It's a common pattern: you find a free PDF tool, do the work of uploading your file, and only then discover you need to create an account — or wait through a countdown timer — before you're allowed to download the result.
Requiring an account lets a service collect emails for marketing, track usage per user, and gate more features behind a paid tier later. None of that is inherently wrong for a business model, but it does add friction to a task that's otherwise quick.
Because pdfvelo's tools run the actual processing in your browser rather than on a server, there's no account system behind them to begin with — there's nothing to log into, because there's no server-side job tied to a user record. You open a tool, do the task, and download the result.
