Convert PEF to TIFF — Free Online Converter

TIFF is the gold standard for archival-quality image storage, and converting Pentax PEF RAW files to TIFF produces the highest-quality output available in a universally supported format. The Pentax K-1 II's 14-bit full-frame sensor and the K-3 III's 12-bit APS-C sensor both capture exceptional tonal depth that TIFF can preserve at 16-bit per channel — maintaining every nuance of the original capture.

Pentax DSLRs have long been favored by photographers who value image quality above all else. The combination of Pentax's sharp optics (particularly the Limited prime series and the D FA* pro lenses) with the K-1 II's full-frame sensor produces files that demand a quality-preserving output format. TIFF delivers exactly that.

While PEF files offer full RAW editing flexibility, they require Pentax-specific or RAW-aware software to open. TIFF provides the quality benefits of a lossless format with universal application support. Every professional image editor, print service, and archival system accepts TIFF without any special codecs or plugins.

For print workflows, TIFF is the industry standard. Fine art printers, publishing houses, and commercial print shops all work with TIFF natively. The K-1 II's 36 MP sensor provides exceptional resolution for large-format printing, and TIFF preserves every bit of that resolution and tonal depth through to the final print.

The PEF's 12-14 bit Bayer data is demosaiced into full-color RGB and saved as TIFF with LZW or ZIP lossless compression. At 16-bit per channel, the K-1 II's full 14-bit dynamic range is preserved with headroom. A 36 MP K-1 II image produces a 16-bit TIFF of approximately 140-200 MB (with lossless compression). EXIF metadata including Pentax camera model, lens identification, and shooting parameters is embedded in TIFF IFD tags.
