About formats

PEF (Pentax Electronic Format) is the proprietary RAW image format used by Pentax digital SLR and mirrorless cameras, introduced in 2003 with the *ist D — Pentax's first digital SLR — and continuing through the current K-mount and medium-format 645 lineup. PEF files capture the unprocessed 12-bit or 14-bit readout from the camera's CMOS sensor in its native Bayer mosaic pattern, stored in a TIFF-based container with Huffman-coded lossless compression. The format includes embedded JPEG previews at multiple sizes, comprehensive EXIF metadata, and Pentax-specific MakerNote tags that record Custom Image mode settings, Shake Reduction (SR) gyroscope data, lens identification from the K-mount electronic interface, and the camera's Auto Level correction parameters. Pentax cameras are notable for their weather-sealed construction and compatibility with the vast legacy of K-mount lenses dating back to 1975, and PEF files from these bodies can include manual lens metadata entered through the camera's menu system. One advantage is the preservation of Pentax's distinctive color rendering — the brand's Custom Image modes (Bright, Natural, Reversal Film, Bleach Bypass, etc.) are stored as metadata rather than applied to the raw data, allowing photographers to explore different rendering interpretations during post-processing while the original sensor capture remains untouched. The format's longevity is another strength: PEF files from every Pentax DSLR are supported by Adobe Lightroom, Capture One, dcraw, RawTherapee, Pentax's own Digital Camera Utility, and other modern RAW processors.

VIPS is the native file format of the libvips) image processing library, originally developed by John Cupitt and Kirk Martinez at the National Gallery in London during the VASARI project (1989-1993) for high-resolution digitization and analysis of paintings. The VIPS format stores large images in a simple, memory-mappable layout: a header containing image dimensions, number of bands (channels), data type (8/16/32-bit integer, float, double, complex), color interpretation, resolution, and offset metadata, followed by the raw pixel data in band-interleaved format. This straightforward layout allows the operating system's virtual memory manager to map the file directly into address space, enabling libvips to process images much larger than available RAM by paging portions in and out as needed — a technique called demand-driven evaluation. VIPS files support images with any number of bands at any of the supported numeric types, accommodating everything from standard RGB photographs to hyperspectral datasets with hundreds of bands. One advantage is large-image performance: libvips's architecture processes images in small tiles evaluated on demand, meaning a 100,000 x 100,000 pixel image can be cropped, resized, sharpened, and saved without loading the entire image into memory — a capability that makes VIPS the engine behind image processing services handling millions of web images. The format's scientific heritage is another strength — the VASARI project required analyzing paintings at ultra-high resolution with multispectral imaging, and the VIPS format's support for arbitrary band counts and floating-point precision reflects these computational imaging origins. VIPS files are primarily used with the libvips library (available for C, Python, Ruby, and other languages) and can be converted to other formats via vips command-line tools or ImageMagick.
Initial release: 1993

Frequently Asked Questions

Why should I convert PEF to VIPS?

Pentax's PEF format preserves maximum image detail for editing but needs conversion to VIPS for practical use in presentations, websites, or prints.

What applications work with VIPS?

VIPS works with libvips tools, nip2, and VIPS-compatible image processing pipelines.

Does converting PEF to VIPS affect quality?

Your PEF image data is processed carefully during conversion. The resulting VIPS retains the maximum quality the target format can support.

Is my PEF file safe during conversion?

Security is built in. Uploaded PEF images are removed immediately after conversion, and VIPS files are automatically cleaned up within 24 hours.

How long are converted files stored?

Converted VIPS files remain available for download for up to 24 hours, after which they are automatically deleted from Convertio servers.

Is PEF to VIPS conversion free?

Yes — basic PEF to VIPS conversion is free. If you need to process larger batches or bigger files, premium options are available.
