If you haven’t heard of an RW2 file, you are not alone. It means nothing to most of us. And the people who know what it is, might not know what to do with them.
What Is a File Extension?
File extensions exist with every digital file we create. They not only tell us (and computers) what kind of files they are, but what programs can use them.
Digital images come with file extensions. No doubt you’ve heard of JPEG, but there are TIFFs, PNGs, and GIFs too. The ones you might not have heard of are the Raw versions.
JPEGs are a lossy file extension, meaning the quality reduces every time you open and save one. Raw file types retain much more data from every scene and can be over 5x larger, depending on the scene you are shooting.
Raw is a better way to go. That is if you plan on editing your images and know how to convert them. Luckily, we have all the information you need on the RW2 file.
What Does RW2 Mean?
An RW2 file is a Raw format image used by Panasonic. When you set and capture an image using the Panasonic Raw image setting, it gets the RW2 file extension. This extension needs converting if you plan on doing image editing from it.
Like other Raw files, there might be some problem with previewing the images on a computer. You need specialized software to read an RW2 file and to convert them. Specific programs, such as editing programs, and others from camera manufacturers, can help open an RW2 file.
The RW2 file is similar to other Raw formats, modeled after the TIFF (Tagged Image File Format). This format is for high-quality images. Unlike JPEGs, TIFFs are not lossy formats, so it doesn’t lose its quality with use.
How Do I Convert an RW2 File to JPEG?
To convert an RW2 file to a JPEG is an easy enough process with the right tools. The most important thing you need is software that can read an RW2 file. Adobe Lightroom is the most straightforward option, as it opens the RW2 file with no problem or prompt.
Adobe Photoshop is another program you can use. But it can be a little more complicated to use. As the RW2 file is a Raw image, Photoshop will force open Camera Raw (a Raw file convertor). This process is something you need to go through before you can open the image.
Lightroom has Camera Raw as part of its import process. Both of these programs allow you to import, edit, and then save or export the files as JPEGs. Then can be saved as TIFFs, PNGs or even GIFs.
Other than photographic editing software packages, ILoveImg.com is an online RW2 file converter. It is free and works on all operating systems.
How to Open an RW2 File?
Opening an RW2 file requires an editing software program such as Photoshop, Photoshop Elements, GIMP and RawThrapee, among others. Photoshop is a little more involved than others, as you need to go through the Camera Raw platform before being able to edit the image completely.
In Camera Raw, you need to press Open Image to use it in Adobe Photoshop. From there, you are free to edit your image. Lightroom is a better option as it opens Raw images without giving you notice.
LUMIX has a codec for the RW2 file, although this only works with Windows 7 and Vista. There are other tools, but some come with a financial burden. Your best bet is to convert them to easier-to-manage formats.
NB: There is a chance that you can’t open your images due to your computer misreading the format. Microsoft Outlook uses a similar file extension (RWZ) and could be mixing the formats up. There is also RW3, which belongs to RapidWeaver 3.
It is best to convert your images to a DNG (Digital Negative) that has more options for usage.

Is an RW2 File Better Than JPEG?
Typically speaking, any Raw image file is better than a JPEG. But, only if it is something you need. It depends, like always, on what you plan to do with your images.
A JPEG is a lossy file format, meaning it’s losing quality every time you open it. A Raw format RW2 file gives you much more data, and therefore, retains high quality.
