Frequently Asked Questions
Is this PDF merger really free?
Yes, 100% free with no limits and no watermark. Most online merge tools cap you at 1–2 tasks per day or charge a monthly subscription; this tool runs entirely in your browser, so there is nothing to pay for.
Do my files get uploaded to a server?
No. Your PDFs are combined directly inside your browser using local processing — nothing is uploaded, stored, or seen by anyone. This makes it safe for tax documents, contracts, and resumes.
How do I merge PDFs?
Select two or more PDF files, drag the list items into the order you want (or use the up/down arrow buttons), then click "Merge PDFs". The combined PDF downloads instantly — the whole process takes under a minute.
Can I reorder files before merging?
Yes. Drag file rows to change the document order, or use the arrow buttons on each row — the merged PDF comes out in exactly the sequence you set, with page counts shown per file.
Does it work on my phone?
Yes. The tool works in any modern browser on iPhone, Android, tablets, and desktops — no app install needed.
