How to choose the right CASTARA tool

Start with the file you already have and the result you want to create.

Practical steps

Identify the current format from the file name or the application that created it. Then choose a tool whose title describes the action and output you need, such as Images to PDF or MP4 to MP3. Read the 'What to select' box before choosing files. Guest users can complete ordinary tasks without an account; when a task exceeds the displayed guest allowance, reduce the file count or size, or create a free account for higher limits. Review every result before downloading or sharing it.

Privacy and safety

Your selected files stay on your device. Keep backups, work only with files you are authorized to use, and verify every result.
