Browser-based processing
Supported tools run directly in your web browser using client-side technology.
PDFextreme is built around a simple idea: whenever possible, your PDF files should be processed directly in your browser, without unnecessary uploads.
Many online PDF tools require users to upload documents to a server before processing them. PDFextreme takes a different approach for supported tools. Whenever possible, your files are processed locally in your browser, which helps keep your documents on your own device.
Supported tools run directly in your web browser using client-side technology.
For local tools, your PDF files do not need to be sent to PDFextreme servers.
You select the file, process it in your browser and download the result on your device.
When you use a supported PDFextreme tool, your browser reads the selected file locally, performs the requested action and creates a new downloadable file. This process is designed to happen on your device instead of relying on a remote server.
Select the PDF tool you want to use, such as Merge PDF, Split PDF, PNG to PDF or Add Page Numbers to PDF.
Pick a document or image from your device. The file is read by your browser for local processing.
The tool performs the task in your browser whenever the feature supports local processing.
A new file is generated and downloaded directly to your device.
For supported local tools, PDFextreme does not need to receive, store or process your PDF files on a server. This helps reduce exposure and gives users a more private way to work with everyday documents.
PDFextreme is designed to process many common PDF tasks directly in the browser. Availability and performance may depend on your device, browser, file type and file size.

Browser-based processing is powerful, but it also has limits. Large files, complex PDFs, encrypted documents, high-resolution images or older mobile devices may affect performance. Some advanced features may require different technology in the future.
Because processing happens on your device, speed depends on your browser, memory and hardware.
Scanned files, encrypted documents, unusual page structures or very large images may not process as expected.
Large JPG or PNG files may use more memory during browser-based conversion.
If PDFextreme adds advanced tools that require server processing, those tools should clearly explain how files are handled.
For supported browser-based tools, PDFextreme is designed not to upload your files, not to save them to the WordPress media library and not to store them in the website database.
Even when using browser-based tools, it is always a good idea to handle sensitive files carefully.
