WebP to RAW Converter
Convert WebP to RAW in your browser. You download a Linear DNG (.dng), not a .raw: only a camera can create a genuine RAW, and every editor that opens RAW also opens DNG. Nothing is uploaded.

How to use WebP to RAW
- 1
Add your WebP files: drop them here, choose them, or paste from the clipboard.
- 2
Pick the colour that replaces transparent areas, since DNG has none.
- 3
Click Convert. Each file is decoded and encoded in a background thread on this device.
- 4
Download the .dng files one at a time or together as a ZIP.
Why use Aback Images for webp to raw
Where a RAW would go
RAW files are opened by Lightroom, Photoshop Camera Raw, Capture One, darktable, RawTherapee and dcraw-based tools, and every one of them opens the DNG too.
DNG next to WebP
The DNG is written uncompressed, so expect it to be several times larger than the WebP, which stores lossy VP8 coding or lossless VP8L.
No new artefacts
WebP is already lossy, since it stores lossy VP8 coding or lossless VP8L; the DNG keeps the decoded pixels uncompressed, so this step adds no compression damage of its own.
Processed on your device
Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.
WebP vs RAW
What changes from WebP to RAW
Encoding: the WebP uses lossy VP8 coding or lossless VP8L; RAW uses uncompressed, lossless JPEG or vendor-specific coding of the sensor data, depending on the maker, and the download is a Linear DNG: demosaiced 8-bit RGB with the colour matrices raw editors need.
Bit depth: 8 bits per channel in the WebP; RAW allows 12 to 16 bits per channel, and the DNG written here has 8 bits per channel, linearised.
Colour: RGB; lossy WebP stores colour at half resolution (4:2:0) in the WebP; RAW supports camera-native RGB from a colour filter mosaic, written here as 8-bit sRGB.
Transparency: the WebP stores it as a separate alpha plane, available in lossy as well as lossless files; the DNG has none, so transparent areas are filled with the colour you choose.
Animation: ANMF frame chunks, each with its own delay and blending; the DNG holds one image, so only the first frame is converted.
Metadata: the WebP can carry EXIF, XMP and ICC chunks; RAW can carry EXIF and vendor maker notes, almost always with an embedded JPEG preview, but nothing is copied across.
About WebP
WebP is Google's web image format. It supports lossy and lossless compression, transparency and animation, and is typically 25 to 35 percent smaller than JPEG at the same visual quality.
A WebP is a RIFF file: 'RIFF', a length, 'WEBP', then chunks. A simple lossy file is one VP8 chunk and a lossless one is VP8L; the extended VP8X header announces alpha, animation, ICC, EXIF or XMP chunks.
WebP files usually come from websites, Chrome's Save image as, CDNs and Android apps.
About RAW
Camera RAW files (CR2, CR3, NEF, ARW, DNG, ORF, RW2, RAF and others) hold the unprocessed sensor data from a camera along with an embedded full-size JPEG preview rendered by the camera.
.RAW is an extension rather than one format. Panasonic and Leica compacts wrote TIFF-like .RAW files before Panasonic moved to RW2, and scanners and scientific cameras use .raw for headerless dumps with no width, height or layout recorded, which nothing can read without being told those values.
RAW files come from older Panasonic and Leica compacts that saved .RAW, and scanners or scientific cameras that use the extension for pixel dumps.
When converting WebP to RAW makes sense
Forms and workflows that ask for RAW usually feed a raw editor, and each of those opens DNG as well, so the DNG can take the RAW's place. Keep the WebP if you only need to view or share the picture.
What RAW offers when it comes straight from the camera: Maximum editing latitude in RAW editors; Includes a camera-rendered preview. Its drawbacks: Huge files; Every brand uses its own format; Phones, browsers and websites cannot display it.
Limitations
- WebP images saved from websites are often already resized and compressed for the page, so the result cannot be sharper than that copy.
- The DNG holds the decoded 8-bit pixels, so it adds no dynamic range or detail beyond the WebP.

Frequently asked questions
Why do I get a .dng file instead of a .raw?
A real RAW is written by a camera and holds the sensor's own readings (12 to 16 bits per channel, stored as uncompressed, lossless JPEG or vendor-specific coding of the sensor data, depending on the maker) along with EXIF and vendor maker notes, almost always with an embedded JPEG preview. A WebP holds no sensor data, so no software outside the camera can create a genuine RAW. The Linear DNG you get instead is Adobe's open raw format, and every editor that opens RAW files opens it with the same raw controls. It holds decoded pixels, so it adds no quality or dynamic range.
Does converting WebP to RAW lose quality?
DNG is written uncompressed, so the pixels are stored exactly as decoded. Artefacts already in the WebP stay, but nothing new is lost.
What happens to transparency when converting WebP to RAW?
WebP stores transparency as a separate alpha plane, available in lossy as well as lossless files. DNG has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
Will my animated WebP stay animated?
No. DNG holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
