What a DNG file is
DNG, short for Digital Negative, is an open RAW format created by Adobe. Some cameras save DNG directly, several phones offer it as their RAW option in the camera app, drone pilots often find DNG files on their cards, and photographers sometimes convert other RAW files to DNG for archiving in Lightroom.
Because it's a RAW format, a DNG isn't a finished image. Many websites, upload forms, messaging apps and photo viewers can't open it, or show it with odd colors. When you need to share the photo, JPG is the safe choice.
How the conversion works
A DNG file usually contains a JPEG preview alongside the RAW data. ConvertirDocs extracts that preview and saves it as a JPG, so you get a viewable image in seconds without installing an editor.
The RAW data itself is not developed. You can't adjust exposure, highlights or white balance here, and you don't benefit from the extra detail a RAW editor could pull out. The size of the JPG depends on the preview stored in the file: some DNG files carry a full-size preview, others a smaller one, depending on the camera, phone or program that created them.
When it's useful
You shot RAW on your phone for a trip and now want to send a few pictures in a chat. A drone flight gave you DNG files and the client asked for quick JPG previews. You're looking through an old Lightroom archive on a computer that doesn't have Lightroom. Or a website asks for a JPG and all you have is the DNG. In all these cases a quick conversion gets the job done.
Your DNG files are not modified. If you later want a careful edit, the RAW data is still there for your editor.
In your browser, for free
ConvertirDocs reads the DNG files on your device, so nothing is uploaded and you don't have to wait for large RAW files to travel over the internet. There's no account, no watermark and no limit on the number of files. Select a whole folder and download the JPG copies in one ZIP.
After converting
The JPG files can go straight into other tools without selecting them again. Use “Compress image” to fit a size limit in KB for email or an upload form, “Resize image” to set exact pixel dimensions for a website, or “Crop image” to get a square or vertical frame for social media.
If a DNG from your phone gives you a small preview, check whether the phone also saved a regular JPG or HEIC copy of the same shot. Many camera apps keep both, and the regular copy is often full size.
