Estimate an image's file size from its dimensions.
Estimate of the uncompressed size. A real JPG or PNG file will be much smaller thanks to compression.
Estimate an image’s uncompressed file size from its dimensions and color depth. Useful for understanding memory requirements, video frame sizes, and why compressed files are much smaller.
Input: dimensions + bit depth. Output: estimated uncompressed size.
This is the uncompressed (raw) size; real JPG/PNG files are much smaller due to compression.
JPG and PNG use compression. The calculator shows the raw uncompressed size, which is an upper bound.
8-bit per channel (24-bit RGB) is standard for most images; 32-bit includes an alpha (transparency) channel.
