How browser-based file conversion protects privacy
Local processing keeps selected files on your device for supported tools, but normal website hosting and ads can still process page-level data.
What local processing means
For supported KlasseHand tools, the selected file is read by your browser and processed on your device. The converter does not need to upload the media file to a conversion server to produce the output.
What still leaves your browser
Like most websites, page requests, ads, hosting logs, and security systems can involve technical information such as IP address and browser details. The important difference is that the selected media file is not the payload being sent to a converter service.
Good habits
Close the page when you are done, keep your browser updated, and avoid converting files you do not have permission to process. For highly sensitive files, use a trusted offline workflow controlled by your organization.
