Merge PDF
Combine two or more PDFs into a single file before you send a packet, archive a case, or insert one clean attachment into Word. Files are joined in the order you select them in the file picker.
Your file is processed entirely in your browser. It is never uploaded to any server.
How to merge PDF files: step by step
- Click the file field and select every PDF you want in the final document. Hold Ctrl/Cmd to pick several at once.
- Confirm the selection order matches the order you want (many browsers list files in the order clicked).
- Click Merge PDFs and save
merged.pdf. - Open the result briefly to verify page breaks between source documents look right.
Why merge here instead of printing to PDF repeatedly
“Print to PDF” from Word or a browser can flatten forms and drop bookmarks, and stitching with a printer driver often re-encodes pages. This tool copies pages with pdf-lib in the browser, so you keep vector text when the source has it, without another upload site in the chain.
Converting a Word document to PDF first
This tool merges PDFs, not Word files, so a .docx needs to become a PDF before it can join the merge. In Word (desktop or Google Docs), use File → Save As (or Export) and choose PDF, which keeps text, fonts, and hyperlinks intact, unlike printing through a virtual printer driver. Once you have a PDF from each source file, select them all here in the order you want and merge.
Frequently Asked Questions
Can I reorder pages after merging?
This tool merges whole files in selection order. To rearrange, split out pages first or re-select files in the desired sequence.
Do bookmarks and forms survive?
Page content is copied; advanced interactive features may not carry over completely. Check critical forms after merging.
Is there a file count limit?
Only what your browser memory can handle. Very large scans may need compression before a big merge.
Can I merge a PDF into an existing Word document?
This tool combines multiple PDFs into one PDF first. To bring that into an existing Word document, merge the PDFs here, then use Insert as Object or Insert as Image on the merged file so everything arrives as one unit instead of several separate inserts.
Can I insert a Word document into a PDF for free?
Yes, in two free steps. First save the Word file as a PDF (File → Save As → PDF in Word, or File → Download → PDF in Google Docs). Then select that PDF alongside your other PDF(s) here and merge; both steps are free and need no extra software.
Can I merge Word and PDF into one file for free?
Yes. Export the Word document to PDF first (Word and Google Docs both do this natively at no cost), then merge it with your existing PDF here. The output is a single PDF containing both documents in the order you selected them.
Can I convert Word to PDF without losing formatting?
Word's built-in Save As → PDF (or Export) renders the document the same way it prints, so fonts, spacing, and page breaks carry over intact. Avoid routing through a separate "virtual printer" PDF driver, since those re-rasterize the page and are more likely to shift layout.
Does converting Word to PDF keep hyperlinks intact?
Yes, when you use Word's native Save As → PDF or Export command, clickable links carry over by default. Printer-driver PDF converters frequently flatten links into plain text, so stick with the built-in export if you need them to stay clickable.
Can I convert a Word document to a fillable PDF form?
Not with Word's export alone: Save As → PDF flattens the page, it does not create interactive form fields. You need a PDF form editor such as Adobe Acrobat's Prepare Form tool to add fillable fields afterward. We do not offer form-field creation in the browser yet.
Can I convert Word to PDF/A archival format?
Word itself does not export true PDF/A. On Windows, Acrobat's Save As Other → Archivable PDF (PDF/A) adds the required compliance; LibreOffice's Export Directly as PDF/A is a free alternative if you have that installed. We do not include a PDF/A encoder in these browser tools.
Can I convert Word to a password-protected PDF?
Yes, but not here: we do not encrypt PDFs in the browser yet. On Windows, use Word's Save As → PDF → Options → Encrypt the document with a password. On Mac, or if you need stronger encryption, Adobe Acrobat's Protect tool can add a password after export.
Can I batch convert multiple Word files to PDF?
Word itself has no built-in batch export, so each file needs its own Save As → PDF, or a scripted approach like Power Automate/a macro if you convert dozens regularly. Once you have the individual PDFs, select them all here to merge into one file in the order you pick them.
