Frequently Asked Questions

Are my files uploaded to a server?

No, merging happens entirely in your browser — files never leave your device.

Is there a limit to how many files I can merge?

You can merge up to 30 files at once, with a combined size limit of 150MB — plenty for most everyday merging needs.

Is there a file size limit?

Very large files may be slower since processing happens in your browser, but there's no fixed limit.

Are my files uploaded to a server?

No. Merging happens entirely in your browser using JavaScript — your PDFs are never uploaded or stored anywhere.
