Merge PDF files

What Merge PDF is for

Merge PDF is the digital stapler. Cover letter, form, ID scan, and appendix become one attachment. Order matters: the first file you add is the first section unless you reorder before you convert.

Use merge after JPG to PDF when photos need to sit with a typed PDF. Split first if you only need some pages from a long file, then merge those extracts with another document.

How to use Merge PDF

Use merge after JPG to PDF when photos need to sit with a typed PDF. Split first if you only need some pages from a long file, then merge those extracts with another document.

1. Stay on the Merge PDF page.
2. Add a PDF file. Drag it onto the box or browse from your device.
3. Click Merge PDFs and wait until it finishes.
4. Download the PDF file. Check it before you send it.
5. Save your own copy. Uploads are removed within about an hour.

What to expect in the PDF file

The PDF file is a working copy, not always a pixel-perfect twin. Simple documents fare better than heavy design. That is true of every converter, including desktop software.

Related tools next to Merge PDF include Split PDF, Organize PDF, JPG to PDF, Split PDF, Extract pages, Delete pages. Use them for the step before or after this conversion.

Limits and files we accept

Use the file types the picker allows. The size cap is 50 MB. Word, Excel, PowerPoint, PDF, and image jobs are all in the same toolkit — pick the tool that matches the file in your hand.

Password-protected, damaged, or huge scans fail more often than a normal export from Word. Compress, Repair PDF, Unlock PDF, or OCR usually fixes the next try.

If something goes wrong

Work through this list before you assume the tool is down:

• The file is a scan, not text — run OCR.
• The PDF is password-protected — unlock it with a password you know.
• The upload is too large — compress, then retry.
• The PDF is damaged — try Repair PDF.
• Layout looks off — common on newsletters and magazines; check tables and text boxes.

Practical tips

• Prefer a digital PDF file over a photo of a screen.
• Stay under 50 MB, or compress first.
• Open the PDF result on your computer before you email it.
• Do not upload files you do not have the right to convert.
• When you are done editing, Word to PDF, Merge PDF, or Compress PDF can prepare the file to send.
• You can add more than one file on this tool.

Related workflow

A common path is PDF to Word to edit, then Word to PDF to send. Another is JPG to PDF, then Merge PDF, then Compress PDF for email. OCR belongs first when the PDF is a photo of a page.

Merge PDF is one job. The rest of the toolkit — convert from PDF, convert to PDF, organize pages, compress, protect, and OCR — is there so you can finish the file without starting over.
