Lower values yield better compression but lower image quality. Default (92) is a good balance between image quality and compression. Please set a value between 1 - 100
Lower values compress the image faster at the expense of lower compression quality and bigger file size.
Correctly orient the image using the gravity sensor data stored in EXIF

Sony Alpha Raw (ARW) is the proprietary RAW file format for Sony digital cameras. It is also known as Sony Digital Camera RAW file. ARW is an uncompressed, unprocessed image file, which contains all of the file’s information, as captured by the sensor in the camera that captured the image. Since the file is not compressed, no data is lost, which is the main benefit of ARW and all RAW file types.

How to open an ARW file?

Sony provides the Sony® RAW Driver as the default program for opening an ARW file. It will allow you to view an ARW file on a Microsoft Windows operating system (OS) as you would a JPEG. Adobe Photoshop is another program that is commonly used to open ARW.


On Linux/Unix, use the open-source program darktable to view ARW. Across platforms, use XnView MP. ARW is often converted to JPEG (ARW to JPG) after post-processing edits.

WebP is an open-source file type that uses predictive compression to create images that are ideal for web pages and mobile applications. WebP images are as much as 30 percent smaller than JPEG (JPG) and Portable Network Graphics (PNG) files, with similar visual quality. WebP images load quickly on web pages and mobile applications.

How to open a WebP file?

The default program for opening WebP is Google Chrome (Chrome), which works across platforms. WebP files also open automatically on GIMP and Microsoft Paint. Besides Chrome, all other web browsers support the WebP format.

Alternative free viewers to try are Pixelmator and Photopea. Also, try Corel PaintShop Pro. Prior to using IrfanView, Windows Photo Viewer, and Adobe Photoshop, be sure to install the plugins for opening WebP.
