About this tool
Merging is one of the most common PDF tasks: combining a cover letter with a resume, stitching together scanned pages from different sessions, or assembling a set of reports into one document to send. This tool copies every page from each PDF you add into a new document, preserving the original content exactly.
The order you arrange your files in is the order they'll appear in the final PDF — reorder them with the arrow buttons before merging. Because the merge runs with a PDF library inside your browser, no file is ever transmitted to an external server.
Why use it
- Combine any number of PDFs into one
- Full control over page order before merging
- Original page content and formatting preserved
- No file size restriction from a server upload
- PDFs are merged locally — never uploaded
Frequently asked questions
How many PDF files can I merge at once?
There's no fixed limit — add as many files as you need. Very large batches are only limited by your device's memory.
Will merging affect the quality or formatting of my PDFs?
No, pages are copied directly from each source document, preserving their original content, fonts and formatting.
Can I merge password-protected PDFs?
Not directly — remove the password from each file first using your PDF reader, then merge them here.
Can I change the page order after merging?
Set the order before merging using the arrow buttons; if you need to adjust it afterward, use the Split PDF tool to extract and rearrange pages.
Is this really free with no limits?
Yes, merging is free with no watermark, no page limit, and no signup required.
