The file upload duration depends on your browser, file size and internet connection speed. Large files can take some time to upload. If you ever experience problems with uploading files and have an urgent need to convert a file, please try the following:

- Change your browser.

- Install our desktop app, which is especially convenient for the conversion of large files. It uploads and downloads files without having to use a browser, leaving you to browse the web freely while your files are converting.

- Contact support with details about your browser, and the file that won’t upload.
