After a long wait, I'm excited to announce that MConverter is now available on the Apple App Store!
Optimized for both iOS and iPadOS, the MConverter app offers more native integrations. At the same time, the user interface is the same as the one you know and love from the web version.
Here are just a few examples of what's now possible with the MConverter app, that couldn't be done before.

You were sent a file in some obscure format (or even something more common like a RAR archive), and now you can't open it. With the MConverter app installed, there's no need to worry. Just long-press the file in the Files app and select Open With > MConverter. You can then convert it to a more common format that your iPhone can handle, or even compress it if it's a PDF to save space. For example, you can convert a RAR archive to ZIP, which can then be natively extracted by iOS.

You can also send files to MConverter from any app that supports the iOS share sheet. Select one or more files, photos, videos, or other items, tap Share, and choose MConverter from the list of apps.
The selected items will be added to MConverter immediately, so you can start converting without first saving them to the Files app. This workflow is great for converting several photos or videos directly from your library.

Instead of having all converted files end up in the default Downloads folder, the MConverter app uses a dedicated folder in the Files app. This makes it easier to find your converted files and keep them organized.
Of course, you can also share them directly with other apps, without having to download them first.
The team and I would love to hear your feedback on the MConverter app for iPhone and iPad.
You can download the app from the App Store and leave a review.
