Uploading from mobile devices should be entirely possible. Unless you have an image editing/conversion application installed, I would be cautious about changing the file type; it is not as simple as changing the name. What is the name of the image you are trying to upload? If it is a generic name such as IMG_20171225143726.png, the upload may be blocked by a page name blacklist on the wiki your are trying to upload to.
