Frequently Asked Questions about Merging PDFs
Is it safe to merge my PDF files with this tool?
Yes. This is the most secure way to merge PDFs online. Your files are **never sent to a server**. All processing is done on your own computer, so your data remains 100% private and is never seen by anyone but you.
Can I reorder the files before I merge them?
Absolutely. After you add your files, you can simply drag and drop the file previews in the upload area. This allows you to set the exact order you want them to appear in the final, merged document.
Will I lose quality when I combine PDFs?
No. Our tool combines the PDF files without re-compressing or altering the original pages. Your document quality, including images, text, and layout, will be preserved perfectly.
How many PDF files can I merge at once?
You can merge multiple PDF files. While there's no set limit, performance depends on your computer's memory, as all processing is done locally. For most users, combining 10-20 files at once is fast and efficient.
