StuHub PDF Merge vs iLovePDF — how the two compare
iLovePDF is the highest-traffic online PDF toolbox in the world. Its merge tool is everywhere students and admins share links. StuHub's merge is comparable in pure combining accuracy — same pdf-lib engine other in-browser merges use — but it never touches a server. The full iLovePDF ecosystem is deeper (signatures, conversions, desktop apps), so this comparison is about the merge tool alone.
Feature-by-feature
Frequently asked
Will the merged output look identical?
Page content, fonts, and layout: yes, byte-accurate. Document-level bookmarks and interactive form fields: no — those are dropped by both the in-browser pdf-lib engine and the iLovePDF free plan.
Which is faster?
For files under 100 MB, StuHub is usually faster because there is no upload step. iLovePDF wins on very large files because its servers have more RAM than a typical laptop.
Can I re-order pages after merging?
Both tools let you re-order source files before merging. For page-level reordering inside a single PDF, use a dedicated reorder tool (coming to StuHub later).
