Frequently Asked Questions
Are my files uploaded?
No. We use a powerful library called `pdf-lib` to merge your documents right inside your browser. Your files never leave your device.
Can I rearrange file order?
Yes! Simply drag and drop the files in the list to change their sequence before merging.
Is there a file size limit?
Technically none! Since it runs on your computer, the only limit is your device's available memory (RAM). You can typically merge dozens of large files without issue.
