Merge PDF Files & Combine into One
Combine multiple PDFs into one — remove, rotate and drag pages across files in a page-level workbench, undo/redo any edit. Free, no sign-in, nothing uploaded under 10 MB.
Processing and data safety
Section titled “Processing and data safety”Small files merge entirely in your browser and are never uploaded (no hard size cap); combined files over roughly 10 MB are better handled by optional Pro cloud merging (sign-in required; uploads are auto-deleted after the retention window and can be deleted early).
Input and output
Section titled “Input and output”- Formats: PDF
- Flow: Multiple PDFs → one merged PDF
How to use
Section titled “How to use”- Add two or more PDFs — every page lands in the page workbench (thumbnails render for the first 30 pages per file; later pages still merge as-is).
- Rotate (↺/↻) or remove (✕) individual pages, drag cards to reorder across files, and undo/redo any edit; the file list still supports whole-file add/remove and sort-by-name.
- (Optional) tick “Generate a table-of-contents page” — only files with kept pages get entries; it paginates automatically for many files.
Key details and limits
Section titled “Key details and limits”- Source bookmarks are preserved as a flat list pointing at their page’s merged position; bookmarks of removed pages are dropped. Complex form fields may not carry over perfectly.
- Thumbnails render for the first 30 pages per file (kept consistent with Split PDF) — later pages still merge as-is; use PDF Page Organizer for per-page work on very large files.
- No hard local size limit; files over the inline threshold (~10 MB) are better handled by the cloud option.
