Quality & Fidelity
Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the MP4 Video format supports it. Format-exclusive metadata fields that have no equivalent in MP4 Video are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality M4V Video input produces an excellent MP4 Video output. Xonvert defaults to high quality settings that keep file size reasonable without compromising perceivable quality. M4V Video encodes data using perceptual compression that prioritizes human perception. MP4 Video similarly focuses on perceptual quality. The conversion maps between these approaches intelligently.
Video format conversion from M4V Video to MP4 Video involves re-encoding or remuxing the video stream. Xonvert selects the most efficient encoding strategy — remuxing when possible (zero quality loss) and re-encoding with optimal parameters when the target format requires a different codec. Key factors include codec compatibility, resolution handling, and audio stream preservation.
Resolution handling: Your video's original resolution is preserved by default. You can optionally downscale in the settings panel to reduce file size — useful when preparing content for mobile viewing or web upload.

Got Questions? We Have Answers
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose MP4 over other formats?▼
MP4 Video offers universal playback support with efficient H.264/H.265 compression. It's widely used for streaming, social media, web video and general-purpose video, making it an excellent choice for most video needs.
Will my M4V file be deleted after conversion?▼
No. Your original M4V file is never modified or deleted. Xonvert creates a separate MP4 copy — your source file remains untouched.
What video quality settings should I use?▼
For archival, use High quality. For social media sharing, Medium provides great results at smaller file sizes. Adjust bitrate for fine control.
Does this work on my phone or tablet?▼
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
Can I undo a conversion?▼
Since your original M4V file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new MP4 copy is created.
What if my M4V file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
