添加图片水印 Word 文档 n8n

添加图片水印 Word 是一个 PDF4me 节点操作 n8n 将图像印在 Word 文档。使用此功能，无需打开任何文件，即可在对外发布的报告上添加公司徽标、在审阅前标记草稿，或为工作流程生成的每份合同添加保密标识。 Word。

此节点的功能

PDF4me Word添加图片水印 Word 需要两个输入，而不是一个： .docx 文件盖章和 图像 盖章到上面。每个都有自己的输入法下拉菜单，因此文档和水印可以通过不同的路径到达，例如来自先前节点的文档和从……获取的徽标。 URL尺寸由…… 规模 除非你明确设置。 宽度 或者 高度 以积分表示。

您不容错过的重要事实

两个输入框，两个下拉菜单

这 Word 文件和水印图像是分别配置的，各自使用不同的输入法选择器。如果只配置了一个而忘记配置另一个，这是节点拒绝运行的最常见原因。

宽度和高度均为 0 表示使用缩放

两个尺寸字段的默认值均为 0，这并非零尺寸水印，而是指示图像按缩放因子缩放。仅当需要精确尺寸时才在任一字段中输入数值。

使用透明 PNG

A JPEG 由于没有透明度通道，它的白色背景会覆盖下面的文字。 PNG 真正的透明度才能让水印看起来像水印，而不是粘贴的方框。

注意两种独立的输入方法： Word 文件到达 URL 水印图像来自前一个节点。宽度和高度均为 0，因此缩放比例 1 控制图像大小。

实用技巧

Start with a transparent PNG

Alpha transparency is what separates a watermark from a pasted rectangle. Export the logo with a transparent background before wiring it in.

Tune Scale before touching Width

Scale keeps the aspect ratio automatically. Reach for explicit point values only when a brand guideline demands an exact size.

Enable Semi-Transparent over body text

A full-opacity mark in the centre of a text page hides content. The toggle exists precisely for documents that are meant to stay readable.

Check the two input methods separately

The document and the image are configured independently, so a run can fail because the image source is unset while the Word source looks fine.

Verify one file before a batch

Open a single stamped document in Word and confirm placement and opacity, then run the workflow across the rest.

Keep the .docx extension

Both Document Name and Output File Name drive format handling. A missing or wrong extension causes confusing downstream failures.

常见问题

What image formats can I use as a Word watermark?+

Standard raster image formats work, and a PNG with a transparent background gives the cleanest result because page text stays visible around the logo. A JPEG has no alpha channel, so it stamps an opaque rectangle unless you also enable Semi-Transparent. The PNG specification covers the alpha channel behaviour that makes this work.

Why are Width and Height set to 0 by default?+

Zero means unset, not a zero-size watermark. When both are 0 the image is sized by the Scale factor, where 1 is its natural size. Entering a non-zero point value in either field overrides Scale, and supplying only one of the two preserves the aspect ratio by calculating the other.

Does the watermark appear on every page of the document?+

The action applies the watermark to the document rather than to a single page you nominate, so it suits stamping a whole file such as a contract or report. Run one representative multi-page document through the node and open the result in Word before rolling it out across a batch.

What is the difference between the image and text watermark actions?+

Add Image Watermark To Word stamps a picture such as a company logo or scanned seal and needs an image as a second input. Add Text Watermark To Word Document renders a word or phrase you type, so it needs no image file and is easier to vary per run with an expression.

Can I watermark many Word files in one n8n run?+

Yes. The node processes one document per item, so feed it a list of files from a trigger, a folder listing, or an n8n looping node and the action executes once per item. The same watermark image can be reused across the whole run.
