Preguntas frecuentes
PEF (Pentax RAW) 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 PEF when its particular strengths match the publishing target.

Most desktop photo viewers (Windows Photos, macOS Preview, GIMP, Photoshop, Affinity Photo) open PEF natively. On mobile, iOS Photos and Google Photos display PEF 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 PEF to JPG or PEF to PNG converter.

It depends on the task. JPG is the smallest file size for photographs; PNG is lossless with transparency; PEF 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.
