Frequently Asked Questions
What is the difference between combine and merge?
For PDFs, "combine" and "merge" mean the same thing: joining multiple files into one. Some users prefer "combine" for simple assembly tasks, while "merge" often implies more control over order. This tool supports both use cases equally.
Can I combine different types of PDFs?
Yes. You can combine any valid PDF files—scanned documents, text-based PDFs, image-heavy PDFs, or mixed content. The tool preserves all content exactly as it appears in each source file.
Does combining reduce file quality?
No. The combination process copies pages without re-encoding. Quality, resolution, fonts, and embedded images remain unchanged.
Can I remove a file after adding it?
Yes. Hover over any file in the queue and click the X button to remove it. Use "Clear All" to start over completely.
Is there a limit to how many PDFs I can combine?
There is no artificial limit. The tool works with dozens of files depending on your device's available memory. Very large combined PDFs may take longer to generate but are fully supported.
