mov to mp4 without losing quality
Converting between video formats always involves some re-encoding, but the visible quality difference can range from imperceptible to noticeable depending on the settings used. This page covers getting the closest possible match to your original MOV file's quality.

The CRF slider is the setting that matters most here. Values between 18 and 20 stay very close to source quality — noticeably better than the default of 20, and a meaningful step up from the 24+ range that's fine for casual sharing but starts showing more compression in detailed or fast-moving footage.
The medium preset generally produces better quality-per-kilobyte than the faster presets at the same CRF value, since it spends more encoding time finding efficient ways to represent each frame. If you have a moment to let it process, medium at a low CRF is the closest you'll get to a visually lossless-feeling conversion.
It's worth knowing that if your original MOV file used HEVC (H.265), it was already fairly efficiently compressed — converting to H.264 MP4 at an equivalent visual quality will typically produce a somewhat larger file than the HEVC original, since H.264 needs more data to achieve the same visual result. This isn't a quality loss, just a difference in how efficiently each codec compresses the same visual information.
After converting, compare a still frame or a few seconds of playback side by side with the original if quality is critical — for most everyday recordings, a CRF of 18–20 on the medium preset is close enough to the source that you won't notice a practical difference.
Top benefits
- Get the closest practical match to your original MOV file's visual quality.
- Understand why an HEVC-to-H.264 conversion can end up larger without meaning quality was lost.
- Use the medium preset for better quality-per-kilobyte than the faster options.
How to apply this keyword workflow
- Upload your MOV file.
- Set CRF to 18–20 for the closest match to source quality.
- Choose the medium preset for better encoding efficiency.
- Download and compare the result against the original if quality is critical.
Best use cases
- Converting an important recording where visual quality needs to stay close to the original.
- Preparing footage for further editing, where starting quality matters.
- Archiving MOV recordings in a more universally compatible format without a visible quality hit.

FAQ
What CRF value keeps the best quality for MOV to MP4?
18–20 on the medium preset stays closest to the original. The default of 20 is already a reasonable balance; going lower trades file size for a smaller quality margin.
Why is my converted MP4 larger than the original MOV?
If the MOV used HEVC (H.265), it was already efficiently compressed. Converting to H.264 MP4 at similar visual quality typically needs more data, since H.264 is a less efficient codec — this isn't a quality loss, just a difference in compression efficiency.
Does the preset affect quality?
Indirectly — medium generally achieves better quality at the same CRF than faster presets, because it spends more time finding efficient per-frame encoding decisions.
Is my MOV file uploaded to a server?
No. Conversion runs entirely in your browser using FFmpeg WebAssembly.
How can I check if the conversion kept enough quality?
Compare a few seconds of playback or a still frame side by side with the original MOV, focusing on detailed or fast-moving sections where compression artifacts show up first.
