Convert MP4 to QT in batches online for workflows that request a QuickTime .qt file. Choose compatible video settings. Free, no sign-up or watermark.
MP4 is commonly used for widely compatible playback, sharing, and web delivery. QT is a practical output for legacy QuickTime playback and editing workflows.
Changing containers or codecs can affect file size, compatibility, and quality. Compatible QT codec choices are H.264, H.265 / HEVC, and Apple ProRes.
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.
QT is a filename extension associated with the QuickTime container family, which also includes MOV. Convert MP4 to QT when an older application or delivery specification explicitly requests a .qt file. If you only want to watch an MP4 in a modern QuickTime player, conversion may be unnecessary.
The receiving application must support the video and audio streams inside the container. Check codec requirements as well as the filename extension, especially when delivering to an older version of an editing tool.
Some workflows ask for QuickTime but actually expect a .mov filename. Use the MP4 to MOV converter for that requirement instead of creating a QT file that the upload form may reject.
FastConvert applies the chosen encoding settings. Treat the output as a new delivery file, keep the MP4 master, and compare quality rather than assuming the conversion only renames or repackages the source.
Begin with Recommended settings and source-like dimensions. Test the QT file in the exact application that requested it. For recurring deliveries, save the working codec and quality choices as a recipe after this compatibility check.
