Enter the known values in the units shown. Results update as you type.
Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
Use the worked example to check the method. Reset restores the starting fields.

A 1,000 × 1,000 image at 24 bits per pixel contains 24,000,000 bits: 3,000,000 bytes or 3 MB before headers, padding and compression.

Pixel data bits = width × height × bits per pixel

Enter these known values and leave the other values blank.

Bit depth here is total bits per pixel across channels. An 8-bit-per-channel RGB image normally needs 24 bits per pixel; channel count is not added automatically.
The result is ideal packed pixel data. File headers, metadata, row padding, layers, color profiles and compression are excluded. It does not predict a JPEG, PNG or camera RAW file size.
Pixel dimensions are positive whole numbers. A theoretical result may contain fractional bytes at low bit depths; actual files require whole-byte storage and may pad each row.
Decimal MB uses 1,000,000 bytes; MiB uses 1,048,576 bytes. A byte contains exactly eight bits.

Compression and file structure change the stored size. This model measures only an uncompressed pixel payload and excludes headers and padding.

For three 8-bit color channels, choose 24 total bits per pixel. Eight bits per channel and eight bits per pixel describe different amounts of data.

Bookify requires whole positive pixel dimensions while preserving the captured payload equations and unit conversions.
