How to use Merge PDF
- Prepare two or more PDF files plus the desired order.
- Set file order, page range selection, whether to remove extra pages, and final filename before running the tool.
- Generate or process the result, then review page sequence, duplicate pages, missing signatures, and whether cover pages appear in the right place.
- Copy, export, or download one combined PDF containing the selected documents and page ranges.
- Run a second pass if the destination system, document, or workflow has stricter requirements.
What to know before you use it
- Each selected PDF is loaded in the browser with pdf-lib.
- Optional page ranges are parsed locally, then copied into a new PDF document.
- The merged PDF is saved as a local download without server-side processing.
- PDF merging preserves pages as PDF pages rather than rasterizing them, which usually keeps text selectable when the source allows it.
- Encrypted, malformed, or permission-restricted PDFs may fail before merging because the browser library cannot safely read them.
Checks and edge cases
- Put the main document first, then append receipts, screenshots, certificates, or signed pages in review order.
- Use Split PDF before merging if a source file contains pages that should not be included.
How your data is handled
PDF files are merged in your browser. Toolumina does not upload, store, read, or transmit the selected PDF content.
