Frequently Asked Questions
How do I merge multiple PDFs into one?
Upload all the PDF files you want to combine, drag to rearrange their order if needed, then click the Merge button. Your combined PDF will be ready to download instantly.
Can I reorder pages before merging?
Yes! After uploading multiple files, use the arrow buttons or drag-and-drop to change the sequence before combining.
Is there a limit to how many files I can merge?
You can merge up to 50 PDF files at once. Keep the total batch under 100MB for best browser performance.
Will merging reduce my PDF quality?
No. The merger losslessly combines files — resolution, fonts, and images remain exactly as in the originals.
Are my files safe?
Yes. All processing runs locally in your browser. Your files are never uploaded to our servers.
