Tool guide
Free Online MOV to MP4 Converter
Convert one Apple QuickTime MOV file into MP4 in your browser. Formatza first tries to copy compatible streams and falls back to H.264 video with AAC audio when the MOV codecs need conversion.
Steps
How it works
- Choose one MOV file up to 250 MB.
- Preview the source where your browser supports its QuickTime codecs.
- Start conversion so FFmpeg can copy compatible streams or re-encode unsupported ones.
- Preview the MP4 result and download the generated file.
Highlights
Key features
- Converts a MOV container into a real MP4 file.
- Attempts stream copy before using H.264/AAC fallback encoding.
- Adds fast-start metadata to the MP4 output.
- Shows a warning that some MOV codecs may not decode in the browser FFmpeg build.
- Provides processing progress, output preview, output size, and direct download.
Use cases
Common uses
- Convert an iPhone, Apple, or QuickTime-style MOV for an MP4 workflow.
- Prepare MOV footage for a player or upload form that prefers MP4.
- Create a sharing copy of a MOV recording.
- Use a MOV clip in software with broader MP4 support.
Notes
Limitations to know
- The converter handles one MOV at a time and does not provide batch, bulk, or ZIP conversion.
- MOV is a container and can hold many codecs; some professional, legacy, or Apple-specific codecs may fail to decode.
- Fallback re-encoding can change visual quality, audio quality, frame handling, and file size.
- Alpha transparency, professional editing metadata, and all container metadata are not guaranteed to survive.
- MP4 is widely used but universal playback or editor compatibility cannot be guaranteed.
FAQ
Frequently asked questions
Does MOV to MP4 always re-encode the video?
No. The tool first attempts stream copy. If the existing streams cannot be written to MP4, it falls back to H.264 video and AAC audio.
Why does one MOV work while another fails?
MOV files can contain different video and audio codecs. Some codecs are not available in the browser FFmpeg build even though the file extension is valid.
Will audio be preserved?
Compatible audio may be copied; fallback conversion encodes audio as AAC. Unsupported audio streams can still prevent a successful result.
Will transparency and editing metadata remain?
They are not guaranteed. Common H.264 MP4 output does not preserve alpha transparency, and specialized MOV metadata may be removed or changed.
Can I convert multiple MOV files together?
No. This tool currently accepts one MOV file at a time, up to 250 MB.
