Corrupt JPEG Checker scans your folders for damaged JPEG files and tells you what's wrong — before a single memory is lost. Whether you're a photographer managing thousands of shots, an archivist preserving irreplaceable images, or just someone who wants peace of mind, this app has you covered.
Detecting two distinct types of corruption:
• Visual Corruption — the image data itself is damaged, causing glitches, colour shifts, grey bars, or missing sections when the photo is displayed.
• Meta Corruption — the file's header or structure is malformed, which can cause software to misread, skip, or fail to open the image entirely.
Each file is clearly flagged so you know at a glance which photos need attention, and which are safe.
KEY FEATURES
• One-Click Scanning — browse to a folder, hit Scan, and let the app do the rest.
• Recursive Search — automatically digs through every subfolder so nothing is missed.
• Instant Preview — press the space bar to see exactly how corruption affects any image.
• Batch Move — quarantine corrupt files to a separate folder for review.
• Batch Delete — remove damaged images you no longer need in a single action.
• CSV Export — save your scan results for spreadsheets, audits, or record-keeping.
• Filter by Type — view only visually corrupt, only meta corrupt, or both.
• Full File Paths — always know exactly where each file lives on disk.

This program will identify corrupt picture files. It does this quite well. I thought it would also repair them which it does not. My corrupt files were already identified by my Mac, either the preview wasn't there or only partially there so just wasted 9 bucks. I'll have to be more careful how I phrase my searches I guess.
Wish I’d found this a long time ago

Thank you for this tool!I’ve spent months trying to dig corrupt images out of a 600GB iPhoto library spanning more than a decade. Reimporting my library into a fresh one is crashing, presumably during thumbnail and preview generation of the imported files. iPhoto only logs that a corrupt file was found, not which one - then crashes.I’m running this tool on the library right now. It’s already found a few that when opened in Preview are obviously damaged. CJC is spitting out a text file with paths to all the damaged photos. I’m hoping that by morning my iPhoto problems are behind me.
It’s just what I was looking for.

I’ve had some file system errors on mirrored external disks and was worried about internal damage to thousands of image files. Disk Warrior cleared up the file system errors (mostly Spotlight-generated files) but I couldn’t manage to compile some Public Domain command-line image validation tools I’d found.Corrupt JPEG Checker has flagged lots of files I already knew were damaged (generated by a flakey Canon camera I used to use) and it appears to validate the image data from every file. Metadata errors don’t necessarily mean an image is affected but it’s sure nice to know.Thanks!
great jpeg scanner utility

I had been noticing intermittently that some jpegs whose thumbnails looked ok in Windows Explorer could not be opened. I could never figure out how widespread the problem was, other than by trying to open every single jpeg and look manually. Clearly impossible. And worrying - did I have a bad disk? a corrupt NTFS, etc.. It turns out the contained thumbnails were fine (which is all Windows uses, until you actually try to open the enture photo using Photo Viewer or equivalent). Photoshop, Irfanview etc all failed the same way. The file contents were trashed. Jpeg recovery programs can’t work. Then I found corruptJpegScanner for my Mac. And I tried it out. And it found 64 corrupt files among my 36k. Saved! $6 very well spent. It turns out that (with one exception) they had all been created by the same scanner, so I blamed that. Rescanned, and all is now clean.
