Estimate the raw uncompressed file size of any image from its dimensions and bit depth. Includes a rough JPEG estimate so you can catch oversized assets before they ship.
Raw uncompressed size
—
When would you use this?
Before you start working with an image, or before you commit to exporting at a specific resolution, it's useful to know roughly how large it's going to be. This calculator gives you the raw uncompressed file size based on dimensions and bit depth, plus a rough estimate of the compressed JPEG size. It won't be exact since compression varies enormously with image content, but it'll tell you if you're heading toward a 5MB hero image before it's too late.
