If you want to send an MP4 file, for example, via WhatsApp or email, it's easy to find that this isn't possible with large files. With file-converter-online.com, you can easily reduce the size of large MP4 files online. Of course, no watermark is added when reducing the file size.

How can I make MP4 files smaller?

Select your MP4 file from your PC (or Google Drive, DropBox) using the "Choose File" button
If necessary, change the preselection for the quality, but usually the preselection "optimal" will ensure good results
Optional: remove the sound from the video if it is not needed
Click on "Resize MP4" – the process will now start automatically.
Once your MP4 has been compressed, the download will start on the next page. You will then find the file in your download folder.
