Frequently Asked Questions
How to merge PDF files for free?
Drop your PDFs above, arrange them in the desired order, and click 'Merge PDFs'. Your files are processed entirely in your browser — they never leave your device. No account, no upload, no limits.
Is it safe to merge PDFs online?
With pdfprivately — yes. Unlike other online tools that upload your files to their servers, we process everything client-side using WebAssembly. You can verify this by disconnecting your internet after the page loads — merging still works.
Can I merge PDFs in any order?
Yes. Drag and drop to reorder files before merging. The first file in the list will be the first page of the merged PDF.
