    • File formats supported in Smartcat

    Understand the wide variety of file formats supported by Smartcat for translation, from Microsoft Office and Open Office formats to hypertext, desktop publishing, and localization files. Learn about the upload process, unsupported formats, and security measures for an efficient and secure translation workflow.

    Smartcat supports a wide variety of bilingual and monolingual files. It detects each file’s format automatically.

    Simply drag and drop your files or select them when creating a new translation task or project.
