My app is not visible for JPEG,TIFF and Text documents in Share options menu in Safari.

My app is declared with Document Types doc, xls, ppt, png, jpeg, tiff, txt, pdf. After opening JPEG/TIFF/TXT image in safari (by downloading), and Tapping on Share button, My app is not visible in Share menu and even not able to find in More options also. If I do the same process with Docx,PDF I am able to see My app in Share options. My app is not implemented any Share extension. If I do the same process in Adobe Acrobat/ Mail app, My app is visible for all declared document types. For safari only, my app is not visible for some documents in Share options menu.
