Frequently Asked Questions
Can I merge more than two PDFs at once?
Yes, you can add as many PDF files as you need. Just upload them all and reorder them using the arrows before merging.
Is there a file size limit?
There's no hard limit. Because processing happens in your browser, very large files may be slower depending on your device's memory.
Will the merged PDF lose quality?
No. CliqTools uses pdf-lib to combine pages at full fidelity — images, fonts, and formatting are preserved exactly as they are in the originals.
Do my files get uploaded to a server?
Never. All merging is done in your browser using JavaScript. Your files don't leave your device at any point.
Can I reorder pages before merging?
Yes — use the up and down arrows next to each file to set the order before you click Merge.
