How do I recover 0 bytes of a JPEG To recover data that is lost in a zero-byte file, the best solution is to ask the person who sent it to you to send you the file again using a different program, if possible. ![]() Test 3, 'Lost intro', saw us delete the first 8KB of every file (that is, the corrupted file started at original file byte 8193). This would be a little more difficult to fix, but should still be recoverable. Free Trial - Worldwide unique recovery of damaged pictures and broken JPEG headers.

Test 1, 'Zero Signature', was the simplest: we just zeroed the first two bytes in every image. And so we set about creating some, by intentionally damaging four groups of images in very specific ways. To benchmark our repair tools we needed some corrupted JPEGs.
