About this tool
Quotations, invoices, supporting documents — sending one PDF is cleaner than five attachments. Add your files, arrange the order and merge them into a single PDF. Pages are copied without re-rendering, so text stays selectable and quality is unchanged.
Good to know
- Password-protected PDFs are not supported.
- Bookmarks/outline and some form fields are not preserved.
Frequently asked questions
Does merging reduce quality?
No. Pages are copied as they are, including text and vector graphics.
Can I merge encrypted PDFs?
PDFs that require a password to open cannot be merged. Remove the protection first.
Are bookmarks and form fields kept?
Page content is kept. Document-level bookmarks and interactive form fields may not carry over.
Is Merge PDF private?
Yes. This tool processes files entirely in your browser, so your files are not uploaded to our servers.
