Visual Separation and Deletion of PDF Pages Online and Offline

In modern digital document management, the PDF format (Portable Document Format) is the gold standard for information exchange. However, we often encounter situations where we don't need the entire massive report or book, but only a few specific pages. Or, conversely, it is necessary to remove confidential pages before sending a document to a client. It is for such tasks that the 24glo.com service has developed a unique tool: "Visual PDF Separation". This solution allows users to easily, quickly, and, most importantly, securely manage the contents of their PDF files both online and offline, directly in the browser.

What is Visual PDF Separation?

Traditional PDF splitting methods often require manually entering page numbers (e.g., "1-5, 8, 12-15"). This is inconvenient, prone to errors, and requires the user to constantly switch between the document viewer and the splitting tool. Visual separation changes the game.

On the 24glo.com platform, the process is built on clarity. By uploading a file, you see not just the document name, but a grid of thumbnails of all its pages. It works like laying out photos on a table: you immediately see the content of each page. This approach eliminates the possibility of error — you know exactly what you are deleting and what you are saving.

Key features of the tool:

• Interactive preview: Instant generation of high-quality page thumbnails.
• Selective saving: The ability to check only those pages that are needed in the new file.
• Quick deletion: Unchecking unnecessary pages automatically excludes them from the final document.
• Mass actions: "Select All" and "Uncheck All" buttons for working with large documents.
• Data security: Processing takes place on the client side (in the browser), without sending the file to the server.

Offline and Online Modes: Security First

One of the main features of the 24glo.com service is its hybrid approach to data processing. Unlike most online converters that require uploading your file to a remote server for processing, our tool uses browser technologies (JavaScript and WebAssembly) for local operation.

How does "Local Online" work?

When you visit the tool page, your browser downloads the necessary script. Once the script is loaded, you can disconnect from the internet — the tool will continue to work. When you select a file for splitting, it does not "fly away" to the cloud. All the magic of splitting and merging pages happens in the RAM of your computer or smartphone.

This provides three critical advantages:

1. Privacy: Your financial reports, legal contracts, personal passport scans, and other sensitive data never leave your device. Neither site administrators nor third parties have access to them.
2. Speed: You don't need to wait for a large file to upload to the server (upload) and download the result (download). Processing happens instantly, saving your time and internet traffic.
3. Independence: You can work with documents on the road, on a plane, or in places with unstable internet.

Use Cases: Who needs this?

The visual PDF separation tool from 24glo.com is a universal solution that finds application in a wide variety of fields.

1. For office workers and accountants

Often scanned documents are saved as one large PDF file. For example, a stack of invoices for a month or a multi-page contract with attachments. With visual separation, an accountant can "pull out" the necessary invoice to send to a counterparty or separate the main contract from confidential attachments in seconds.

2. For students and teachers

Educational materials are often distributed in the form of voluminous textbooks. A student may need only one chapter to prepare for a seminar. By uploading a textbook into the tool, you can select the necessary 20 pages out of 500 and save them into a separate, lightweight file that is convenient to read on a tablet or phone.

3. For lawyers and notaries

Legal privilege requires strict data protection. Using regular online services to split contracts is unacceptable. 24glo.com's offline processing technology allows lawyers to prepare extracts from documents, delete draft pages, or form document packages for court without violating security protocols.

4. For designers and architects

Portfolios and project documentation in PDF can weigh hundreds of megabytes. If you need to send the client only layout sketches, excluding technical drawings of communications, visual page selection is the ideal option. You see previews of the drawings and accurately select the necessary sheets.

Step-by-Step Guide: How to Delete or Save Pages

The interface of the service on 24glo.com is designed with a focus on minimalism and intuitiveness. You don't need to read long instructions to start using the tool. Here is a simple algorithm of actions:

Step 1: Upload File

Click on the upload area or drag and drop your PDF file into the browser window (Drag & Drop). The system will instantly begin analyzing the document structure. Files of all PDF versions are supported.

Step 2: Visual Selection

After uploading, a grid with images of all document pages will appear before you.
- To save a page: Make sure there is a checkmark under the page thumbnail (or the page is highlighted with color/border).
- To delete a page: Simply click on the page or checkbox to deselect it. The page will become faded or lose its selection border.

Use control buttons to speed up the process:
- "Uncheck All": Convenient if out of 100 pages you only need to save two. Deselect all, and then click only on the ones you need.
- "Select All": Useful if you need to delete only one or two pages. By default, all pages are selected, just uncheck the unnecessary ones.

Step 3: Generation and Download

When the selection is made, click the "Save Selected Pages" button. The service will assemble a new PDF file consisting exclusively of the sheets you marked, preserving their original quality and formatting. The file will automatically download to your device.

Technical Advantages of the 24glo.com Solution

Why choose our service among many analogs? The answer lies in the details of the technical implementation.

• High rendering quality: We use advanced libraries for rendering thumbnails. Even if your PDF contains complex drawings or small text, you will be able to distinguish the content in the preview thanks to adaptive scaling.
• Preservation of metadata and quality: When splitting a file, we do not re-compress the page content. Text remains text (and does not turn into an image), links remain clickable, and vector graphics retain clarity when printing.
• Cross-platform: The tool works in any modern browser (Chrome, Firefox, Safari, Edge) and on any operating system (Windows, macOS, Linux, Android, iOS). You do not need to install heavy programs like Adobe Acrobat.
• No limits: Many free versions of programs have limits on the number of pages or launches. We strive to provide maximum free access to basic editing functions.

Frequently Asked Questions (FAQ)

Will the quality of my document suffer during splitting?

No. The splitting process on 24glo.com works on the principle of object copying. We take pages from the source file and transfer them to a new container without rasterization or re-compression. Your text will remain vector and searchable.

Can I delete pages from a password-protected PDF?

To work with encrypted files, you will first need to enter the owner password so that the browser can decrypt the content for preview. If you have the right to view and edit, the service will handle the task.

How long does it take to process a large file?

Speed depends on the power of your device, as processing happens locally. On a modern computer, a file of 100 pages is processed and split in a few seconds. This is significantly faster than uploading a file to an online converter server.
