Start with the job, not the brand. A merge, an edit and a redaction are different operations.

Merging versus organizing

For two complete documents, a merger is enough. If you need to interleave pages, choose a visual page organizer. For splitting into sections, choose a splitter.

Sensitive files

These linked PDF24 utilities process files on the provider's servers. For tax records, confidential contracts or medical documents, use an approved local application instead. Never treat flattening or drawing a black rectangle as secure redaction.
