Frequently Asked Questions
Is it safe to merge PDFs here?
Yes. ArmorPDF processes everything in your browser using JavaScript. Your files never leave your device and are never uploaded to any server.
How do I combine PDF files without uploading them?
Just drag and drop your PDF files into ArmorPDF. All processing happens locally in your browser, so no files are ever sent to a server.
Can I rearrange pages before merging?
Yes! After adding your files, you can drag and drop them to change the order before merging.
Is there a file size limit?
There is no file size limit. Large files may be slower to process since everything runs in your browser.
Does this work on iPhone and Android?
Yes. ArmorPDF works in any modern browser on any device, including iPhones, iPads, and Android phones.
Do I need to install anything?
No installation needed. ArmorPDF runs entirely in your web browser. Just open the page and start merging.
