Convert MOV to MP4 — Offline
Drop one or more Apple QuickTime .mov files onto MiniMax Converter and get standard .mp4 (H.264 video, AAC audio) that plays everywhere. Choose a quality level, use your GPU encoder if you have one, and batch a whole folder at once. Everything runs locally — no upload, no file-size limit, no watermark.
How to convert
- Drag your .mov file (or a folder of them) onto the MiniMax Converter window.
- Pick MP4 as the output format from the format chooser.
- Set the quality slider (lower CRF = higher quality, larger file) and, if your machine has one, enable hardware H.264 encoding for a faster run.
- Click convert and choose where to save; the finished .mp4 files land in the folder you pick.
What you get out
Output is a standard .mp4 container with H.264 video and AAC audio — the combination that plays on phones, browsers, TVs, and editors without extra codecs. MOV and MP4 are both wrappers, and many MOV files already hold H.264/AAC inside, so the picture and sound you get are visually the same as the source at sensible quality settings. Re-encoding video is lossy by nature, so keeping the quality slider near the default avoids any visible degradation.
Why MOV → MP4 at all
QuickTime .mov files from iPhones, screen recorders, and cameras play fine on a Mac but can stumble on Windows players, older TVs, web uploads, and some editing tools. Converting to .mp4 gives you the most universally accepted video container. You control the trade-off with the quality slider — a lower CRF keeps detail at the cost of file size, a higher one shrinks the file, and the hardware encoder option speeds up large batches on supported GPUs (NVENC, AMF, QSV, VAAPI, or VideoToolbox).
Why offline?
Online MOV-to-MP4 converters cap file sizes, throttle upload speed, queue you behind other users, and frequently stamp a watermark or run ads. Phone-camera MOV files are often multiple gigabytes, so they hit those caps immediately. Local conversion handles any size at the speed of your own CPU or GPU, and your footage never leaves your machine — nothing is uploaded and nothing is logged.
Questions and answers
Is converting MOV to MP4 lossless?
Not exactly. MiniMax Converter re-encodes the video to H.264, which is a lossy step, but at the default quality setting the result is visually indistinguishable from the source for normal footage. If you want the smallest possible quality loss, move the quality slider toward the higher-quality (lower CRF) end.
Will it work on large MOV files (several GB)?
Yes — there is no file-size cap. ffmpeg processes the file in a streaming fashion, so memory use stays low regardless of how long or large the video is. iPhone and screen-recording MOV files of many gigabytes convert without issue.
Can I convert a whole folder of MOV files at once?
Yes. Drop multiple files or a folder and they are queued as a batch and processed in parallel, using multiple CPU cores so a folder of clips finishes faster than converting them one by one.
Will the converted MP4 keep the original audio and resolution?
Yes. The resolution is preserved and the audio track is carried over as AAC. Frame rate and dimensions stay the same as the source; only the codec and container change so the file plays on more devices.
