Image Fingerprint
Generate perceptual hashes for an image: average hash, difference hash and colour statistics. Unlike a checksum, these stay similar when an image is resized or recompressed, which is what makes them useful for finding duplicates. It is free, needs no account, and adds no watermark to your result.

Run up to 100 compatible files (250 MB total), receive a ZIP when multiple results need packaging, and choose the download name.
Average and difference hashes are computed from a downscaled greyscale version of the image, alongside colour statistics, and returned as JSON. Similar images produce similar hashes.
Calculate SHA-256, SHA-512 and MD5 checksums for uploaded files without changing their contents.
Inspect image dimensions, format, EXIF fields, camera data, orientation, DPI and embedded metadata as JSON.
Find the single dominant color of an image and export its HEX, RGB and pixel-share information.
Inspect file name, extension, MIME guess, size, timestamps where available and format-specific details for common media.
