Frequently asked questions
Are my files uploaded to a server?
No. Every PDF tool here runs entirely in your browser — your files never leave your device.
Is there a file limit?
There's no hard limit, but very large files use more memory since everything runs locally.
Can I change the order of the PDFs?
Yes — files merge in the order listed, so add them in the sequence you want (or re-add to reorder).
