London, United Kingdom – Jun 29, 2026— Softaken, a software company with over a decade of expertise in developing document management tools, has announced the launch of its browser-based Merge PDF utility for free as part of the Softaken Online Document Toolkit. With this tool you can merge multiple PDF files into one document, no account required, no software to install or files uploaded to third party server.
The distinctive feature of the tool is the location of the processing. Most online PDF utilities upload the files to a cloud infrastructure to process them on the server-side but Softaken's implementation is completely inside the user's web browser using JavaScript, more specifically, the open-source pdf-lib library. They never leave the machine. Files are read from the local device and written back to the local device.

How the tool works:
Users go to the Merge PDF page, drag two or more PDF files into the upload area, optionally reorder them and click Merge. The processing takes place locally and the combined document is available to download right away. No login, subscription or browser extension required for the whole workflow.
It runs on any recent Chrome, Firefox, Edge or Safari browser and is available for Windows, macOS, Linux, Chromebook and mobile. Since computation happens on-device there is no server queue or upload delay and very large files are limited only by the user’s machine’s available memory and not server-side file size limits.
The core processing functionality continues to work offline after the initial page load, which may be relevant for users working in bandwidth-limited environments, or with sensitive documents they prefer to keep entirely disconnected from the internet.

Privacy and Security Concerns
For those who deal with contracts, financial records, legal filings or confidential business documents, it is a meaningful question to ask where a file goes once it is processed online. Most popular online PDF services upload documents to third-party servers where the files can be stored for some time, even after processing is done.
Softaken’s approach is structurally browser-native, thus avoiding this issue. No network request with file data is made so it is not possible to intercept the transmission, store the files on the server or share the files accidentally. The company says users can confirm this behavior themselves by looking at the browser network activity during a merge operation.
