iLovePDF is a well-known name for online PDF tools, and it's a reasonable option for a lot of tasks. If you're looking at alternatives, the main things worth comparing are how files are processed and what the free tier actually includes.
pdfvelo runs every operation — merge, split, compress, rotate, image to PDF, and Word to PDF — entirely in your browser, with no account and no watermark. The trade-off is that very large files are limited by your device's own memory rather than a server's processing power, which in practice is rarely an issue for typical documents.
