RAW to WEBP Converter
FileFlip converts RAW to WEBP entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a RAW file to WEBP?#
- Drop your RAW file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to WEBP and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the WEBP file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting RAW to WEBP lose quality?#
Yes, once. RAW keeps everything and WEBP does not, so this is the first time the file meets a lossy encoder. At high quality the difference is hard to see, and it is worth keeping the RAW original, because every later re-save of the WEBP loses a little more.
Is it safe to convert RAW files online?#
Yes, because nothing is uploaded. FileFlip converts RAW files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What RAW to WEBP actually does to the file#
Converting RAW to WEBP runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, encodes a lossless source with a lossy encoder for the first time.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: RAW → WEBP |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossy, first generation |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
Worth knowing before you start:
- camera raw is demosaiced with ImageMagick's defaults, which will not match the camera's own rendering
- some cameras write lossily compressed raw, so the source is not always a complete sensor record
What is a RAW file?#
A .raw file is a generic label for unprocessed camera sensor data or a headerless array of pixel values, and the extension alone does not identify which of several unrelated internal formats a given file actually uses, including early Panasonic digital cameras' TIFF-based sensor dumps and the Kyocera Contax N Digital's own raw format.
A .raw extension shows up because a specific camera or tool produced it, such as an early Panasonic digital camera or the Kyocera Contax N Digital, not because someone chose it over a named raw format.
Convert a .raw file to a mainstream format such as TIFF or DNG once its source is known and it has been processed, since the ambiguous extension keeps it unreadable by most software without extra information.
What is a WEBP file?#
A WebP file holds a still or animated image compressed with Google's WebP codec, built as a single format to undercut JPEG, PNG, and GIF on file size at comparable quality.
Use WebP for images on the web: it's the general-purpose replacement for JPEG, PNG, and GIF now that every major browser renders it natively.
Convert WebP to JPEG or PNG when the file needs to open in older software, a print workflow, or an app that still doesn't recognize the .webp extension.
RAW to WEBP questions people ask#
Is a RAW file the same as CR2, NEF, or ARW?
No. CR2, NEF and ARW are each one manufacturer's own raw format tied to that manufacturer's cameras, while a bare .raw extension has been reused by several unrelated sources, including early Panasonic cameras and the Kyocera Contax N Digital, so it does not identify a single format the way those extensions do.
What software opens a RAW file?
It depends entirely on what produced it. A .raw file from a camera with a known raw format opens in that camera's raw-capable software, while a headerless raw pixel dump needs a tool such as Photoshop's raw importer or GIMP's raw image data loader, which asks for the exact dimensions and bit depth before it can display anything.
Why won't a normal photo viewer open my RAW file?
A .raw file usually holds unprocessed sensor or pixel data rather than a standard encoded image, and without embedded metadata identifying its dimensions, bit depth and color layout, a generic image viewer has nothing to go on and fails to render it.
What is a WebP file?
A WebP file is an image saved with Google's WebP codec, which can encode a picture either losslessly or lossily and supports both transparency and animation in the same format. Google introduced it in 2010 to replace JPEG, PNG, and GIF with one format that produces smaller files at comparable quality.
