線上合併PDF
依您選擇的順序，將多個 PDF 合併為一份文件。
運作方式
1. Upload your file
Drag and drop or choose a PDF file from your device. You can add up to 20 files at once. Everything is checked against its real file type before processing starts.
2. We process it
Your file runs through an isolated job dedicated to 合併 PDF, with clear progress so you always know what stage it's at.
3. Download the result
Get your finished PDF file with one click. The original upload and the result are deleted automatically afterward.
您的檔案將保持私密
合併 PDF 會在獨立的處理程序中執行。您上傳的檔案與產生的結果會在下載時限結束後自動刪除——我們不會保留任何副本,下載連結也是隨機產生、僅限單次使用且會過期。
