Accepted formats: .png, .jpg, .jpeg and .webp. Limits: 500 files, 1 GB total and 256 MB per file. If the file count is exceeded you will see "This set will not be analyzed because it exceeds the 500 file limit." and if the size is exceeded "This set will not be analyzed because its total size is too large to process safely in the browser." This tool does not modify original files: the ZIP is a copy and hashes never leave the browser.
