Frequently Asked Questions

Yes — completely free with no sign-up, no watermarks, and no file size or page limits. The tool is supported by ads, not user fees.
Completely. All merging happens inside your browser using JavaScript. Your files are never uploaded to any server and never leave your device.
There is no set limit on the number of files. You can merge as many PDFs as you like. Performance depends on your device — very large collections of big files may take longer on older hardware.
Yes — pages are copied directly from the source PDFs without re-rendering, so formatting, images, fonts, and quality are all fully preserved in the merged output.
The tool will attempt to merge encrypted PDFs but may not be able to read all protected files. If a file fails to load, try removing the password protection first using a dedicated PDF unlock tool, then merge.
