Bits stored per pixel. More bits = larger file but richer color or tone range.
Multiply by more than 1 to estimate total storage for a batch or shoot.

  • Your 3840 x 2160 image has 8.29 megapixels (8,294,400 total pixels).
  • At 24 bits per pixel, the raw uncompressed data is 23.73 MB. This is the theoretical minimum size before any format container or metadata is added.
  • For web delivery, WebP lossy (~1.07 MB) is typically 10-30% smaller than JPEG (~1.19 MB) at equivalent visual quality.

Next stepFor web images, WebP or AVIF give the best file size with minimal quality loss. For professional editing, keep the uncompressed or TIFF copy.
