Need help?PEF to MPEG-2 Converter
A PEF file is a Pentax Electronic File — the proprietary RAW still that Pentax DSLRs write straight off the sensor, holding far more tonal range than a screen ever shows. MPEG-2 (.mpeg2 / .mpg) is the ISO/IEC 13818-2 video standard behind DVD-Video and digital broadcast. This converter wraps one flattened PEF photo into a short, silent MPEG-2 clip — useful as a source asset for DVD authoring or a video-editing timeline. It does not build an animation, and the output carries no audio.
Is This the Conversion You Want?
PEF is a RAW capture, not a finished picture, and MPEG-2 is a video container — so this is a niche, single-frame-into-video conversion. If you actually want a viewable, shareable photo from your Pentax RAW, convert to a standard image instead:
- Convert PEF to JPG — small, universally viewable photo for sharing and printing.
- Convert PEF to PNG — lossless image when you need crisp edges or transparency.
Choose MPEG-2 only when you specifically need a still on a video timeline — a DVD slideshow source, a leader/hold frame for an editor, or a freeze-frame asset for broadcast-era workflows.

How to Convert PEF to MPEG-2
- Upload Your PEF File: Drag and drop or click "+ Add Files" to add one or more Pentax RAW stills.
- Set Image Duration and Background Color: Pick how long the still holds on screen (default is 5 seconds per frame) and the fill color shown around the frame.
- Choose Quality Preset and Video Resolution: Keep the Very High preset for a clean frame, or set a fixed resolution such as 720×480 if the output feeds a DVD-authoring pipeline.
- Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Will I lose image quality converting a PEF RAW to MPEG-2?
Yes, some range is unavoidably lost. A PEF holds high-bit-depth sensor data, and the conversion demosaics it down to the 8-bit color an MPEG-2 frame can store, then applies lossy video compression. The visible photo can still look good, but the deep highlight and shadow latitude that makes RAW editable does not survive the trip. If you want to keep editing the photo, convert to a high-quality image like TIFF instead.
Why is there no sound in the MPEG-2 file?
A PEF is a still photograph — it contains no audio track. The output is a video that simply displays that one frame for the duration you set, so the resulting MPEG-2 clip is silent by design.
Is the MPEG-2 file a ready-to-burn DVD?
No. A single MPEG-2 stream is an elementary video file, not a DVD. Authoring a playable DVD additionally requires a VIDEO_TS folder structure with IFO/BUP navigation files, built by dedicated DVD-authoring software. This page gives you the MPEG-2 source clip that such software can import.
Why convert to MPEG-2 instead of a modern codec like H.264?
MPEG-2 is older and less efficient than H.264 or HEVC, so for general use a modern codec produces a smaller, cleaner file. The reason to pick MPEG-2 is compatibility with legacy, standards-bound workflows — DVD-Video (defined under ISO/IEC 13818) and some broadcast and disc-authoring tools expect MPEG-2 specifically.
What resolution should I choose for a DVD slideshow source?
For a DVD-Video target, set a fixed resolution of 720×480 for NTSC regions or 720×576 for PAL regions, which match the DVD-Video specification. For a general editing timeline, keep the original resolution or pick the frame size your project uses.
Can I turn several PEF photos into one MPEG-2 video?
Yes. Upload multiple PEF files and use the Merge images strategy to combine them into a single MPEG-2 clip, with each still held for the duration you set. Choose Video per image instead if you want a separate MPEG-2 file generated for each photo.
How long do my files stay on the server?
Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours. Nothing is shared or made public, there is no watermark, and no sign-up is required.
Is PEF the same as DNG, and which one do my Pentax files use?
They are different RAW formats. PEF is Pentax's own proprietary RAW, while DNG is Adobe's open, documented RAW container that Pentax also supports. Many Pentax and Ricoh Imaging DSLRs let you choose in-camera whether to record PEF or DNG, so your files could be either — check the extension. This page is for .pef input; if your Pentax RAWs are .dng, use the DNG converter instead. Whichever you shoot, converting to MPEG-2 flattens the RAW to 8-bit video, so keep the original for any real editing.
