, when there are dozens or even hundreds of PDF copies in hand that need to be uniformly watermarked with internal, confidential, sample or TEST, it is very time-consuming to open the files one by one, and it is easy to miss the files. This article HeSoft Doc Batch Tool For example, demonstrate how to add watermark function through PDF, import multiple PDF files at a time, set text watermark content, rotation angle, tiling method and density, and complete batch processing according to the wizard, helping users to quickly complete multiple PDF unified watermarking tasks.
In daily office, PDF is often used in contracts, reports, training materials, project documents, bid documents, review drafts and other scenarios. In many cases, text watermarks need to be added to documents before they are sent to the outside world or circulated internally, such as "internal data", "for review only", "test", "sample manuscript", "confidential document", etc. If there is only one or two PDF, it is acceptable to open and edit manually. However, when the number of files becomes dozens or hundreds, adding watermarks one by one is not only time-consuming, but also prone to problems such as missing processing of a PDF, inconsistent text position, inconsistent transparency, etc.
This article is to solve the problem of "adding text watermark to many PDF in batch. The following will combine screenshots HeSoft Doc Batch Tool This office software is an example to explain how to enter the PDF watermark function, import multiple PDFs, set text watermark parameters, and finally get a PDF file with a unified text watermark. The entire process is suitable for users who want to reduce repetitive operations and improve document processing efficiency.
Applicable scenarios: Under what circumstances do you need to batch PDF to add text watermarks
the requirement of batch PDF with text watermark is very common, especially suitable for office scenes with large number of files, unified format and the same processing rules. For example, enterprises need to add "for customer reference only" watermarks to a batch of PDF reports issued to the outside world. Legal or administrative departments need to add "draft" or "archived version" to the contract PDF. The training department needs to add the company name or internal number to the courseware PDF. Design, audit, finance, project management and other positions, it is also often necessary to add text watermarks such as "TEST", "Confidential" and "Sample" to PDF documents.
If you use the traditional method, you need to open the first PDF, add a watermark, and save it. Then open the second PDF and repeat the settings. Repeat the same action for each subsequent file. The more documents, the more obvious the duplication of labor. Using the batch processing function in office software, you can change "one by one processing" to "one setting and batch execution", which is the core value of document batch processing tools.
Effect Preview: Before processing, PDF has no text watermark, and after processing, TEST watermark
appears.From the file list before processing, it can be seen that there are multiple PDF files in the directory to be processed, which are 1.pdf, 2.pdf, 3.pdf, and 4.pdf respectively. This kind of situation is very common in the actual office: the same batch of documents need to use the same watermark rules for unified processing.
open the PDF page before processing, you can see that the body content is a normal report page, and there is no obvious text watermark in the page. The position pointed by the red arrow also indicates that the content area of the page is still in the original state, and no logo such as "TEST" is superimposed.
after the processing is completed, open the PDF for viewing, and you can see that the "TEST" text watermark with light red and oblique display has appeared on the page. The watermark is covered on the page content in a tiled manner, which can not only play the role of identification and anti-random transmission, but also will not completely block the text reading. This indicates that the batch addition of text watermarks has taken effect.
Operation steps: use PDF watermark function to batch process multiple PDFs
.step 1: enter PDF tool and select PDF watermark function
open HeSoft Doc Batch Tool After that, you can see multiple tool categories on the left, such as home page, task flow, all tools, file name, folder name, file sorting, Word tool, Excel tool, PowerPoint tool, PDF tool, etc. Since this is a PDF file to be processed, you need to enter the "PDF Tools" category on the left.
In the PDF tool page, you can see multiple PDF-related function cards, such as PDF removal password protection, PDF conversion to Word, PDF conversion to TXT, PDF addition page margins, etc. What you want to achieve this time is to add watermarks to multiple PDFs, so select the "PDF Add Watermark" function. The description of the function card in the screenshot is "Add text or image watermarks to PDF files in batches", which exactly corresponds to the requirements of this article.
the purpose of this step is to enter the correct batch processing module. After selecting the function, the software will enter the wizard operation page of adding watermark to PDF, and the subsequent steps only need to be completed in turn according to the page steps.
Step 2: Import PDF files that need to be added with text watermarks
after entering the "PDF Add Watermark" page, the processing flow is displayed at the top of the interface: select the records to be processed, set the processing options, set the save location, and start processing. You are currently in Step 1 "Select Records to Process". At the top right of the page, you can see buttons such as "Add File", "Import File from Folder", "Empty" and "More.
If the number of PDFs is small, you can click "Add Files" to add the PDFs to the list one by one. If the PDFs are all in the same folder, you can use "Import Files from Folder", which is more suitable for batch processing. Four PDF files have been imported in the screenshot. The list displays information such as serial number, name, path, extension, creation time, and modification time. The names are 1.pdf, 2.pdf, 3.pdf, and 4.pdf respectively, and the extension is pdf.
the expected result of this step is to have all PDFs that need to be watermarked with text appear in the list. After importing, it is recommended to check whether the number of records is correct. "Number of records: 4" is displayed at the bottom of the screenshot, indicating that the same watermark settings are currently implemented for 4 PDFs. After confirmation, click "Next" at the bottom to enter the processing option settings.
Step 3: Select the text watermark and fill in the watermark text
after entering step 2 "Set processing options", you first need to select the watermark type. The watermark type is displayed on the interface, and text watermark and image watermark are available. Since the goal of this article is to add text watermarks to PDFs in batches, select Text Watermark ". Text Watermark has been selected in the screenshot.
In the Watermark Text input area, you can fill in the text content that you want to add to the PDF page. The screenshot is filled in "TEST". In actual use, it can be changed to "internal data", "for review only", "company name", "sample draft", "Confidential" and so on according to business needs. It should be noted here that all imported PDF will use the same watermark text, so you should carefully check whether the text is correct before clicking Next to avoid rework after batch processing.
the purpose of this step is to determine the type and core content of the watermark. As long as the text watermark is selected and the watermark text is filled in, the subsequent generated PDF will be superimposed with the text mark according to the content.
Step 4: Set the rotation angle, filling method and tiling density
in the same processing options page, you can also see many watermark parameters, including font, color and transparency, automatic stroke, font size, rotation angle, display grid lines, fill method, tile density, and so on. As can be seen from the screenshot, the rotation angle (clockwise) is on, and the value is 30; the filling method is "tile"; the tiling density is "sparse".
These settings directly affect the visual effects after processing. When the rotation angle is 30, the text watermark will be displayed in an oblique form, which is more consistent with the common watermark style. When the filling method is set to tile, the watermark will appear repeatedly in multiple positions on the page instead of only one. When the tile density is sparse, the space between watermarks is large, which will not excessively block the body content. From the screenshots after processing, we can also see that there are many inclined "TEST" words on the page, which are eye-catching as a whole but can still read the text.
If your PDF content is dense, it is recommended to maintain a lower density; if the file is mainly used for strong identification and non-proliferation, the watermark can be appropriately improved. Since the screenshot does not show the specific expansion options of each switch, the actual operation should be based on the software interface display, and can be set as required.
Step 5: Set the save location and start processing
after setting the watermark parameters, click Next at the bottom of the page ". According to the flow at the top of the wizard, you will next enter "Set the save location" and then enter "Start processing". Although the screenshot does not show the specific saving options for subsequent pages, it is clear that the software uses a step-by-step wizard, and the user needs to first determine the location of the processed PDF to save, and then follow the interface to guide the execution of the process.
It is recommended to prepare a separate folder for the output file before batch processing, such as Watermarked PDF or Output File ". In this way, the processed file can be avoided from being mixed with the original file, and it is also convenient to compare the effect before and after processing. If it is an important contract, report or customer data, it is recommended to keep the original PDF backup to ensure that the watermark text, angle or density can be reprocessed later.
Frequently Asked Questions and Precautions
1. Why is it recommended to use a small amount of PDF to test the watermark effect
batch processing has the advantage of processing multiple files at once, but it also means that setting errors can affect multiple PDFs at the same time. Therefore, before formally processing a large number of files, you can select 1 to 2 PDF for testing to confirm that the watermark text, tilt angle, tile density will not affect reading, and then batch import all files for processing.
2. What is the difference between text watermark and picture watermark
as can be seen from the screenshot, PDF watermark function supports "text watermark" and "image watermark" two types. Text watermarks are suitable for adding text identifiers such as "TEST", "internal information" and "confidential". Picture watermarks are usually used in scenes such as company logos and seal patterns. This article demonstrates a text watermark, so you can select Text Watermark.
3. Batch add watermark after how to confirm the success
after the processing is completed, it is recommended to open several output PDFs at random for inspection. Focus on whether the watermark appears on the page, whether the text is correct, and whether the angle and density meet expectations. The post-processing effect in the screenshot shows that "TEST" has appeared on the PDF page in an oblique tile, which is a typical result of successfully adding a text watermark.
4. Why pay attention to the number of records in the file list.
after the file is imported, the number of records appears at the bottom of the list. The number of records in the screenshot is 4, indicating that 4 PDFs will be processed. If 20 files should actually be processed, but the number of records only shows 10, you need to check whether any files have not been imported. In batch office scenarios, checking the quantity before processing can effectively reduce the problem of missing processing.
Summary: Using batch processing tools to uniformly add text watermarks to PDF is more efficient
.Add text watermark to PDF in batch, which is essentially to hand over repeated document editing actions to office software for automatic completion. By HeSoft Doc Batch Tool The "PDF Add Watermark" function of the, you can import multiple PDF at once, set the text watermark content, rotation angle, tiling method and density in a unified way, and then press the wizard to set the save location and execute processing. Compared to manually adding watermarks by opening PDFs one by one, this method is more time-saving and easier to ensure consistent watermark styles.
If you often need to process contract PDF, report PDF, training PDF, review PDF or a large number of archived documents, it is recommended to hand over such batch watermarking tasks to specialized document batch processing software. The next time you encounter dozens of PDFs with "internal data", "TEST" or "for review only" watermarks, you can quickly get a unified and standardized output file by following the steps in this article.
