Free PDF Merger — Combine Multiple PDFs Into One File
Combine multiple PDF files into a single document entirely within your browser. Hephio's PDF merger processes everything locally — your files are never sent to a server, keeping your documents completely private, perfect for merging sensitive files.
Merging PDFs is a constant need: combining scanned documents into a single file, assembling a multi-section report, consolidating invoices and receipts for accounting, or packaging multiple attachments into one clean file for email. Having everything in one PDF is easier to share and more professional.
Add your PDFs in any order, rearrange them using the file list, then merge and download in one click. The process is fast and there are no file size restrictions.

Frequently Asked Questions
Is there a limit on how many PDFs I can merge?
There's no server-side limit. You can merge as many files as your browser's available memory allows.
Will merging PDFs affect the quality of images inside them?
No. The tool combines the PDF files as-is without re-encoding or recompressing any content. Image and text quality is fully preserved.
Can I reorder individual pages from different PDFs before merging?
You can reorder the files before merging. To reorder individual pages across combined documents, use the Rearrange tool after merging.
