Support

MediaConvert supports 11 image formats for both input and output conversion:

• Common web formats: JPG / JPEG, PNG, WebP, GIF, BMP
• Modern high-efficiency formats: AVIF, HEIC, HEIF
• Professional / specialty formats: TIFF, ICO

You can convert any supported input format to any supported output format in a single step. For example, convert HEIC photos from your iPhone into JPEG or WebP for sharing on the web.

Audio (10 formats): MP3, AAC, FLAC, WAV, OGG, M4A, WMA, OPUS, AIFF, ALAC

Video (11 formats): MP4, AVI, MOV, MKV, WebM, FLV, WMV, M4V, 3GP, TS, OGV

All conversions are performed locally on your device. Quality settings can be adjusted before starting a conversion.

If MediaConvert fails to launch, try the following steps in order:

• Restart the app: Close the app completely from the System Tray or Task Manager, then reopen it.
• Restart your PC: A full restart clears system resources that may be blocking the app.
• Check Windows version: MediaConvert requires Windows 10 version 1809 (October 2018 Update) or later. Open Settings → System → About to verify your version.
• Repair the app: Go to Settings → Apps → Installed Apps → MediaConvert → Advanced Options → Repair.
• Reinstall: Uninstall MediaConvert from Settings → Apps, then reinstall from the Microsoft Store.
• Check for Windows updates: Ensure your system is up to date, as some dependencies require recent Windows components.

If none of these steps help, please report the issue (see the Bug Report section below) and include your Windows version number.

After conversion completes, a "Save As" dialog will appear, allowing you to choose exactly where to save the output file. By default, MediaConvert suggests the same folder as the source file with the new extension applied.

You can also find all past conversions in the History tab within the app, which shows the original input path, output path, and conversion status for each task.

Yes! Batch processing is one of MediaConvert's core features. Simply drag and drop multiple files into the app window — you can mix images, audio files, and videos in a single batch.

Each file is tracked individually with its own progress indicator. Files are processed in parallel where your system resources allow, so large batches complete efficiently.

After dropping a video file into the app, select the operation from the dropdown menu:

• Mute Video: Removes the audio track from the video and saves it in the same or a new format.
• Extract Audio: Pulls the audio track out of the video and saves it as an audio file (MP3, AAC, FLAC, etc.).

Both operations are non-destructive — your original file is never modified.

No. MediaConvert works completely offline. All conversions are performed on your local machine. The app does not make any network requests during normal operation.

An internet connection may be needed only once — to initially download and install the app from the Microsoft Store.

Drop the file into the app, then choose Compress Video, Compress Audio, or Compress Image from the operation dropdown, depending on the file type.

A quality slider lets you balance file size against output quality. Lower quality = smaller file size. The estimated output size is shown before you start the conversion so you can adjust accordingly.

Conversion failures can happen for a few reasons:

• Corrupted source file: The input file may be damaged or incompletely downloaded. Try re-downloading or using a backup copy.
• Unsupported codec: Some file containers (e.g., .mkv) may contain video streams encoded with obscure codecs that cannot be decoded on all systems.
• Insufficient disk space: Ensure you have enough free space on the target drive (especially for large, uncompressed outputs like WAV or lossless video).
• File in use: If another application has the source file open with an exclusive lock, MediaConvert may not be able to read it.

The error message shown in the app will indicate the specific error code, which can help narrow down the cause. If you believe it's a bug, please report it.

Open the History tab in the app. You'll find a "Clear History" button that removes all records from the local database (app.db). This only clears the history log — your converted files on disk are not affected.

To completely remove all app data, uninstall MediaConvert via Settings → Apps. Windows MSIX packages clean up their local data automatically on uninstall.
