About the RAW Image Converter
Looking for a fast, free way to use a raw to jpg converter without installing software? RAW Image Converter by Onnax Tools runs entirely in your web browser, which means your files are processed on your own device — never uploaded to a server.
Convert camera RAW previews (CR2, NEF, ARW, DNG) to JPG or PNG. The tool works on Windows, macOS, Linux, Android and iOS — anything that runs a modern browser — and it is completely free for personal and commercial use.
Key Features
100% private processing
Files are processed with JavaScript inside your browser. Nothing is uploaded, so nothing can be intercepted, stored or leaked.
Accurate conversion
The converter preserves your content faithfully and tells you clearly when a format limitation applies, instead of silently degrading files.
Completely free, no limits
No trial periods, no watermarks, no daily quotas and no account requirement — every feature is free for personal and commercial use.
Works on any device
Runs in Chrome, Firefox, Edge and Safari on Windows, macOS, Linux, Android and iOS. If it has a modern browser, it works.
Instant results
Because there is no upload or download queue, processing starts the moment you add a file and usually finishes in seconds.
No software suite required
Get results normally locked behind Microsoft Office, Adobe or specialty software — for free, in a tab.
How to Use the RAW Image Converter — Step by Step
Add your file
Click the upload area or drag and drop your file directly onto it. On phones you can pick from your gallery or camera.
Choose your settings
Adjust the options that appear — quality, size, format or layout depending on the tool. Sensible defaults are pre-selected, so you can also skip straight ahead.
Run the tool
Press the action button and watch the progress bar. Everything happens locally, so speed depends only on your device — not on a server queue.
Download the result
Preview the output where available, then click download. Multiple output files are automatically bundled into a convenient ZIP archive.
Why Use an Online RAW Image Tool?
It helps to know what each format is actually good at. Camera RAW files (CR2, NEF, ARW, DNG) hold unprocessed sensor data. They give photographers maximum editing latitude but cannot be opened by most everyday software.
Browsers can natively decode more formats than most people expect, and open-source JavaScript libraries fill the remaining gaps. This converter combines both so files are transformed locally — faster than any upload-based service and inherently private.
Choosing the right tool usually means trading off cost, convenience and privacy. Desktop suites are powerful but expensive and heavy; upload-based sites are convenient but ask you to trust them with your files. Local in-browser processing is the third way — the convenience of a website with the privacy of offline software, at no cost.
