Convert ARW to WebM Online

This converter renders a Sony ARW raw photo into a finished frame and holds it on screen as a single still image for a duration you choose, then packages it as a WebM video clip. There is no motion and no audio — just your photo shown as a steady image for as long as you set. It is the quick way to turn a RAW shot into a placeholder slate, a title card, or a still you can drop straight onto a web-video timeline without re-encoding from another format. If you only want a picture to view or share, convert to ARW to JPG instead and keep the original ARW as your master.

How to Convert ARW to WebM

  1. Upload Your ARW File: Drag and drop your Sony .arw file onto the page or click "+ Add Files" to browse from your computer. You can queue several photos at once.
  2. Set the Image Duration: Open Advanced Options and pick how long the still shows under "Duration" — anything from a fraction of a second (such as 1/24s, 1/30s, or 1/60s, which match common frame rates) up to 10 seconds per frame, with 5 seconds as the default.
  3. Pick Quality, Codec, and Background: Choose a Quality Preset ("Very High (Recommended)" keeps detail), leave the Video Codec on VP9 or switch to VP8 for legacy playback, and set a Background Color (black by default) to fill any letterbox bars when the photo's aspect ratio doesn't match the output.
  4. Convert and Download: Click "Convert" and download your WebM. No sign-up, no watermark.

Frequently Asked Questions

Does the WebM clip have any motion or sound?

No. The conversion takes one ARW photo and displays it as a static image for the duration you set. There is no panning, zooming, or animation, and the output carries no audio track — it is a silent, single-frame still rendered into a WebM video, not a slideshow. If you have several photos and want them to play in sequence, use "Merge images" to combine them into one clip; otherwise each file becomes its own one-frame video.

Does rendering an ARW to WebM lose my raw editing latitude?

Yes. An ARW is an unprocessed negative — white balance, exposure, and highlight recovery are all still adjustable while it stays raw. Converting to WebM first renders the raw, baking in the camera's current interpretation as flat finished pixels, so you can no longer rebalance color or pull back blown highlights afterward. Always keep the original ARW as your master and treat the WebM as a disposable export.

Which WebM codec does the output use — VP8 or VP9?

VP9 by default. WebM is an open container that carries VP8 or VP9 video, and you can switch the Video Codec under Advanced Options. VP9 generally gives smaller files at the same quality, while VP8 has the broadest legacy playback support. Both are royalty-free and, per caniuse, play natively in Chrome 25+, Firefox 28+, Edge 79+, Safari 16+, and Opera 16+.

Why does my photo have black bars in the video?

An ARW frame's aspect ratio may not match your chosen output resolution. Rather than stretch or crop your photo, the converter fills the leftover space with the Background Color you select — black by default. Pick white or another color under Advanced Options if black bars don't suit the project.

Should I convert ARW straight to WebM, or extract a photo first?

If you just want a usable still to view, edit, or share, convert to a photo format with ARW to JPG instead. Go to WebM only when you specifically need a video clip — a slate, a title card, or a still to place on a web-video timeline. For a universal video file that plays on more devices and editors, use ARW to MP4. In our testing, a 5-second WebM from a single 24-megapixel ARW at the "Very High" preset came out only a few hundred kilobytes, because a motionless frame compresses heavily under VP9. Your file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after conversion — no sign-up, no watermark, never shared or made public.
