Need help?CRW to AV1 Converter
CRW is Canon's original RAW photo format — a single still image straight off an early Canon sensor. AV1 is a modern royalty-free video codec. So this is a still-to-video conversion: your CRW becomes a short, silent video clip that holds that one frame for a set duration. If you actually want a photo, convert CRW to JPG or CRW to TIFF instead — this tool is for turning a still into a clip (a slide, a placeholder shot, or a frame to splice into a timeline).

How to Convert CRW to AV1
- Upload Your CRW File: Drag and drop your CRW onto the page or click "+ Add Files." You can add several at once.
- Set Image Duration and Merge Strategy: Use the "Duration" dropdown to pick how long the frame holds (default 5 seconds per frame). Choose "Merge images" to combine multiple stills into one clip, or "Video per image" for a separate clip per file.
- Pick Quality Preset and Resolution: Set the "Preset" (e.g. Very High) under Quality Preset, and choose a Preset Resolution or keep the original under Video resolution. Set a Background Color if the frame is letterboxed.
- Convert and Download: Click "Convert" to get your AV1 stream. 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 my CRW photo have audio in the AV1 file?
No. A CRW is a still image with no sound, and the output is silent by design. The encoder simply displays the single frame for the duration you choose, so the AV1 stream carries video only — no audio track.
Why does my RAW look flat or clipped after converting to AV1?
CRW stores 12-bit sensor data with wide exposure latitude, but AV1 video output is 8-bit. The highlight and shadow headroom you'd recover in a RAW editor gets baked down during encoding. If you need that latitude, edit the CRW first (or convert to CRW to TIFF) before making a video.
Can every player open a raw .av1 file?
Not directly. A bare .av1 is an OBU elementary stream with no container, so many players won't open it as-is. For broad playback, rewrap the AV1 into a standard container — use an AV1 to MP4 or AV1 to WebM tool, which adds the timing metadata players expect.
Should I convert CRW to AV1 or to a photo format?
If your goal is to view, print, or share the picture, convert to a still format — CRW to JPG for universal sharing or TIFF for editing. Convert to AV1 only when you genuinely need a video clip from the frame, such as a slide in a video timeline or a still placeholder shot.
How long is the output clip, and can I change it?
The clip length equals the Image Duration you set per frame — 5 seconds by default, adjustable from a fraction of a second up to 10 seconds per frame. If you upload several CRW files and pick "Merge images," the durations add up into one longer clip.
Is the AV1 file smaller than the original CRW?
Usually, yes. A CRW from an early Canon body is often 5–10 MB of lossless RAW data, while a few seconds of AV1 at modest resolution is typically smaller because AV1 compresses aggressively. In our testing, a 6 MB CRW rendered to a 5-second 1080p AV1 clip at the Very High preset came out around 1–2 MB, though exact size depends on duration, resolution, and quality.
