CalcDuo File Converter by Epik Bilgi Teknolojileri

Use a searchable catalog of verified server-side file conversions with format-specific options and real progress.

• Convert supported images, documents, audio, video, archives, e-books, fonts, and vectors.
• Search source and target formats and configure format-specific options.
• Queue up to 10 selected files and receive a ZIP for multiple outputs.
• Preview supported outputs and follow real conversion progress.
• Keep favorite and recent conversion pairs locally on your device.
• Open the workflow from the toolbar, an explicit context-menu action, or the Firefox sidebar.

Files are transmitted only after a deliberate user command and only to produce the requested conversion. The full URL of the active page is not transmitted or stored. Uploaded files and generated outputs normally expire after 30 minutes; exceptional remnants are removed within 24 hours.
