Good times to use it
Use Merge PDF for combining contracts, forms, receipts, scanned pages, and supporting documents into one shareable PDF. It works well when you want one combined PDF containing the selected documents and page ranges and do not need a bigger workflow around it.
- Best fit: combining contracts, forms, receipts, scanned pages, and supporting documents into one shareable PDF.
- You start with two or more PDF files plus the desired order.
- The useful choices are file order, page range selection, whether to remove extra pages, and final filename.
- Check page sequence, duplicate pages, missing signatures, and whether cover pages appear in the right place.
- You end up with one combined PDF containing the selected documents and page ranges.
Use Merge PDF like this
- Start with two or more PDF files plus the desired order.
- Choose file order, page range selection, whether to remove extra pages, and final filename.
- Run the tool once, 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.
- Open the finished file once before you send or archive it.
What usually goes wrong
- 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.
- 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.
What the page is doing
- 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.
How your data is handled
PDF files are merged in your browser. Toolumina does not upload, store, read, or transmit the selected PDF content.
FAQ
Can I reorder PDFs before merging?
Yes. Use the ordering controls to move files up or down before creating the merged PDF.
Can I merge only certain pages?
Yes. Enter ranges such as 1-3,5 for each PDF, or leave the field blank to include all pages.
Are my PDFs uploaded?
No. Merging happens locally in the browser.
