Frequently asked questions

Is there a limit on the number of files?

No fixed limit. Merging happens on your device, so very large jobs depend on your computer's memory.

Will the quality change?

No. Pages are copied as-is, so text, images and links keep their original quality.

Is Merge PDF free?

Yes. Merge PDF is free to use with no sign-up and no watermark.

Are my files uploaded to your server?

No. All processing happens locally in your browser using JavaScript and WebAssembly. Your files never leave your device, which also makes it fast and private.

Does it work on my phone?

Yes. It works in any modern browser on Windows, Mac, Linux, Android and iPhone. Very large files may be slow on older phones.
