FAQ
Is there a file size limit?
No — merging is done entirely in your browser using PDF.js. The limit is your device's available RAM, which handles most normal PDFs without issue.
Does merging PDFs reduce quality?
No — PDF merging combines files at the document level without re-encoding content, so images and text stay at their original quality.
Can I reorder pages before merging?
Yes — drag the PDF cards to reorder them before clicking Merge.
