i have used your online tools to overlay one PDF on top of another with excellent results recently. However; I have tried the same process over the last few days but unfortunately I cannot select any PDF files to upload, as they are greyed out. I can select other files such as DOC or JPG, but not PDF. I am using an iPhone8 with the latest iOS.
Any help you can give would be appreciated.
When you click the file upload box and when the file selection dialog opens, what files can you select there? Is there a file extension filter in this dialog where all supported types are listed? Can you post the types here or can you send a screenshot or foto to email@example.com?
Hmm, I've tried it with my android and this works well. The PDF format is also in the list of accepted formats just like the other formats that you can use. All my other devices also works. But currently, I've no Iphone at hand so that I can test with such a device. Can you select PDF files in one of the other tools?
