QT is commonly used for legacy QuickTime playback and editing workflows. MP4 is a practical output for widely compatible playback, sharing, and web delivery.
Changing containers or codecs can affect file size, compatibility, and quality. Compatible MP4 codec choices are H.264, H.265 / HEVC, and AV1.
Process an occasional batch without a watermark or account. Create a free account to save one setup as a recipe, or upgrade for more recipes and automatic delivery to Google Drive or Dropbox.
A QT file can contain older QuickTime media that a browser, phone, or upload service does not handle directly. MP4 is a practical delivery choice for those destinations. The conversion creates a new video file; it does not require the recipient to install an old QuickTime application.
Use this page for .qt sources. If your QuickTime file ends in .mov, use MOV to MP4 so the upload filter matches the file. The extension describes the container rather than the full encoding inside it.
QuickTime containers can hold many kinds of media. A damaged recording or an unsupported source stream may fail even when the filename is accepted. Start with one representative file from each source.
A delivery MP4 may use different compression and track handling from the QT original. Retain the source when additional audio tracks, future editing, or archival fidelity matter to the project.
Use Recommended MP4 output at the original dimensions. Verify audio sync, duration, and playback in the target browser or application, then save those settings for subsequent QT batches from the same archive.
