What file types are allowed?

April 29, 2026

The upload chooser and the current Bmmplay feature decide which file types and sizes are accepted.

What to do

  • Use common web formats: JPG/PNG for images, MP3 for audio, and MP4 for video when practical.
  • Choose the correct upload control for that media type.
  • Read the message shown beside the field or after a rejected upload.
  • Do not rename an unsupported file extension to disguise its real type.
  • Ask support with the original filename, extension, file size, and upload page when the form does not explain the rejection.
