Merge PDF
Combine several PDFs into one, in any order — free, no upload.
How it works
Combine several PDFs into one document. Add your files, drag them into the order you want using the arrows, and download the merged PDF. Pages keep their original quality — nothing is re-encoded.
🔒 Your file is processed entirely in this browser — it is never uploaded to a server. No signup, no watermark, no page limits.
🔒 Your document never leaves your device: unlike most online PDF tools, which upload your file to their servers, everything here runs locally in your browser. There is no upload, no account, no watermark and no page or file-count limit — so it's safe for contracts, invoices, medical records and anything else confidential.
About the Merge PDF
This free PDF merger combines several PDFs into a single document — useful for stitching together scanned pages, bundling invoices, or assembling chapters and reports into one file. Add your PDFs, put them in the order you want, and download the merged result.
Unlike most online PDF tools, your files are never uploaded: the merge happens entirely in your browser, so confidential documents stay on your device. No signup, no watermark, no limit on how many files you combine.
How to merge PDF files
- Choose or drag in two or more PDFs.
- Reorder them with the up and down arrows until the sequence is right.
- Click Merge, then download the combined PDF.
Why merge PDFs in your browser
- Contracts, invoices, payslips and medical records never leave your device.
- No file-size or file-count caps imposed by a server.
- Pages are copied as-is, so quality and selectable text are preserved.
Frequently asked questions
How do I combine multiple PDFs into one?
Add all the PDFs you want to join, arrange them in the order you'd like using the arrows, then click Merge and download the single combined file.
Is there a limit on how many PDFs I can merge?
No. Because merging runs in your browser rather than on a server, there's no imposed file-count or size limit — only your device's available memory.
Are my files uploaded to a server?
No. The merge is performed locally in your browser, so your documents never leave your device. That makes it safe for confidential files.
Does merging reduce the quality of my PDFs?
No. Pages are copied across without re-encoding, so text stays selectable and images keep their original quality.
Can I change the page order after merging?
Set the file order before merging using the arrows. To rearrange individual pages afterwards, use the Split and Merge tools together, or remove pages with the Remove Pages tool.
