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 the .av1 file?
Not directly. The file is AV1 video in a Matroska wrapper, but most players key on the extension and don't expect .av1 — VLC and mpv open it as-is, and renaming it to .mkv (same bytes) satisfies extension-picky apps. For broad playback, convert it with an AV1 to MP4 or AV1 to WebM tool.
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.
Is CRW the same format as CR2 or CR3?
No. CRW is Canon's original raw format, built on the CIFF container and used by early bodies such as the EOS D30 through the 10D and the PowerShot G1–G5. Canon replaced it with the TIFF-based CR2 in 2004 and later CR3. All three are Canon raw stills, but CRW is the oldest and least widely supported, which is one practical reason to render it into a current format.
Do I need Canon's software to open the CRW before converting?
No. The converter decodes the CIFF raw data directly, so you can upload the .crw straight from a card or an old archive without installing Canon Digital Photo Professional or any other application first. Only your intended edits — if any — would call for a dedicated raw editor.
Why do the colors look different from what I saw in my raw editor?
A raw file has no single fixed appearance: a raw editor lets you choose white balance and tone, and it remembers those choices. To make a video, the converter must pick one interpretation and demosaic the sensor data into fixed RGB, so the clip reflects a default rendering rather than your editor's look. If a specific look matters, develop the CRW in a raw editor and export a still first, then build the clip from that.
