Frequently Asked Questions
Is it safe to merge PDFs with this tool?
Yes, absolutely. All PDF processing happens entirely in your browser using client-side JavaScript. Your files are never uploaded to any server, which means your documents stay completely private and secure on your device.
Is there a limit on the number of PDFs I can merge?
There is no hard limit on the number of files. You can merge as many PDFs as your browser can handle. However, very large files may take longer to process since everything runs locally in your browser.
Can I reorder the PDFs before merging?
Yes! After adding your PDF files, you can use the up and down arrow buttons next to each file to rearrange the order. The merged document will follow the order you set.
What happens to the original PDF files?
Your original files are not modified in any way. The tool reads your PDFs, creates a new merged document, and provides it for download. The originals remain unchanged on your device.
