Setup: PEF is Pentax's RAW camera format. Goal: an interchangeable TIFF. Turn a PEF image into a TIFF in seconds. The two formats share the same raster DNA so the visible quality is very close; what changes is how the file is packaged, which matters for browsers, editors and CMS uploaders. KaijuConverter runs the conversion server-side and deletes both files within two hours. Worth knowing: PEF is Pentax's RAW camera format. Meanwhile TIFF is the archival multi-page master format used in scanning, print and document pipelines.
Pentax RAW
Source formatPEF is the RAW image format used by Pentax DSLR cameras, containing full sensor data.
TIFF Image
Target formatTIFF is a flexible, high-quality image format widely used in publishing, printing, and professional photography. It supports multiple compression methods and color spaces including CMYK.
Why convert PEF to TIFF
The real reason to move from PEF to TIFF is almost never picture quality — both raster formats store essentially the same pixels. It is about the tools downstream: which editors open the file natively, which CMSes upload it without transcoding, which social platforms accept it. Picking TIFF solves those edge cases at the cost of a short conversion step.
HOW TO CONVERT
PEF → TIFF
Provide the PEF
Click or drag to upload. We accept a single PEF file per job, with an optional queue of additional images for batch mode.
Encode to TIFF
The conversion decodes the PEF, resolves the colour space to sRGB and writes the TIFF container around the pixel data.
Save the TIFF
The download is streamed back over HTTPS. If you uploaded multiple files, a ZIP with all TIFF outputs is produced instead.
Common Use Cases
Document embeds
Word, Google Docs and Pages embed TIFF with correct aspect ratio; PEF may appear as a broken image icon.
Printer-friendly export
Consumer and office printers drive TIFF through their print spoolers with no additional drivers.
Presentation slides
PowerPoint and Keynote treat TIFF as a first-class citizen; PEF may need manual re-insertion per slide.
Online form uploads
Identity verification, job applications and legal forms often list TIFF as the only accepted image format.
PEF vs TIFF — Strengths and limitations
What each format does best, and where it falls short.
PEF Strengths
- Full Pentax sensor data with 14-bit or 12-bit depth.
- Rich Pentax makernotes for lens and filter metadata.
- DNG alternative available on body — user choice of archival openness.
- Every major raw processor supports PEF.
Limitations
- Proprietary with no public spec.
- Niche market share — Pentax DSLR sales are a fraction of Canon/Nikon/Sony.
- Lightroom profile coverage trails the Big Three.
TIFF Strengths
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
Limitations
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.

Quality & Compatibility
PEF-to-TIFF conversion does not change the visible content. Quality is capped by the PEF decode; re-encoding a lossy source at high quality cannot recover detail that was already discarded. For archival masters, keep the original PEF alongside the TIFF copy.
Tips for Best Results
- Large PEF files may look identical to small TIFF files for photographic content; pick quality based on end use, not headline megapixels.
- For print, export TIFF at 300 DPI minimum and check that the colour profile embedded matches the print shop specification.
- Batch-convert related PEF images in one pass so they share identical encoder settings and look consistent side-by-side.
Frequently Asked Questions
Frequently Asked Questions
It depends on the codecs involved. If both PEF and TIFF are lossy, the pixels are re-encoded and a small amount of detail is discarded — invisible at default quality settings on photographs. If TIFF is lossless (PNG, TIFF, BMP) the output keeps every pixel of the decoded PEF exactly, but cannot recover detail that PEF had already compressed away.
Often yes, especially when TIFF is lossless. PEF tuned for efficient web delivery will usually produce smaller files than TIFF's default settings. If file size matters, drop the quality in Advanced or pick a more compressed target format instead.
KaijuConverter uploads over HTTPS, processes the image in an isolated container and deletes both the source and the output within two hours. No account is required, file contents are never logged, and we do not use uploads to train any model. For confidential material, the paid plan includes a data-processing agreement.
