Add Image Stamp to PDF
Apply a logo or stamp image to every PDF page
Add Image Stamp to PDF — what it does
Apply a logo or stamp image to every page of a PDF, choosing a corner or centre position, a width and an opacity. Repeating a mark across a whole document is exactly the kind of task that is unbearable page by page and trivial when applied in one pass.
When this tool helps
- Branding a proposal or report with a company logo on every page.
- Applying an APPROVED, PAID or CONFIDENTIAL stamp across a document.
- Adding a light diagonal mark to preview copies of a document before final release.
How to use it
- Choose the PDF file.
- Select the stamp or logo image.
- Choose position, width and opacity.
- Process and download the stamped PDF.
Accuracy, limits, and good practice
- Use a PNG with a transparent background, or the stamp arrives inside a visible white rectangle.
- Low opacity in the centre reads as a watermark; full opacity in a corner reads as branding. Pick the one you actually mean.
- Check a text-dense page before finalising — a centred stamp at high opacity can make body text hard to read.
Frequently asked questions
Can I stamp only some pages?
The stamp applies to every page. Split the document, stamp the part you need, and merge it back for selective stamping.
Does it work with a JPEG?
It does, but the white background comes with it. A transparent PNG is the right format for stamps.
How do I add text instead of an image?
The PDF watermark tool applies text across every page, and the header and footer tool places text in a fixed position.

PDF 加入圖片印章能做什麼
把商標或印章圖片套用到 PDF 的每一頁，可選擇角落或置中位置、寬度與透明度。同一個標記要蓋滿整份文件，正是那種逐頁做會讓人崩潰、一次套用卻毫不費力的工作。
什麼時候用得上
- 為提案或報告的每一頁加上公司商標。
- 在文件上蓋「已核准」、「已付款」或「機密」印章。
- 在正式發布前，為預覽版加上淡淡的斜向標記。
使用步驟
- 選擇 PDF 檔案。
- 選擇印章或商標圖片。
- 選擇位置、寬度與透明度。
- 執行處理並下載蓋章後的 PDF。
精確度、限制與實務建議
- 請使用透明背景的 PNG，否則印章會裝在一個看得見的白色方塊裡。
- 低透明度置中看起來是浮水印，高透明度放角落看起來是品牌標示，請選你真正想表達的那一種。
- 定稿前先看一頁文字密集的頁面——置中且不透明的印章可能讓內文難以閱讀。
常見問題
可以只蓋部分頁面嗎？
印章會套用到每一頁。需要選擇性蓋章時，請先拆分文件、蓋好需要的部分，再合併回去。
用 JPEG 可以嗎？
可以，但白色背景會一起帶進來。印章正確的格式是透明 PNG。
想加文字而不是圖片怎麼辦？
PDF 浮水印工具能在每頁加文字，頁眉頁尾工具則把文字放在固定位置。
