Frequently asked questions

How many PDFs can I merge at once?
There is no fixed cap. Merging is handled by your browser, so the practical limit is your device's memory — hundreds of typical PDFs are fine on a normal laptop.
Can I reorder the files before merging?
Yes. Drag any file in the list up or down to change its position before you click Merge.
Do you keep hyperlinks and bookmarks?
Internal page content, links and form fields are preserved. Bookmarks (the PDF outline) from each source file are not carried into the merged output.
Are my files uploaded to a server?
No. Files are processed directly in your browser using JavaScript and WebAssembly. Nothing is uploaded to our servers, so your documents never leave your device.
Does it work on mobile?
Yes. The tools run in any modern browser on desktop, tablet, or mobile (Chrome, Edge, Safari, Firefox). Very large files may be slower on low-end phones.
