Frequently asked questions
Is there a limit on how many PDFs I can merge?
No fixed limit. Very large documents are limited only by your device’s memory.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly. Your files never leave your device, so it is safe for private photos, contracts and business data. Once the page has loaded it even works offline.
Is it free? Are there limits?
It is free, with no sign-up, no watermark and no daily limits. Because nothing is uploaded there is no upload size limit either; the only limit is your device’s memory, which matters mostly for very large videos.
