What is an MRW file?

MRW – Minolta RAW photo. MRW is a RAW photo format from Minolta: the data straight from the camera's sensor, before it is turned into a JPG. It keeps more detail to adjust, but needs a RAW converter to be opened.

What is an ICO file?

ICO – Windows icon. ICO is the Windows icon format. One file holds the same picture in several sizes, each at most 256 × 256 pixels; browsers also use it for the small icon on a tab (the favicon).

Good to know

  • Icons are small: the picture is shrunk to fit 32 × 32 pixels unless you choose another size in Options (up to 256 × 256).
  • MRW files are developed on our server with the camera's own white balance, then saved as ICO. Expect a good-looking picture, not a replacement for your RAW editor.
  • Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.

Frequently asked questions

Is converting MRW to ICO free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my MRW pictures uploaded anywhere?

This conversion runs on our server, because a browser can't develop camera RAW files. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion.

How large can the MRW file be?

Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.

Can I change the size or quality of the ICO?

Yes. Click Options next to the file to set a width and height, choose a quality, remove metadata and more. Only the settings that make sense for MRW to ICO are shown.

Can I convert several MRW files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
