How to Download and Attach Files that Aren’t Images or Documents in iPhone

Due to the limited nature of iOS, downloading and attaching files—especially anything that isn’t a document or image—can be a challenge. It takes a bit of work if you plan on attaching an executable, zip, or some other sort of file.

The easiest workaround here is to save the file directly to Gmail.

When you download the file, Safari defaults to an “Open in…” box. Tap the “More” button here, and then choose the “Gmail” option.

 

Note: If Gmail isn’t an option here, scroll to the end of the first line and choose the “More” option. Slide the toggle next to Gmail to add it to your share sheet.

 

When you save a file to Gmail via the share sheet, Gmail automatically creates a new message with the file already attached and ready to send.
