Una comparativa detallada de PDF Document y Adobe Photoshop Document — tamaño de archivo, calidad, compatibilidad y cuál elegir según tu flujo de trabajo.

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.
Sobre los archivos PSDComparativa de ventajas
PDF Ventajas
- Pixel-perfect fidelity across operating systems, browsers, and printers.
- Embeds fonts, so documents render identically without the reader having them installed.
- Supports digital signatures, encryption, and redaction for legal workflows.
- ISO-standardized (ISO 32000) with multiple validated subsets (PDF/A, PDF/X, PDF/UA).
- Supports both vector and raster content, keeping line art crisp at any zoom level.
PSD Ventajas
- 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.
Limitaciones
PDF Limitaciones
- Editing is difficult — the format is optimized for display, not mutation.
- Text extraction can scramble reading order in multi-column layouts.
- File sizes balloon quickly when embedding high-resolution images or fonts.
- Accessibility (screen readers) requires careful tagging that many PDFs skip.
- JavaScript support has historically been a malware vector.
PSD Limitaciones
- 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.
