.wbmp refers to the wireless application protocol bitmap monochrome graphics file format. The format was initially developed by the WAP forum which later become part of the open mobile alliance. WBMP files are optimized for mobile devices prior to the advent of smartphones and is categorized as a raster image file format. Mobile network services such as SMS and MMS on GSM carriers typically have compatible support for this format, allowing users to send graphics saved in this format.
PNG stands for portable network graphics. It is the raster graphics format associated with the .png filename extension. Unlike GIF format, the limitation of 256 colors does not hold with the PNG format. In fact this among other reasons was the motivation behind development of the PNG format to improve upon the GIF format. The PNG format however uses a single image format and thus does not support animations. Because the format was engineered to ease the distribution of graphic files across computer networks it is also not well suited for professional graphics.
FreeFileConvert uses tuned encoding for WBMP to PNG conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload WBMP files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized PNG results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent PNG audio with dependable progress tracking.
The wbmp file format only supports a color palette of black and white which aids in keeping file sizes at the minimum possible. Binary integers are used to differentiate pixels of opposing colors. The file structure consists of several fields including the type field which represent the type of image, a fixed header of 1 byte in size, a width and height field to define the pixel resolution of the file, and finally the data field which holds the image data.
The PNG formation become a published ISO standard in 2004 as ISO/IEC 15948, although it was formally accepted for use by the internet engineering steering group in 1996. The PNG format has broad support for various color palettes including 24 bit RGB, 32 RGBA, and grayscale with optional support for transparency. The lossless data compression method used by PNG is DEFLATE.
