Frequently asked questions
Does this upload my PDF anywhere?
No. All processing uses pdf-lib and PDF.js running entirely in your browser — your files never leave your device.
Can I chain multiple edits?
Yes. Reorder pages, then split out a range, then merge another document — each operation stacks with full undo.
How does the Split tool work?
Click pages in the viewport to select them, or type a range like '1-3, 5'. Click Extract to keep only those pages as a new document.
How does Merge work?
Select the Merge tool and add PDF files. They are appended after the current document in the order listed. Drag to reorder them before merging.
How do I delete a single page?
Select the Reorder tool and click the × button on any page thumbnail to remove it.
