❓ FAQ

Are my PDF files safe? +
Yes! All processing happens entirely in your browser using JavaScript. Your files are never uploaded to any server, so they remain 100% private.
What is the maximum file size? +
There is no hard server limit since processing is local. However, very large files (100MB+) may be slow depending on your device's RAM and CPU speed.
Can I merge more than 2 PDFs? +
Yes! You can add as many PDF files as you need. Drag to reorder them before merging.
How do page ranges work in Split? +
Enter ranges like "1-3, 5, 7-10" — each range becomes a separate PDF. Single numbers extract one page. Ranges must not exceed your document's page count.
What does "Bundle as ZIP" mean? +
When splitting into multiple files, they can be packaged into a single ZIP archive for easy download. Uncheck the option to download each PDF separately.
