Frequently asked questions
Where is the processing performed?
The file or text is sent to the server for processing. Before starting, read the terms and conditions on the tool page and agree to it. Download the finished result before the expiration date indicated on the page.
What to do if the result is not suitable?
Take the original file or text and try other settings in the steps above. Compare the new result with the previous one. The original files on your device remain unchanged.
Features and limits

The scan shows archive reading errors, but does not look for viruses. A successful report does not mean that any files inside are safe to open.

.zip, .tar, .tar.gz, .tgz, .7z → .txt

50 MB / file; 100 MB in total; 20 files.

The integrity check is not a virus check.

The upload starts only after you agree and start processing. The result’s storage period will be shown when processing finishes.

Open integrity_report.txt: it shows how many files were read. If an error occurs, try downloading the archive again or opening it in a program that supports this format.
