In their own words
DiskTuna
DiskTuna’s JPEG-Repair Toolkit combines JPEG-Repair for damaged photos with JpegDigger for recovering lost images. It runs on Windows 7, 8, 10, and 11 and processes files locally on the PC, without uploading them to remote servers. JPEG-Repair addresses corrupt headers, invalid markers, bad-sector damage, and JPEG bitstream errors with visual feedback. It can recover JPEG data from corrupt RAW photos such as Canon CR2 and Nikon NEF files, and does not re-encode JPEG images. The demo shows low-resolution previews; the full version enables high-quality saves. Repairing a corrupt JPEG header requires a reference photo made with the same camera and settings. The toolkit specializes in JPEG and specified RAW formats and does not repair PNG files. The listed plan includes both tools and is billed at €29.00–€49.00, excluding applicable taxes. Downloads are unsigned and may trigger Windows SmartScreen warnings, including after updates. The maker offers a refund only when the demo works on the files but the full version fails on those same files.
