Frequently Asked Questions
Is there a limit to how many PDFs I can merge?+
There is no hard limit, but very large files may take longer to process since everything runs in your browser.
Will the merged PDF preserve formatting?+
Yes, all pages are copied exactly as they appear in the original files. Formatting, images, and text are fully preserved.
Can I reorder pages before merging?+
You can reorder the files using the up/down arrows. For page-level reordering within a file, use the Split tool first.
