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
Strip the image of any profiles, EXIF, and comments to reduce size

Bitmap (BMP) is a pixel-based file format that stores two-dimensional images, generally without any compression. BMP utilizes a dot matrix data structure called raster graphics, which establishes the color depth of the image. BMP is mostly used for digital publishing of photographs. However, due to the lack of compression, BMP files are usually large.

How to open a BMP file?

BMP can be device-dependent or independent. BMP opens readily in the Microsoft Paint application and is often associated with Microsoft operating systems. Despite the association with Microsoft, a device-independent BMP, or DIB, can open on almost any device, operating system, or application. 


In addition to opening BMP files, many applications can be used to create them, such as Adobe Illustrator. Should you need to convert the BMP into a vector-based image, then consider using CorelDRAW. Other applications that can open BMP files include Adobe Photoshop, Microsoft Photos, Apple Preview, Apple Photos, and ColorStrokes.

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.
