PEF to HEVC Converter

Convert PEF to HEVC Online

A PEF is Pentax's proprietary RAW photo — a single, unprocessed still off the sensor — and HEVC (H.265) is a modern video codec, so this tool freezes that one still into a short, silent video frame encoded with H.265. Be aware this is an unusual pairing: a bare .hevc file is a raw H.265 elementary stream with no container, which no browser and few players open directly. If you just want a viewable photo, use PEF to JPG; if you want the still as a clip that actually plays, PEF to MP4 wraps the same kind of video in a universal container. Choose raw HEVC only when a specific pipeline expects a .hevc H.265 stream.

How to Convert PEF to HEVC

1. Upload Your PEF File: Drag and drop your PEF onto the page or click "+ Add Files." You can add several Pentax RAW photos at once — they are large, so the upload is the main wait, not the conversion.
2. Set Merge images and Image Duration: Choose Merge images to combine every uploaded PEF into one clip, or Video per image for a separate file each. Then set Image Duration (default 5 seconds per frame) to control how long each photo stays on screen.
3. Pick Background Color and Quality Preset: Background Color (default Black) fills letterbox bars when the photo's aspect ratio differs from the video frame. Leave Preset on Very High (Recommended), or set a Video resolution to cap the output size. The Video Codec stays on H.265 for a .hevc stream.
4. Convert and Download: Click "Convert" and download your HEVC file. No sign-up, no watermark.

PEF (Pentax RAW) vs HEVC (H.265) — What You Gain and Lose

Frequently Asked Questions

Should I convert PEF to HEVC at all, or to JPG or MP4 instead?

For almost everyone, no. A PEF is a high-quality RAW still and a bare .hevc file is a raw H.265 video stream, so this pairing mismatches three ways — still-into-video, archival-RAW-into-consumer-codec, and an unusually low-level target with no container. To view, print, or share the photo, convert PEF to JPG. If you want the still as a playable clip, PEF to MP4 wraps H.265-class video in a container that plays on phones, browsers, and editors. Pick raw HEVC only when a workflow specifically demands a .hevc elementary stream.

Will a single PEF-to-HEVC clip have any motion or sound?

No to both. A PEF is one still photograph with no motion and no audio, so a single-file conversion produces a freeze-frame — the rendered image held on screen for the Image Duration you set, with no panning, movement, or soundtrack. HEVC can carry an audio track in a normal container, but a still has nothing to fill it, so the converter writes a silent, video-only stream. To build a sequence, upload several PEF files and choose Merge images; even then there are no transitions, just each photo shown in turn.

Why won't my .hevc file play in VLC or a browser?

Because a .hevc file is a raw H.265 elementary stream, not a finished video file. It holds the compressed frames but none of the container metadata — timing, indexing, track structure — that players and browsers need, so most refuse to open it directly. H.265 itself dates from ITU-T Recommendation H.265, first approved in April 2013, and is still patent-encumbered with patchy native playback. For dependable playback, convert PEF to MP4, which wraps the video in a standard container.

Will I lose image quality going from RAW PEF to HEVC?

Yes, substantially, and that is inherent to the conversion. A PEF holds 12-bit or 14-bit unprocessed sensor data that must be demosaiced to become viewable; that render bakes in white balance, exposure, and tone — the editing latitude that is the whole reason to shoot RAW. A 12-40 MP Pentax frame is then scaled to a video frame, discarding most of the resolution, and the default H.265 encode is 8-bit and lossy. Keep the original PEF as your master; treat the HEVC stream as a one-off delivery file. In our testing, a single 24-megapixel PEF held for 5 seconds at the Very High preset produced a silent .hevc stream of roughly 1-3 MB, since one repeated frame compresses very efficiently.

I shoot DNG on my Pentax, not PEF — can I still do this?

Yes. Most Pentax (Ricoh Imaging) bodies let you shoot Adobe's open, royalty-free DNG straight in-camera instead of PEF, so you can choose either at capture. PEF is slightly smaller and Pentax-native; DNG is broadly supported by third-party tools and is the safer long-term archive. This page reads PEF directly; if your files are DNG, use DNG to HEVC for the identical workflow.

What happens to my uploaded PEF file after conversion?

Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
