Animated GIF raw size estimator
Estimate uncompressed frame data before GIF compression.
How to use the Animated GIF raw size estimator
What does the Animated GIF raw size estimator do?
Estimate uncompressed frame data before GIF compression; It applies this page-specific rule: raw size is width × height × frame count × bits per pixel, divided by eight.
Which inputs does this estimator use?
To estimate uncompressed frame data before gif compression, enter Width, Height, Frames, Bits per pixel; keep every value in the same example; select Calculate when the values are ready; Start with a familiar case covered by this rule - This estimates the uncompressed color-index data represented by all frames - so the expected result can confirm the settings.
How should the estimator result be read?
For a result intended to estimate uncompressed frame data before gif compression, this estimates the uncompressed color-index data represented by all frames; read bits per pixel together with the original width rather than as an isolated answer, and confirm that its units or structure match the intended use.
What calculation does this use?
When the goal is to estimate uncompressed frame data before gif compression, raw size is width × height × frame count × bits per pixel, divided by eight.
Why might a real result differ?
When using the page to estimate uncompressed frame data before gif compression, a real GIF can be much smaller because palettes, unchanged regions, and LZW compression affect the file.
Limits and accuracy
When using this estimator to estimate uncompressed frame data before gif compression, a real GIF can be much smaller because palettes, unchanged regions, and LZW compression affect the file; the result is an estimate unless every source value is known; codecs, metadata, overhead, and variable bitrates can change an actual file; keep width until the output has been checked in its intended destination. For a repeatable check when you need to estimate uncompressed frame data before gif compression, record Width alongside the final output and selected options.
