DPX vs PNG
Ein detaillierter Vergleich von Digital Moving-Picture und PNG Image — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
Digital Moving-Picture
Raster & Vector ImagesDPX (Digital Picture Exchange) is a SMPTE standard file format for digital intermediate and visual effects work. It stores per-frame image data with rich metadata for color management and is widely used in film post-production pipelines.
Über DPX-DateienPNG Image
Raster & Vector ImagesPNG 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.
Über PNG-DateienVorteilsvergleich
DPX Vorteile
- Industry-standard archival format for film.
- Logarithmic color encoding preserves film look.
- Lossless — no generation degradation.
- SMPTE standardized (SMPTE 268M).
- Every VFX and color-grading app reads and writes DPX.
PNG Vorteile
- 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.
Einschränkungen
DPX Einschränkungen
- No compression — file sizes are enormous.
- Not a display format — requires color-managed pipelines.
- Gradually superseded by OpenEXR in modern VFX.
- Overkill for anything but professional film work.
PNG Einschränkungen
- 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.

Häufig gestellte Fragen
DPX (Digital Moving-Picture) is an image format used to store raster graphics — a two-dimensional grid of pixels describing a picture. It is part of the raster & vector images family and designed around a specific trade-off between file size, visual fidelity, and feature support (transparency, colour depth, compression type). Photographers, web designers, and content creators choose DPX when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open DPX natively. On mobile, iOS Photos and Google Photos display DPX in the gallery when supported by the OS. If the format is rare or new, convert to JPG or PNG first — both are universally readable — using our DPX to JPG or DPX to PNG converter.

Upload the DPX to KaijuConverter and pick a target format (JPG, PNG, WebP, HEIC, TIFF, BMP, SVG, PDF). The conversion runs in the browser via ImageMagick and returns a download in seconds. No account or installation required; both input and output delete automatically within two hours.
It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; DPX has its own niche that may favour colour depth, animation, or encoding efficiency over one or both of those. For the final web publish, test all three and measure file size plus visible quality on real content.
