Which file task wastes the most time in your workflow?

I’m Dawson, the maker of Any File Type. I built it around the small file jobs that interrupt bigger work: an image that is too large to upload, a PDF that needs a few pages removed, a format that will not open, or a folder full of files that need the same change.

The toolkit brings conversion, photo editing, PDF tools, and developer utilities into one browser workspace. Free tools are available, with optional Pro features; supported workflows process files locally.

What is the one file task you keep repeating, and what would make it easier? Specific examples or confusing steps are especially helpful. You can try the tools at https://anyfiletype.com.
