Image Dimension Calculator
Calculate image file size from pixel dimensions, color depth, and compression format. Shows uncompressed and estimated compressed sizes for BMP, PNG, JPEG, and WebP.
How to Use Image Dimension Calculator
The Image Dimension Calculator estimates file size based on pixel dimensions, color depth, and compression format. Enter width and height in pixels, select color depth (1-bit to 48-bit), and choose a compression format (none, PNG, JPEG at various qualities, or WebP). See both the uncompressed raw size and estimated compressed size with compression ratio. Useful for planning storage requirements, estimating bandwidth for image delivery, or understanding how resolution and color depth affect file size.
Step-by-Step Instructions
- Enter image width and height in pixels
- Select color depth (8-bit, 24-bit, 32-bit, etc.)
- Choose compression format (none, PNG, JPEG, WebP)
- Click Calculate to see uncompressed and estimated file sizes
