FAQ
Is there a file size limit?
Since all processing happens in your browser, the only limit is your device's available memory. Most devices can handle PDFs up to several hundred MB. Very large files may take longer to process.
How many PDFs can I merge?
There is no fixed limit on the number of PDFs you can merge. The practical limit depends on your device's memory and the size of each file. Most devices can easily merge 10-20 PDFs at once.
Gộp PDF có làm giảm chất lượng không?
Không, việc gộp PDF không làm giảm chất lượng nội dung. Công cụ sử dụng thư viện pdf-lib để sao chép nguyên vẹn các trang từ file gốc sang file gộp. Hình ảnh, văn bản, font chữ và định dạng đều được giữ nguyên 100%.
