Private PDF Tools with Local Browser Processing
Use supported PDF tools that process selected file contents locally in your browser. Learn what local processing means, what still connects to the network, and how to check each tool.
How does FlamePDF handle files in its local PDF tools?
For supported local PDF workflows, the browser reads and processes file contents on your device instead of uploading them to a FlamePDF conversion server for that operation. The site still makes network requests for resources and may make optional advertising or analytics requests, so local processing does not mean zero network activity.
How local PDF processing works
For supported FlamePDF PDF workflows such as compression, merging, splitting, page organization, and form filling, the browser reads the selected file and performs the operation on your device instead of uploading its contents to a FlamePDF conversion server. The tool creates a separate output for you to download.
Local processing has limits
Local file processing does not mean the website is offline or leaves no traces. FlamePDF downloads page code, styles, workers, and other resources; hosting and security providers may receive standard request metadata. Some optional site features may make additional network requests. Browser memory, cache, and downloaded files are managed by your device.
Check the specific tool
Processing details vary by feature. Check the individual tool and the Security & Architecture page for current behavior. Keep the original and review the exported copy before sharing it.
