ตัวแปลงไฟล์ออนไลน์ฟรี OTB เป็น PGX

This format was created by Nokia for use in its proprietary phones. A bitmap image was used to transfer image files between devices over a wireless connection. It was mainly used when exchanging multimedia text messages that support inserting pictures.

This is an image file format that is stored without the use of compression algorithms. It is used in the JPEG 2000 standard. This format is capable of storing only one single component, so it is limited to displaying grayscale tones. If you combine multiple PGX files, then you can make a color image.
