Image, audio & video calculators

Estimate pixel counts, raw data sizes and encoded media budgets.

Choose the right calculation

Uncompressed pixel and PCM estimates use a predictable data layout. Compressed media sizes depend on codec and content. Average encoded bitrate can estimate file size but does not by itself establish quality.

Will an uncompressed image estimate match a JPEG file?

Usually not. JPEG uses compression, so its final size depends on the image and encoding settings.
