Analyze a file. It never leaves your machine.

Your browser reads the bytes in this tab and reports what it can measure: the content type from the file's own signature, its size and SHA-256, an image's colour type, bit depth, alpha, profile, resolution, dominant colours and brightness, and a text file's encoding, line endings and word count. There is no server behind this page and no upload.
