Raster Memory Estimator
Estimate raw pixel storage from dimensions, channels, bit depth and layers.
Uncompressed pixel data
68.66 MiB
72 MB · 24 megapixels
Width × height × channels × bytes per channel × layers. MiB uses 1,048,576 bytes; MB uses 1,000,000 bytes.
This is raw pixel storage, not a prediction of JPEG, PNG or PSD file size or application RAM. Compression, masks, previews, history and partial layers change real usage.
