Frequently Asked Questions

Everything you need to know about merging PDFs online.

How do I merge PDF files online for free?
Upload your PDFs to this page, drag them into the order you want, then click Merge & Download PDF. The combined file is ready in seconds. No account, no payment, no file size restrictions imposed by this tool.
Are my files uploaded to a server when I use this tool?
No. QwikMerge runs entirely inside your browser using JavaScript and the pdf-lib library. Your PDF files are never sent over the internet to any external server. This makes it safe for confidential, sensitive, or personal documents.
Will the merged PDF have any watermark?
No watermarks are added at any point. QwikMerge never stamps a logo, URL, or any branding onto your document. The PDF you download is a clean, professional file identical to the quality of your originals.
How many PDF files can I merge at once?
There is no hard limit set by this tool. You can combine as many PDFs as your device memory allows. Most users merge 2 to 30 files without any issues. Very large sets of files may take a few extra seconds to complete.
Can I change the order of files before merging?
Yes. Once uploaded, each file appears in a numbered list. Drag any row up or down to change its position. The final merged PDF will follow exactly the order shown in the list when you click download.
Will merging reduce the quality of my PDFs?
No quality is lost. Text, vector graphics, embedded fonts, and images are copied directly from the source PDFs into the merged document. There is no re-rendering or compression applied during the process.
Does this work on iPhone, iPad, or Android?
Yes. QwikMerge works in any modern browser including Safari on iPhone and iPad, and Chrome or Firefox on Android phones and tablets. You can also install it as an app from the Install button at the bottom of the screen.
