About PDF Merge
Upload between 2 and 10 PDF files (each up to 20MB) in the order you want them in the final document. Click merge and we combine them into a single PDF on our servers. The merged file is ready to download; we do not store your files on our servers after processing, and they are deleted immediately after processing. Page order and quality are preserved so you get one continuous document from multiple sources. If the combined file is too large to email or upload, use our Compress PDF tool to reduce its size.
If the output is not what you expected, try a cleaner source file, then run the conversion again.
Edge cases
- Password-protected PDFs cannot be merged until unlocked.
- Some scanner-generated PDFs may fail parser compatibility.
Manual vs tool
Manual print-to-PDF workflows are slower and can reduce quality; merge keeps original pages.
Limitations
Corrupted or encrypted source PDFs may stop merge processing.
Practical tips
- Arrange files in final reading order before merging.
- Open merged file to verify page sequence immediately.
