SMART CALCULATOR / PLAN WITH CONFIDENCE

Image File Size Calculator

Estimate uncompressed image memory from dimensions, colour depth, and image count before choosing a format or workflow.

Use boundary

Calculation path

We multiply the number of pixels by the colour depth and convert bits to bytes and megabytes.

Calculation path

Bytes = width x height x bits per pixel / 8 x image count.

What you provide

Width in pixels: Horizontal pixel count. Enter a whole-number value for this planning input.
Height in pixels: Vertical pixel count. Enter a whole-number value for this planning input.
Bits per pixel: Colour depth such as 24 for RGB. Enter a whole-number value for this planning input.
Number of images: How many same-sized images you need to store. Enter a whole-number value for this planning input.

What you receive

Use boundary

Use this for memory and rough storage planning, not as a prediction of a compressed download size.

Results are estimates for planning. Confirm rates, rules, and source documents before making a financial, health, or purchase decision.
