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.

Comic Book Zip (CBZ) is a file extension for digital comic book files that are compressed and archived into the ZIP file format. You can unzip CBZ using a ZIP utility as you would any other ZIP file. CBZ is a useful file type for creating Comic eBooks. The letters “CB” in the name lets readers know it contains comic book files, while the “Z” denotes that it was archived via ZIP. 

How to open a CBZ file?

CBZ opens by default in the CDisplay Comic Reader, which is freeware. CDisplayEx is another great program to use. On mobile, try Comic Rack (Android) and iComix (iOS). On Linux/Unix, try MComix.  


Since CBZ is an archive file format, converting it involves extracting the files and then re archiving them into another archive file format. Alternatively, after extracting the files, you can convert them individually to other file types, such as CBZ to JPG or CPZ to PDF

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.
