RAW to JPG Converter
Turn camera RAW files into shareable JPG, PNG or WebP images. The RAW decoder runs entirely in your browser — your original files are never uploaded.
RAW decoding runs in your browser — your files are never uploaded.
How it works
This tool runs LibRaw, the same
open-source library many desktop photo apps use to read camera RAW, compiled to WebAssembly so it
executes inside your browser tab. When you click Convert, the decoder is fetched
once from a CDN and cached. Each RAW file is then handed to LibRaw locally — never uploaded — where
it is demosaiced into full-resolution pixels, drawn onto an HTML <canvas> and
exported as a JPG, PNG or WebP you can download. The heavy decoding happens in a background worker
thread, so the page stays responsive, and the buffers for each file are released before the next
one is processed.
How to convert a RAW file to JPG
- Drop a camera RAW file (CR2, NEF, ARW, DNG and more), or click to choose one or several.
- Pick an output format — JPG, PNG or WebP.
- Choose Full quality for a true demosaic, or Fast preview for the embedded JPEG.
- Click Convert and wait for the decoder to finish.
- Download each converted image.
Full quality versus fast preview
A RAW file holds the unprocessed sensor data plus a ready-made JPEG that the camera generated for its own screen. This tool can give you either. Full quality runs the complete demosaic, reconstructing colour from the raw photosites at full resolution — the right choice when you want the best image to edit or print. Fast preview simply pulls out the embedded JPEG, which is almost instant and ideal for quickly triaging a card full of shots or building a contact sheet, at the cost of resolution and the camera’s baked-in processing. Large RAW files are heavy in memory once decoded, so if you are converting a big batch, the preview mode is gentler on your device.
Why convert RAW in your browser
RAW files are big, original and often private — an unreleased shoot, a client’s photos, personal pictures straight off the card. The usual online converters make you upload every one of those large files to a server, wait in a queue, and trust a third party with your originals. Here the decoder runs in your own browser tab, so there is no upload, no waiting on someone else’s server and no watermark. The honest trade-off is the first-run download of the decoder (about 1.3 MB, cached afterwards) and the fact that a true demosaic of a 24–50 megapixel file does real work and uses real memory. Once you have a JPG, you can shrink it with the compressor, set exact dimensions with the resizer, or read any text in it with image to text.

Frequently asked questions
Are my RAW files uploaded to convert them?
No. The conversion runs entirely in your browser using LibRaw compiled to WebAssembly. Your RAW file is decoded on your own device and never sent to a server — which matters, because RAW files are large, original and often private. Only the decoder itself is downloaded once, then cached.
Which RAW formats are supported?
The built-in LibRaw decoder reads the common camera formats — Canon CR2 and CR3, Nikon NEF and NRW, Sony ARW, Adobe DNG, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, Leica RWL, Samsung SRW and many others. If your camera writes a standard RAW, it will almost certainly open here.
What is the difference between Full quality and Fast preview?
Full quality runs the complete demosaic, turning the raw sensor data into a true full-resolution image — slower but the best result. Fast preview instead extracts the JPEG that your camera already embedded in the RAW: it is near-instant and great for quick proofs or contact sheets, though it is usually smaller and processed by the camera rather than from the raw pixels.
Why is the first conversion slow, and why do big files take time?
The first time you convert, your browser downloads the WebAssembly decoder (about 1.3 MB), which is then cached for next time. Decoding itself is real work: a 24–50 megapixel RAW is hundreds of megabytes once expanded in memory, so a full demosaic on a large file naturally takes a few seconds and uses a lot of RAM.
Can I use the converted images commercially?
Yes. The tool is free and the LibRaw library it uses is released under the LGPL-2.1 and CDDL licences, both of which permit commercial use. The JPG, PNG or WebP files you export are your own photos — they are yours to use however you like.
Image Tools converts RAW files entirely within your browser. Your files are never uploaded. The first run downloads the open-source LibRaw decoder (about 1.3 MB), which is then cached for offline use.
