| Requirement | Value |
|---|---|
| Input | Two or more PDFs |
| Order | You set it |
| Size limit | Optional |
Files are joined from top to bottom in the order shown, and the arrows on each card move them up or down.
If the portal caps the combined file, set a size limit. Reaching it flattens the pages into images, so the text can no longer be selected or searched — worth knowing before you choose it.
Everything happens inside your browser. The PDFs are never sent anywhere, which matters when they hold identity documents.
