scanogram

Scan your pictures and videos for corruption, and sort them by EXIF or modification time.

Introduction

This tool is a fast and lightweight scanner for potentially corrupted pictures and videos, for example after disaster recovery of a hard drive. It works by parsing the file structure, and not reading the entire file. This tool can also sort your multimedia files based on date, using EXIF where possible and modification time as fallback.

The following formats are supported for corruption checking:

• JPEG
• TIFF
• PNG
• HEIC

Sorting by EXIF time uses exiftool, so all formats supported by the tool also work here.

Sorting by modification time works on all files.

Usage

Make sure you have exiftool installed and added to your PATH (executable by typing exiftool in any Terminal).
