Hi! It sounds like you're trying to merge MP3 files using iLovePDF, but when you drop the MP3 files into the browser, it just plays them instead of merging. Is that right?

Just to clarify, iLovePDF is designed primarily for working with PDF files—merging PDFs, compressing, converting, etc. Unfortunately, it doesn't support merging audio files like MP3s. That's why your browser is just playing the MP3s instead of merging them.

If you're looking to merge MP3s, you'd need a tool specifically for audio files—something like Audacity or an online MP3 merger service rather than iLovePDF.

Would you like me to help recommend some tools or guide you on how to merge MP3 files using appropriate software? Or is your goal to combine MP3s into a PDF file in some way? Let me know so I can assist you best!
