StarlineConvert
Conversion here happens in the browser, which is not a compromise: the file is never uploaded, so there is nothing to intercept, store or delete, and a 40MB image costs the server nothing.

What it does
Image conversion
Image resizing
Data format conversion
What works today
Image format conversion between PNG, JPEG and WebP with a quality control; image resizing that scales to fit a width and never enlarges past the original; and CSV to JSON and back with a real CSV parser that survives quoted fields, embedded commas and escaped quotes.
What cannot run on this hosting
PDF conversion needs Ghostscript or qpdf. Video and audio need ffmpeg. Word, Excel and PowerPoint need a LibreOffice process. None exists on shared hosting, and none has a browser equivalent that handles real files correctly. They are listed as unavailable rather than shipped as buttons that fail.
What it would take
The same answer for all three: a worker process on a VPS with those binaries installed, fed by a job queue, with the browser polling for the result. That is a hosting decision rather than a backlog item, which is why it is written down here instead of promised.
