Convert CRDOWNLOAD to IPA

The Google Chrome browser uses the .crdownload extension to indicate a file that is still being downloaded. To proceed, you need to ensure the file completes its download. Once the download is complete, the .crdownload extension will disappear, and you'll have the actual file you intended to download. It's impossible to convert a .crdownload file directly into an .ipa file.

If your original download was meant to be an iOS app (.ipa file), it should automatically be in the correct format once the download finishes. If the download was of a different file type, converting it to the .ipa file isn't straightforward because .ipa files are specifically formatted packages for iOS applications, which include the app itself and its metadata.

To summarize, ensure your download in Chrome-based browsers is complete to remove the .crdownload extension.
