Questions
There is no single answer, which is why this page lists 13 of them with their limits stated. If you want to avoid signing up entirely, 2 of these work with no account at all.
1 of the 13 sites here process your file inside the browser and never upload it — they are marked "On device". The rest send your input to their server, which is fine for public material and worth thinking twice about for anything personal.
Some already have. 1 entry in this category has been retired and moved to the Archive with a working successor, so an old bookmark still leads somewhere useful.
