserve transparency (32-bit only), replace transparent areas with white or black backgrounds, or choose a custom background color. The converter automatically detects transparency in your PNG and suggests the best handling method.

BMP is an uncompressed format, meaning it stores every pixel's data directly without any compression. PNG uses lossless compression to reduce file size. The larger BMP file size is expected and provides benefits like faster loading times and no decompression overhead.

Yes, we accept PNG files up to 10MB in size. The converted BMP file will typically be larger than the original PNG due to the uncompressed nature of the format. The exact size depends on image dimensions and chosen bit depth.
