Merge PDF files freely, securely, and directly in your browser.

Are you looking for a way to quickly merge multiple PDF files into one? Do you need to compile a report from different documents, combine scanned copies of a passport and an application, or create a single portfolio? 24glo.com offers a unique solution that combines the convenience of online services with the security of offline software.

Our “Merge PDF” tool allows you to combine an unlimited number of documents in just seconds. The key feature is complete confidentiality. Unlike other websites, we do not require you to upload your files to cloud servers. The entire merging process happens exclusively on your device, inside your browser. This means your data never leaves your computer or smartphone.

Why merging PDFs on 24glo.com is the best choice

There are hundreds of websites on the internet for working with PDFs. However, most of them follow an outdated model: you upload a file to a third-party server → the server processes it → you download the result. This approach has several critical drawbacks: the risk of data leaks, dependence on internet speed, processing queues, and file size limits.

We took a different approach and used modern web technologies (WebAssembly and JavaScript) to bring the power of a professional editor directly into your browser. Here’s what that gives you:

1. Absolute security and privacy

This is our top priority. When you add files to our tool, they are not transmitted over the internet. Technically, your browser opens them locally, just like a regular desktop application (such as Adobe Reader or Word). Neither site administrators, hackers, nor third parties can access your documents. This makes our service an ideal choice for lawyers, accountants, and anyone working with contracts, financial reports, and personal data.

2. Works without the internet (Offline)

It may sound unbelievable for a website, but it’s true. You can load the 24glo.com page and then turn off Wi-Fi or switch to airplane mode. The tool will continue to work! You can merge gigabytes of documents on a train, plane, or in a location with poor connectivity. We call this “Local Online” — web accessibility with the reliability of desktop software.

3. No limitations

Forget messages like “Maximum file size 10 MB” or “Only 2 files for free.” Our service uses your device’s processor and memory, so we don’t impose artificial limits.

• Merge an unlimited number of files.
• Work with documents of any size (500 pages or even 5,000).
• Use the service as often as you need — no plans or subscriptions.

How to merge PDF files: step-by-step guide

We designed the interface to be as simple and intuitive as possible. You don’t need to be a computer expert to combine documents into a single file.

Step 1: Upload files

Click the upload area or simply drag and drop the required PDF files with your mouse (Drag & Drop). You can select dozens of documents at once. Our smart loader will instantly process them and display them as a list.

Step 2: Visual sorting and preview

After uploading, you will see cards for your files. For convenience, we generate a thumbnail of the first page of each document. This way, you won’t confuse “Contract_version_1.pdf” with “Contract_final.pdf” — you can immediately see what’s inside.

The order of files in the list determines the order of pages in the final document. Use the “Up” (↑) and “Down” (↓) arrows to arrange the files in the desired sequence. Forgot to add a file? Just drag it into the window. Added an extra one? Click the cross (✕) to remove it.

Step 3: Merge and download

When everything is ready, click the “Merge PDF files” button. The process takes a fraction of a second. The browser will create a new file called merged_document.pdf and automatically prompt you to save it to your device. Done!

Use cases: who is this service useful for?

PDF merging is in demand in many everyday and professional situations. Here are just a few examples of how 24glo.com makes life easier:

For students and teachers

Students often write academic papers in parts: the title page separately, chapters separately, references separately (because it’s easier to format that way). In the end, everything must be submitted as a single file. Our service lets you assemble a thesis or term paper in one minute without breaking the complex formatting of individual sections.

For business and document management

Office managers and secretaries regularly deal with scanning. Often, scanners save each page as a separate PDF. Sending a client an email with 20 attachments is unprofessional. It’s far better to merge all scans into one clean document. It’s also convenient for creating commercial proposals by adding a personalized offer and portfolio to a standard price list.

For freelancers and creative professionals

Designers, architects, and copywriters can collect their best work into a single portfolio (case study). You can easily combine landscape and portrait pages, diagrams, text, and images to create a presentable file for a client.

For personal use

Planning a trip? Combine airline tickets, hotel bookings, insurance documents, and copies of visas into one PDF file and save it on your phone. This way, all important documents are in one place, and you won’t have to search through different email folders at border control.

Frequently Asked Questions (FAQ)

Do I need to register or install software?

No! We value your time. The service works directly in the browser (Chrome, Safari, Firefox, Edge, Opera). You don’t need to register, leave your email, solve captchas, or download suspicious .exe files. Just open the site and get the job done.

Is quality lost during merging?

No. Our algorithm works carefully: it copies pages from the source files “as is” into a new container. Text remains vector-based (no blurring), images keep their original resolution, and links remain clickable.

Can I merge PDFs with different page sizes?

Yes, absolutely. You can merge an A4 document with an A3 drawing or a small receipt. The final file will contain pages of different sizes, and any PDF viewer will display them correctly.

Does the service work on mobile phones (Android / iOS)?

Yes. Modern mobile browsers fully support the technologies we use. You can merge documents directly on your smartphone or tablet, selecting files from device storage or connected cloud services (iCloud, Google Drive).
