About WebmConverter
Got a WEBM video that won't open? WebmConverter turns it into a file that plays where you need it.
Pick where it's going
You don't have to know which format to choose. Pick where the video is going, and WebmConverter sets the format and quality for you:
- Plays anywhere: MP4 for phones, TVs, browsers and editors
- Phone & WhatsApp: a smaller MP4 at up to 720p, quick to send
- PowerPoint & Office: MP4 that embeds in slides and documents
- Animated GIF: a silent loop for chats and web pages
- Just the sound: the soundtrack on its own, as MP3
- Keep everything: full size and high quality MKV, for VLC and media players
- Older players: AVI or WMV, for old software, DVD players and TVs
A whole batch at once
Drag in as many WEBM videos as you like, or add a whole folder. Click Convert once and they are all done. Each video shows its size before and after, and how much smaller it got.
Trim and preview
Click a video to watch it right in the app. Set a start and end time to keep just the part you want, or pause where you like and mark it from there.
Your settings, if you want them
Choose the size: the same as the original, 1080p, 720p, 480p, 360p, or your own width and height. Leave one blank and the video keeps its shape. Move the quality slider toward a smaller file or a better picture. Remove the sound with one switch. Make GIFs at 10, 15 or 24 frames per second, and save sound at 128 to 320 kbps.
Your files stay yours
New files are saved beside the originals, to a folder you pick, or in place of the originals, and you are asked first before anything is replaced. Everything is converted on your PC. Nothing is uploaded, and there is no account.
