Fast, instant PEF (PENTAX) to TIFF conversion. No signup required. Just drop your .pef file and get .tiff in seconds.
Batch Settings
Some metadata may not survive
Your PEF file may contain MakerNote metadata. TIFF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
デジタルカメラのRAWデータ形式の一つであるPEFファイルは、撮影時の豊かな情報を含んでいますが、汎用性という点では課題があります。特に、印刷業界やプロフェッショナルな画像編集の現場では、その扱いに戸惑うことも少なくありません。そこで、より幅広い環境で利用可能なTIFF形式への変換が重要となります。TIFFは、非圧縮または可逆圧縮による高画質保持能力と、多様な色深度やレイヤー対応の柔軟性から、プロフェッショナルな画像処理において信頼性の高いフォーマットとして広く認識されています。この変換サービスは、お客様の貴重なPEFデータを、品質を損なうことなく、様々な用途で活用できるTIFFへとスムーズに橋渡しします。高精細な画像が求められる場面で、その真価を発揮することでしょう。
- 商業印刷向け入稿
- 漫画・イラストのDTP作業
- ビジネス文書のスキャン保存
日本では、特に縦書きの文書や、文字と画像の組み合わせが重要なデザインにおいて、TIFF形式はフォントの埋め込みや正確なレイアウト保持の面で重宝される傾向があります。
About PEF (PENTAX) to TIFF Conversion
PEF (introduced 2003) and TIFF (introduced 1986) are both image formats, but they differ in important ways. PEF is Pentax's RAW format preserving maximum image data from Pentax SLR sensors. TIFF is an uncompressed or losslessly compressed format favoured in print, publishing, and professional photography.
Full Name: PEF uses Pentax Electronic Format, while TIFF uses Tagged Image File Format. Compression: PEF uses Lossless, while TIFF uses Lossy & Lossless. Transparency: PEF uses No, while TIFF uses Yes.
When you convert PEF to TIFF, the goal is to improve file compatibility across devices. Converting PEF to TIFF maintains high quality with CocoConvert's optimised encoder settings. Understanding these technical differences helps you choose the right format for your workflow.
Your PEF file is decoded and re-encoded as TIFF. The conversion involves 4 steps: (1) your pef file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in tiff format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your PEF file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts TIFF uploads. For the opposite direction, CocoConvert also supports TIFF to PEF conversion.
How to Convert PEF (PENTAX) to TIFF
- 1
Upload .pef file
Select your PEF file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .tiff
Set TIFF as the output format. The converter uses optimal settings based on the PEF→TIFF conversion profile.
- 3
Convert
The server-side engine decodes your PEF file and re-encodes it as TIFF. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .tiff file. Multiple output files can be downloaded together.
What Happens When You Convert PEF (PENTAX) to TIFF
Your PEF image is decoded into raw pixel data, then re-encoded as TIFF.
Your PEF file is decoded — the compressed/stored pixel data is expanded into raw RGB pixels
Pixels are re-encoded using Tagged Image File Format's lossless compression
Metadata (EXIF, ICC profiles) is transferred where TIFF supports it
The TIFF file is saved and ready for download

Does PEF to TIFF conversion affect quality?
Converting PEF to TIFF maintains high quality with CocoConvert's optimised encoder settings.
Which format has better compression, PEF or TIFF?
PEF uses lossless compression. TIFF uses both compression. The better choice depends on whether you prioritize file size or quality.
How long does PEF to TIFF conversion take?
Most conversions finish in seconds. Larger files or complex image content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is PEF or TIFF better for long-term storage?
PEF is better for archival since it's lossless.
