Lumen vs iLovePDF
iLovePDF is one of the best-known online PDF tools. Lumen is newer and takes a different approach — private-by-default processing and one flat Pro plan instead of feature-gating everything. Here's how they stack up.

The bottom line
If you value privacy (files never leave your device) and want AI + form autofill baked in, Lumen wins. If brand familiarity and mobile apps matter more, iLovePDF is a solid choice. Both are honest about what's free.
