how to convert bmp to jpeg or gif on mac please ?

You can use the Save As command in Preview to do this.

Launch the application Preview - it's in your Applications Folder.

Use it to open the pics in question - drag them to the Preview icon in the dock, or use the File -> Open command. File -> Open means the Open... command in the File Menu)

When they are open you can use the Save As command - that's in the File menu too - like on every other Mac application.

The application is called

Preview

which is why I said

Launch the application Preview - it's in your Applications Folder.

Of course, if you're Mac is using a different language, it will be called something else.

Try saving the .bmp to the desktop and double clicking on it - that should open it in Preview (or the French equivalent)

Then do a save as and select JPEG
