ORF to HEVC Converter

Convert ORF to HEVC Online

This tool renders an ORF (Olympus RAW Format) photo and wraps it in HEVC — the H.265 codec — as a short, silent clip that holds the single still on screen. Be clear-eyed before you start: an ORF is one archival camera RAW still, and a bare .hevc file is a raw H.265 elementary stream with no container, so most players will not open it without first muxing it into MP4 or MKV. If you only want a normal, viewable photo, convert ORF to JPG or ORF to PNG instead; if you genuinely need the still as a clip, ORF to MP4 writes H.264 that plays everywhere and is a far safer target than a raw HEVC stream.

How to Convert ORF to HEVC

1. Upload Your ORF File: Drag and drop your ORF onto the page or click "+ Add Files". RAW files are large, so the main wait is the upload, not the conversion; you can add several ORFs at once.
2. Set Merge strategy and Image Duration: Choose Merge images to combine every uploaded ORF into one HEVC clip, or Video per image for a separate file each. Set 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 any letterbox bars when your photo's shape differs from the video frame. Leave Quality Preset on Very High (Recommended), or set a Video Resolution preset to cap the output size. The Video Codec menu defaults to H.265 for .hevc output.
4. Convert and Download: Click "Convert" and download your HEVC file. The clip is silent — an image source has no audio, so the converter writes no audio track. No sign-up, no watermark.

HEVC vs MP4 (H.264) as a Target for a Single Photo

Frequently Asked Questions

Should I convert ORF to HEVC, or to MP4 or JPG instead?

For almost every purpose, no — HEVC is an odd target for a single still. This pairing mismatches three ways: an archival camera RAW still, frozen into video, wrapped in a raw H.265 stream that most players cannot open without muxing. HEVC earns its ~50% size advantage on real motion footage; a static one-frame clip gives it nothing to compress, so you pay the slow-encode and playback cost for no real gain. If you want to view, print, or share the photo, convert ORF to JPG or ORF to PNG. If you truly need the still as a clip, ORF to MP4 writes H.264 that plays on phones, browsers, and editors with the fewest surprises.

Why won't my .hevc file open in VLC or QuickTime?

Because a bare .hevc is a raw H.265 elementary stream — just the encoded video with no container around it. Most players expect the stream wrapped in MP4, MOV, or MKV, which carry the timing and track metadata they need, so a naked .hevc often refuses to open or shows nothing. To make it playable you would mux it into a container (for example with ffmpeg, copying the stream without re-encoding). If you want a file that simply plays, skip the raw stream and convert ORF to MP4 instead.

Why does my ORF-to-HEVC output have no sound?

Because a still photo contains no audio data, so the clip is video-only by design. When the source is an image, the converter hides the audio codec entirely and writes no audio stream — there is nothing in a single ORF to fill one. If you want music or narration, convert first, then add an audio track in any video editor.

Will I lose image quality going from a RAW ORF to HEVC?

Yes, substantially, and that is inherent to the conversion rather than a tool flaw. An ORF holds undemosaiced, higher-bit-depth sensor data — 12-bit on most Olympus bodies, 14-bit on later OM-D models — that must be demosaiced and tone-mapped to become viewable. That render bakes in white balance, exposure, and tone, so the RAW latitude that is the whole reason to shoot RAW is gone once it is a video frame. A roughly 10-20 MP Four Thirds or Micro Four Thirds RAW is then scaled down to a video frame, discarding most of the resolution. In our testing, a 16-megapixel ORF wrapped at the Very High preset produced a short, silent H.265 clip at 1080p — sharp on screen, but a fraction of the original pixel count. Keep the original ORF for any future editing; the HEVC file is a delivery file, not an archive.

Is ORF a proprietary Olympus format, and does that affect the conversion?

ORF is the proprietary Olympus RAW Format, introduced with the Olympus E-10 in 2000 and written by Olympus and OM SYSTEM (OM Digital Solutions since January 2021) cameras such as the OM-D, PEN, Tough, and E-system bodies, all built on Four Thirds and Micro Four Thirds sensors. It is a TIFF/EP-based container holding Bayer sensor data that must be demosaiced to view. Because the conversion happens on our servers, you do not need OM SYSTEM Workspace or any RAW plugin installed — upload the .orf straight from the card. Note that very new camera models can take time to be supported by any third-party RAW decoder.

What happens to my uploaded ORF 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.
