Why Merge PDF Files Online?
Managing multiple separate PDF documents can quickly become cluttered and inefficient, especially when submitting reports, sharing portfolios, or emailing attachments. Merging your PDFs into a single document makes files easier to share and review.
Our online PDF merger lets you combine up to 10 PDF files and reorder them in the list before merging. Processing runs in your browser, so files are not uploaded to a cloud server for merging.
Key Features & Benefits
Designed for simple file combining, local processing, and clear limits:
Private & Browser-Based
Merging runs locally in your browser. Files are not sent to a server for processing.
Merge Up to 10 Files
Combine 2 to 10 PDF files in one session, free and without registration. Each file can be up to 20MB.
Pages Copied As-Is
Pages are copied into the new PDF without re-compressing them as images, so text and layout are generally preserved. Bookmarks and some interactive features may not carry over.
Easy File Arrangement
Drag files in the list to set the merge order. This reorders whole files, not individual pages inside a file.
