JpegDigger is a more advanced JPEG recovery tool than the average end-user tool. Initially made for my own use only to recover JPEGs for clients, it has helped me recover JPEG photos where every other tool I tried under performed. It may not be pretty but all of the tool’s functionality were developed in answer to real-world data loss scenarios.

JpegDigger can work with physical devices too
No file system detected? Cluster/block size unknown? No problem, click help me determine values
Default options are okay for most scenarios: Skip corrupt files and avoid duplicates.
Reconstruct fragmented files manually by picking clusters
Like a true data recovery technician you can image SD Cards prior to recovering individual files. Entropy map shows if you’re imaging actual data. JpegDigger can work with YKUSH USB power control to power cycle unstable SD Cards and USB Flash Drives.
