DNG to AVIF Converter

Convert DNG files to AVIF. Batch, free and without uploading.

This tool converts DNG files to AVIF. DNG is the RAW format of Adobe DNG cameras. It keeps unprocessed sensor data; conversion uses the camera’s white balance and colour settings.

AVIF is a next-generation image format based on AV1 video coding. It usually beats even WEBP on size, but older programs may not open it. AVIF is lossy, and you choose the quality with the slider. For photos, 80–90% makes the file much smaller with a loss you won’t notice. RAW files are large, so each photo may take a few seconds.

Conversion happens inside your browser; your files are never sent to a server.

How to use

1. Drag and drop your DNG files, paste them from the clipboard, fetch one from a link, or use "Choose files".
2. Set the quality and, if you like, a maximum size.
3. Press "Convert" and download the AVIF files one by one or as a ZIP.

Frequently asked questions

Will converting to AVIF reduce quality?

AVIF is lossy, but at 85–90% quality the difference isn’t visible. Lower quality means a smaller file.

How many files can I convert at once?

There is no limit. Select hundreds of files together and download the results as one ZIP.

Are my files uploaded anywhere?

No. Your DNG files are converted to AVIF inside your browser and never sent to a server.
