Common questions
Is there a file size limit?
There's no hard limit. Since everything runs in your browser, it depends on your device's memory. Most users can merge dozens of PDFs without issues.
Does it preserve links and bookmarks?
Yes, the tool copies pages directly so internal links, annotations, and formatting are preserved.
Can I reorder pages within a PDF?
Currently you can reorder entire files. Page-level reordering within a single PDF is planned for a future update.
