ARW to WEBP Converter

Convert ARW files to WEBP. Batch, free and without uploading.

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

WEBP is Google’s format for the web. It stores the same image about 25–35% smaller than JPG and supports transparency and animation. WEBP 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 ARW 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 WEBP files one by one or as a ZIP.

Frequently asked questions

Will converting to WEBP reduce quality?

WEBP 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 ARW files are converted to WEBP inside your browser and never sent to a server.
