A J2K file is an image that is compressed using the wavelet compression instead of DCT compression.
The XLTM file extension represents files that are generated by Microsoft Excel as Macro-enabled template files. XLTM files are similar to XLTX in structure other than that the later doesn't support creating template files with macros. Such template files are used to generate and set the layout, formatting, and other settings along with the macros to facilitate creating similar XLSX files then.
يمكنك أيضا تحويل J2K إلى العديد من تنسيقات الملفات الأخرى. يرجى الاطلاع على القائمة الكاملة أدناه.
