Image File Size Calculator
Calculate the approximate uncompressed bitmap file size using image dimensions and bit depth. Enter width, height, and bits per pixel to estimate size in megabytes.

- 1920×1080 at 24-bit ⇒ 5.93 MB
- 800×600 at 8-bit ⇒ 0.46 MB
FAQ
Does this include compression?
No, it assumes uncompressed bitmap data.
What about alpha channels?
Include them in the bit depth if present.
Can I use it for JPEGs?
JPEG uses compression, so actual file size will be smaller.
Why divide by 8388608?
It's the number of bits in a megabyte (1024^2 bytes).
