Frequently Asked Questions
How many PDFs can I merge at once?
There is no hard limit, but it depends on browser memory. It is recommended to keep the total size of merged files under 50MB for stability.
Will the merged PDF be compressed?
No. Merging only concatenates pages. The content, clarity and quality of the original pages stay unchanged.
Are my PDFs uploaded to a server?
No. All merging happens locally in your browser. Files never leave your device.
Can I adjust the order after merging?
Yes. The file list supports drag-to-reorder after upload. Reorder and merge again to output in the new order.
