PSD vs XPM
Ein detaillierter Vergleich von Adobe Photoshop Document und X PixMap — Dateigröße, Qualität, Kompatibilität und welches je nach Workflow zu wählen ist.
Adobe Photoshop Document
Raster & Vector ImagesPSD is the native file format for Adobe Photoshop, storing layered image data, masks, color spaces, and editing metadata. Converting PSD flattens layers into a single composite image.

Über XPM-DateienVorteilsvergleich
PSD Vorteile
- Preserves every Photoshop feature: layers, masks, adjustments, smart objects, text, effects, styles.
- Backward-compatible — files from 1990 still open in modern Photoshop.
- Industry-standard handoff format between designers, agencies, and prepress.
- Supports 32-bit HDR, CMYK, Lab, Duotone, and spot colors for professional print work.
- Rich metadata, color profiles, and printing instructions survive round-trips.
XPM Vorteile
- Valid C source — directly embeddable in code.
- Text-editable in any editor.
- Transparency via "None" color value.
- Stable since 1989 with no breaking changes.
Einschränkungen
PSD Einschränkungen
- Proprietary — full fidelity only in Adobe tools; other apps approximate.
- File sizes are enormous (hundreds of MB is common for complex documents).
- Not a web format — browsers cannot display PSD natively.
- Binary structure is complex and version-dependent; parsers often lag the latest Photoshop version.
- Hard 2 GB / 30 000 px limit forces professionals to switch to .psb for large artwork.
XPM Einschränkungen
- Enormous file sizes vs compressed formats.
- Only useful within X11 / legacy Unix GUI ecosystem.
- Limited color palette in classic form (256 colors max practical).
- Superseded by PNG and SVG for modern UI.
