Before you start

Which files do these tools accept?

This category contains 5 available tools. Check the selected tool’s input list before starting; the tools have different capabilities. Listed extensions: GZ, GZIP, ZIP.

Does converting overwrite my file?

No. Coverton reads the selected file and creates a separate result. Existing source files are not overwritten. Check the downloaded file’s content, size and quality before replacing any copy yourself.

Large files, honest limits

There is no fixed upload-size cap. Browser memory, decoded image dimensions, available storage and the file structure determine what can be processed. Start with a smaller batch when a task needs too much memory.
