Raster & Vector Images

PNG is a lossless image format that supports transparency. It is ideal for graphics, logos, screenshots, and any image where preserving exact pixel data is important.

About PNG files

Strengths Comparison

M4V Strengths

Fully MP4-compatible — one-line rename to .mp4 in most workflows.
First-class support across Apple devices (macOS, iOS, tvOS, HomePod video).
Supports chapters, closed captions, and multi-language audio tracks.
Can hold Dolby Vision and HDR10+ metadata.

PNG Strengths

Lossless compression — every save preserves the original pixels perfectly.
Full 8-bit alpha channel for smooth transparency.
Excellent for text, UI screenshots, logos, and line art.
Royalty-free and an ISO standard (ISO/IEC 15948).
Supports 16-bit color depth for high-fidelity work.

Limitations

M4V Limitations

FairPlay DRM variants tie files to Apple IDs — moves to other ecosystems break playback.
Extension is not strictly standardized — some tools flag it as unknown.
Rarely used outside Apple distribution.

PNG Limitations

Much larger than JPEG for photographs (no perceptual compression).
No native animation in most software (APNG support is inconsistent).
No CMYK support — web and screen only, not print.
Metadata capabilities are less rich than JPEG's EXIF.

Frequently Asked Questions

M4V (M4V Video (Apple)) is a video container format that bundles one or more video streams, audio tracks, and optional subtitles into a single file. The container format determines how metadata is organised and which codecs can live inside; the visual quality itself depends on the codec (H.264, H.265, VP9, AV1) rather than the M4V wrapper. It is part of the video files family.

Upload your M4V to KaijuConverter and pick MP4, MOV, MKV, WebM, or any other target. Our pipeline uses FFmpeg under the hood and stream-copies when codecs are compatible (no quality loss) or transcodes at high-quality defaults otherwise. Conversion runs server-side; both files delete within two hours.

Only when the target requires re-encoding. If the codecs inside M4V match what the target container supports, FFmpeg stream-copies the streams and the output is bit-identical to the source. Transcoding uses transparent quality defaults (CRF 20–23 H.264) and produces output indistinguishable from the original at normal viewing distance.
