The core method

Open Merge PDF, upload every file that belongs in the bundle, arrange them into reading order, merge, download. Guests can do it free within fair daily limits — no installs, no signup to start.

Ordering doctrine

The reader's journey decides: cover documents first, main content next, supporting annexures last — or whatever the portal's checklist dictates. Order set before merging saves re-merging after.

After the merge

Big bundle? Compress it to the upload limit. Needs pagination? Add page numbers so the sequence runs 1–N. Wrong order discovered late? Organize PDF reorders without re-merging. Files are processed temporarily and deleted automatically — there is no general cloud storage.
