Below we show how to add whitespace padding to PDF documents online.

上傳您的文件

文件通過加密連接安全上傳. 文件保持安全. 處理後，它們將被永久刪除.

不想上傳您的文件並離線處理它們？
Try Sejda Desktop. 與在線服務功能相同，且文件永遠不會離開您的計算機.

點擊“上傳”並從您的本地計算機選擇文件.

將文件拖放到頁面上也有效.

Dropbox 或 Google Drive 文件

您也可以從 Dropbox 或 Google Drive 中選取 PDF 文件.

展開“上傳”下拉菜單並選擇您的文件.

Step 2: Margin size

Type a value for the page size, in inch. Use the up/down arrows to change.

The page preview will update, showing the margin added to the PDF pages.

Tip: Apply to all pages in the document or just a few

You can specify only few pages that need the margin. Click on the page thumbnails to select them.
