Checking for an available MOV to MP4 worker
Each valid QuickTime video starts an independent upload and conversion job. MOV and MP4 are fixed for this page.
Make a compatible MP4 from a QuickTime MOV
Use this converter for genuine QuickTime MOV videos from iPhone, QuickTime, Mac screen recordings, cameras, and editing exports when an app or device needs MP4. Files are inspected as QuickTime containers; changing a filename extension does not turn an MP4 or audio-only file into a valid MOV video.
Select one or more files up to 1 GB each. Every valid file starts its own conversion job immediately, with separate upload progress, conversion status, download, error, retry, and delete actions.
MOV and MP4 are different containers
MOV is the QuickTime container and MP4 is a distinct ISO Base Media File Format container. The worker accepts QuickTime's 'qt ' major brand and rejects MP4- or M4A-branded files even if renamed to .mov. A QuickTime MOV may carry video and audio streams that are not ready to use unchanged in an MP4.
When its streams are compatible, the converter remuxes the MOV into MP4 only after checking the resulting stream metadata, duration, and display properties. This avoids an unnecessary decode-and-reencode pass and generation loss; if verification fails, supported video is encoded to H.264 with yuv420p pixel format and source audio to AAC at 128 kbps when present. A conversion that cannot preserve the required video and audio streams fails visibly instead of silently dropping them.
Picture dimensions, orientation, and frame rate
The fallback encode keeps the source resolution and aspect ratio, uses the source frame rate and duration, and does not trim the clip. Rotation or display-orientation metadata is retained so a portrait recording is not needlessly presented sideways.
The fallback video encode uses H.264 CRF 23 at the medium preset in yuv420p. Source audio, when present, uses AAC at 128 kbps. This page applies those fixed defaults automatically; it does not provide trim, codec, quality, resize, or frame-rate controls.
Separate jobs and file handling
Each selected MOV has its own worker selection, upload, progress, and result. One failed file does not change another file's job. The browser receives signed progress and download access; use the delete action on a completed job to remove its uploaded and converted files from the worker.
Uploads are limited to 1 GB per file. If a file is larger, reduce its size outside this converter before uploading it.
How to convert MOV to MP4 online
- Choose one or more genuine QuickTime MOV videos, up to 1 GB each.
- Each valid file starts its own MOV to MP4 job after a compatible worker is found; there is no output-format or quality menu to configure.
- Follow each file's upload and conversion progress. A failed file shows its own error and can be retried.
- Download the signed MP4 when it is ready, or use the delete action to remove the uploaded and converted files from the worker.
MOV to MP4 FAQ
Is a MOV file just an MP4 with a different extension?
No. MOV is a QuickTime container and MP4 is a different container. The worker requires the QuickTime 'qt ' major brand and usable video; renaming an MP4, M4A, or other file to .mov does not make it a valid MOV.
Will MOV to MP4 conversion recompress my video?
Verified compatible H.264 yuv420p video with AAC or MP3 audio can be remuxed without recompression. Other supported video uses the fixed H.264 yuv420p fallback at CRF 23 and the medium preset; source audio, when present, uses AAC at 128 kbps.
Will the MP4 keep the MOV's size, orientation, and frame rate?
The fallback keeps the source resolution and aspect ratio and uses the source frame rate and duration without trimming. Rotation or display-orientation metadata is preserved. Compatible streams that are remuxed keep their original encoded dimensions and frame rate.
Can I change codec, quality, trim, size, or frame rate?
No. This page uses a fixed MOV to MP4 workflow. It does not expose trim, codec, quality, resize, or frame-rate controls; supported fallback video encodes use full-resolution H.264 yuv420p CRF 23 at medium, and source audio, when present, uses AAC at 128 kbps.
How large can a MOV upload be?
Each MOV file can be up to 1 GB. If it is larger, reduce its size outside this converter and then upload the smaller file.
Can I convert several MOV videos at once?
Yes. Select multiple files and each valid MOV starts an independent job with its own progress, result, error, retry, and download. The 1 GB limit applies to each file.
What happens to a MOV file without usable video?
The upload is rejected or the job reports a conversion error. Renamed MP4 and audio-only files are not accepted as QuickTime MOV video. Required video or audio streams are not silently discarded.
Can I remove my uploaded files after conversion?
Yes. Use the delete action on a completed job to remove its uploaded source and converted MP4 from the worker.
