Honest overview
Smallpdf is one of the earliest web PDF mergers, but its free tier is heavily restricted: non-paying users are limited to just two tasks every 24 hours before encountering a hard paywall screen. PdfPixels Merge PDF delivers a clean, modern drag-and-drop assembly workspace that lets you combine unlimited PDF files, reorganize mixed page orientations, and export combined documents instantaneously without artificial daily limits or subscription nag-screens.
