Description

Convert images, documents, PDFs, audio, video, archives, and other files through CalcDuo APIs. CalcDuo File Converter provides a searchable catalog of verified file conversions in Chrome. - Convert images, documents, PDFs, audio, video, archives, e-books, fonts, and other supported formats. - Search source and target format pairs. - Configure quality, dimensions, codecs, bitrates, page ranges, and format-specific options. - Queue up to 10 selected files and receive one ZIP for multiple outputs. - Follow real upload, queue, conversion, validation, and download progress. - Cancel jobs or reconnect after reopening the popup. - Preview supported image, audio, video, and PDF outputs. - Keep favorite and recent conversion pairs locally on your device. - Open a selected file link from an explicit context-menu action in Chrome Side Panel. Only files you select are uploaded for conversion. Jobs and files normally expire after 30 minutes. Inputs and outputs are validated and scanned where supported. The extension does not send or store the full URL of the active page.
