FAQ
What order will the merged PDF be in?
Files are merged in the order shown in the list. You can reorder them by dragging.
Are there file size limits?
No hard limit, but browser memory constraints apply. We recommend keeping individual PDFs under 100MB. Please be patient when merging multiple large files.
Are my files uploaded to a server?
No. All ToolZen tools run locally in your browser. Your files never leave your device.
