How to do it, step by step
- Tap the selection area and choose two or more PDFs (or drag them onto it).
- Reorder the list by dragging the items: the order in the list is the order of the pages in the final file.
- Remove with the × any file that got in by mistake.
- Click Run and download the single PDF.
When this is useful
Paperwork for a job application or a loan
Banks, rental companies and HR usually accept a single attachment. Combine ID, proof of income and proof of address in the order requested.
The month’s invoices for the accountant
Instead of ten emails or ten attachments, one PDF with all the invoices, in date order.
Chapters of a paper written in parts
Each member exports their section and you join everything before handing it in.
Tips for a good result
- Name the files 01, 02, 03 before selecting: it makes the order easy to check in the list.
- If the result gets too heavy for email, run it through Compress PDF afterwards.
- Check the order in the list before running; after downloading, reordering pages requires the Organize PDF tool.
What this tool does not do
- Password-protected PDFs must be opened and saved without the password before being merged.
- Very large files depend on your device’s memory, since nothing is processed on a server.
- Bookmarks (the outline) and form fields of each original file are not preserved in the merged file.
Frequently asked questions
- Can I combine PDFs and images in the same file?
- First turn the images into a PDF with the JPG to PDF tool and then merge the two PDFs.
- Is there a limit on files or size?
- WebFaz imposes no limit on the number of files. The practical limit is the memory of your computer or phone.
- Are my documents stored anywhere?
- No. The files are read and merged in the browser’s memory; when you close the tab, nothing remains.
