Rebuild a damaged file from the data it still holds
Losing a file is worrying. Crdownload looks for the data that is still intact and, if it finds any, writes a new file that opens. The result depends on the damage, and your original stays untouched.
It runs like a local application: your file is never uploaded, so there is no account and we set no usage limits.
How it works
- Choose the file
The original stays untouched. Only a copy is read in memory.
- The structure is read
The format is identified from the content, even without a header. Indexes and sizes are rebuilt from what the data shows, and damaged zones are cut out.
- Download the result
You receive a file with the intact data and a report of what was kept, dropped or inferred.
Where it works best
Interrupted downloads
.crdownload, .part and .opdownload files, when the link no longer works.
Videos that will not play
MP4, MOV, MKV and AVI, including a video cut off before its index arrived.
Archives that will not open
ZIP, RAR, 7z and tar. Each file inside is also processed.
What to expect
Data that never arrived cannot come back: a video cut at 60% returns as that 60%, with damaged passages removed and nothing invented. Sometimes nothing usable remains. If the file can still be downloaded, that will always give a better result.
