Im not even sure if we have this kind of technology yet but is there some kind of program that can attempt to repair broken jpeg files even with a low chance of success?

No recommendations here, but if you Google: https://www.google.com/search?q=broken+jpeg+file&ie=utf-8&oe=utf-8


I never make the same mistake twice....I always make it 5 or 6 times just to be sure!

I would suggest trying some of the free ones, at this link.... http://www.jihosoft.com/free-utilities/jpeg-repair-tool.html

If possible, backup the broken jpegs first. If the first free one is a no go, continue on to the next one etc.

Exercise caution installing the freeware choices & avoid any offers to install other unwanted software/utilities etc.

Not that this is directly related to the original question, but it is to the installation of freeware now that the loathsome practice of bundling is ubiquitous.

 

I really cannot recommend the Unchecky program highly enough.  I'm awfully good about always using "advanced mode" or its equivalent and reading the various dialogs that come up, but it's even saved me on several occasions by unchecking an "offer" that I somehow missed (and it notifies you that it's doing so such that you can check it again if it happens to be something you really want - which is exceedingly rare in my experience).

I know it's an old topic but I made one! Free version actually works and allows you to repair JPEGs. Only limitation is batch mode is disabled.

 

I have repaired zillions of JPEGs, and most effective method for repairing header damage actually is, grabbing the header of a known good file and stick that on the corrupt jpeg using a hex editor.

 

Using HxD (free) this means:

 

Sample

 

Sample should be known good file shot with same device, with same settings. Search for last instance of the byte combo FF DA. Copy everything from (and including FF DA) to start of file to new file. Call it header.dat or whatever.

 

Corrupt file

 

Find last instance of FF DA (if any, file can be too corrupt) and delete everything in front of it. Open header.dat, select all, copy and switch back to corrupt file. Go to offset and select paste insert. Save file as rescued.jpg or whatever.

 

If damage was limited to the header, file is now fixed.

 

I have made a tool that automates this (and which does some more): https://www.disktuna.com/jpgrepair-fix-and-repair-corrupt-jpeg-headers-and-invalid-markers/

 

Free version is functional, it saves repaired jpegs, just batch mode is disabled.

 

If this is considered spam or spammy, let me know and I'll remove the URL.
