Frequently Asked Questions
Are my PDFs uploaded to a server?
No. All PDF processing happens entirely in your browser using pdf-lib. Your files never leave your device - complete privacy guaranteed.
Is there a file size limit?
There's no hard limit, but very large PDFs (100+ MB) may be slow depending on your device's memory. Most documents process instantly.
Can I merge PDFs with different page sizes?
Yes, the tool preserves each page's original size and orientation. You can merge portrait and landscape PDFs together.
How do I reorder pages before merging?
After uploading, drag and drop the file cards to reorder them. The merged PDF will follow your specified order.
Can I extract specific pages from a PDF?
Yes, use the Split mode and specify page ranges (e.g., '1-3, 5, 7-10') to extract only the pages you need.
