RW2 to HEVC Converter

Convert RW2 to HEVC Online

An RW2 is a Panasonic LUMIX RAW photo — a single, high-bit-depth still off the sensor — and .hevc is a raw H.265 video elementary stream, the bare bitstream a video encoder emits before it is wrapped in a container. This tool renders your RAW into one picture and writes it as a short, silent HEVC clip holding that single frame. Be warned this is an unusual target: a bare .hevc file won't open in most players. Most people landing here actually want a normal photo — use RW2 to JPG — and if you want the still as a playable video, RW2 to MP4 wraps the same H.265 in a container that phones, browsers, and editors can open.

How to Convert RW2 to HEVC

1. Upload Your RW2 File: Drag and drop your .rw2 onto the page or click "+ Add Files". RAW files are large, so the main wait is the upload, not the conversion; you can queue several at once.
2. Set Merge Strategy and Image Duration: Choose Merge images to combine several RW2 stills into one HEVC stream, or Video per image for a separate file each. Set Image Duration (default 5 seconds per frame) for how long the photo is held on screen.
3. Pick Background Color and Quality Preset: Background Color (default Black) fills the letterbox bars when your photo's aspect ratio differs from the video frame. Leave Quality Preset on Very High (Recommended), or set a Video resolution preset to cap the output size.
4. Convert and Download: Click "Convert" and download your HEVC file. No sign-up, no watermark. The output is silent by design — the video codec defaults to H.265.

RW2 vs the HEVC Output — What You Gain and Lose

Frequently Asked Questions

Why does converting one RW2 to HEVC give me a silent, motionless clip?

Because an RW2 is a single photograph, not footage — there's no timeline, movement, or audio inside it. Converting one RW2 yields a freeze-frame: the rendered image held for the Image Duration you set, with no panning, no animation, and no sound. HEVC can carry audio when it's muxed into a container alongside an audio track, but a single still has nothing to supply one, so the converter encodes image sources silent. To build a sequence that actually changes over time, upload several RW2 files and choose Merge images.

Why won't my .hevc file play in VLC or my media player?

A bare .hevc is a raw H.265 elementary stream — just the encoded video bitstream, with no container, no timing index, and no audio track. Most players, including VLC, expect a container (MP4, MKV, MOV, TS) and refuse a raw stream or play it unreliably. You'd have to remux it into a container first (for example with ffmpeg's stream-copy). That's exactly why, for a still you want to actually watch, RW2 to MP4 is the better choice — it wraps the same H.265 video in an MP4 that plays on phones, browsers, and editors without an extra step.

Will I lose image quality going from a RAW RW2 to HEVC?

Yes, substantially, and it's inherent to the conversion rather than a tool flaw. An RW2 stores 12- or 14-bit, unprocessed sensor data that must be demosaiced and tone-mapped to become viewable; that render bakes in white balance, exposure, and color, so the RAW latitude — the whole reason to shoot RW2 — is gone once it's a video frame. On top of that, a roughly 12-47 MP RAW is scaled down to a video frame (standard-definition-to-1080p class), discarding most of the resolution, and H.265 is a lossy codec. Always keep the master RW2 — the HEVC stream is a throwaway delivery file, not an archive.

What exactly is HEVC, and is it the right target for a single photo?

HEVC (High Efficiency Video Coding, also called H.265 and MPEG-H Part 2) is a video compression standard the ITU-T and ISO/IEC jointly approved in 2013, designed to deliver roughly the same quality as H.264 at about half the bitrate. It's a video codec, so it's an odd home for one still: you gain little from H.265's motion-compression strengths on a frozen frame, and the bare .hevc extension means most software can't open the result. Pick this only if a specific H.265 toolchain explicitly wants a raw elementary stream. For viewing or sharing the photo, RW2 to JPG is the right answer; for a playable clip, RW2 to MP4 wraps H.265 (or H.264) in a container that plays everywhere.

What happens to my uploaded RW2 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. In our testing, a single 20-megapixel RW2 converted at the default 5-second duration produced a short, silent H.265 stream that played only after we muxed it into an MP4 container — confirming a raw .hevc file needs a container before most players will open it.
