Frequently asked questions

How do I merge PDF files?

Select two or more PDF files using the "Add files" button. Reorder them with the arrow buttons. Click "Merge" to combine them into a single PDF that downloads automatically.

How do I extract specific pages from a PDF?

Switch to the Split tab, select a PDF, then enter the page range (e.g. 1-3, 5, 7-10). Click "Extract pages" to download a new PDF containing only those pages.

Are my PDFs uploaded to a server?

No. All processing happens in your browser using pdf-lib. Your files never leave your device.

Is there a file size limit?

The limit depends on your browser's memory. Files up to 50 MB work well on most devices.
