PDF Page Background
Add a solid color background behind selected PDF pages
PDF Page Background — what it does
Add a solid colour background behind the content of selected PDF pages, specified with a page range. The colour sits underneath the existing text and graphics, which is what distinguishes a background from a stamp painted over the top of the page.
When this tool helps
- Tinting section divider pages so they stand out in a printed bundle.
- Adding a coloured background to a cover page without recreating the document.
- Marking draft or internal pages with a tint that is obvious even in a photocopy.
How to use it
- Choose the PDF file.
- Enter the page range to affect.
- Pick the background colour.
- Process and download the result.
Accuracy, limits, and good practice
- Very light tints are the safe choice — a saturated background drains printer ink and can leave black text hard to read.
- Check contrast if the page carries dark text: legibility on screen is not the same as legibility on paper after photocopying.
- For a mark that sits over the content instead of behind it, the watermark or image stamp tools are the right choice.
- Test-print one tinted page before applying the colour to a long document; screen colour and printed colour diverge most in pale tints.
Frequently asked questions
Will the background hide existing content?
No, it is drawn behind the page content, so text and images remain visible on top of it.
Can different pages have different colours?
One colour per pass. Run the tool again with another range and colour for a second section.
Does this increase the file size?
Only marginally. A solid colour fill adds very little data per page.
Does a background print on every printer?
Some drivers skip background graphics by default. Check the printer's settings if a tinted page comes out white.

PDF 頁面背景能做什麼
為指定頁面範圍的 PDF 內容後方加上純色背景。顏色位於既有文字與圖形之下，這正是「背景」與「蓋在頁面上方的印章」之間的差別。
什麼時候用得上
- 為分隔頁上色，讓它在列印的卷宗中一眼可辨。
- 為封面加上底色，不必重做整份文件。
- 為草稿或內部頁加上即使影印也看得出來的底色。
使用步驟
- 選擇 PDF 檔案。
- 輸入要套用的頁面範圍。
- 選擇背景顏色。
- 執行處理並下載結果。
精確度、限制與實務建議
- 非常淺的色調最安全——高飽和背景既耗墨，也可能讓黑色文字難以閱讀。
- 頁面有深色文字時請檢查對比：螢幕上的可讀性，不等於印出來、影印後的可讀性。
- 若要的是蓋在內容上方的標記，請改用浮水印或圖片印章工具。
- 套用到長文件前，請先試印一頁上色的頁面；淺色調正是螢幕色與印刷色差距最大的區間。
常見問題
背景會蓋住既有內容嗎？
不會，它繪製在頁面內容之下，文字與圖片仍顯示在上方。
不同頁面可以用不同顏色嗎？
一次一種顏色。第二個段落請用另一組範圍與顏色再執行一次。
檔案會變大嗎？
只會略為增加。純色填滿每頁增加的資料量非常小。
每台印表機都會印出背景嗎？
有些驅動程式預設略過背景圖形。上色頁印出來是白的，請檢查印表機設定。
