This tool converts MPEG to WEBM completely free and without any functional limitations. Since it is based on the browser API, the processing speed is the fastest because all files are processed locally on your device and are not uploaded to our server.
Batch Convert MPEG to WEBM Online
With this convertor, you can easily convert multiple MPEG files to WEBM format directly in your browser — completely free. You can also customize the video resolution (width and height) during the conversion.
To access advanced settings, click the Options button in the top right corner. There, you can set the output size for your WEBM files.
Additional Settings:
Video Size: Set the width and height for the output WEBM file.
Encoding Speed:Controls how fast the video is encoded. Faster speeds may result in larger file sizes.
Video Bitrate:Set between 1–10,000 Kbps to control the video quality and file size.
Frame Rate:Defines the video’s FPS (frames per second). Higher frame rates produce larger files.
Audio Bitrate:Recommended range is 16–320 Kbps.
Cut Video: Trim the video using a start and end time in HH:MM:SS format.
For example, setting 00:00:05 to 00:00:08 will cut a 3-second clip from the video or animation.
Before converting, you can choose a folder on your device where the converted WEBM files will be saved. Each MPEG file will be automatically saved to your selected folder after it's successfully converted — no manual downloads needed.
Save All: Once all MPEG files are converted, click
Save All to instantly save all WEBM files to your selected folder.
About MPEG files
MPEG (Moving Picture Experts Group) is a family of digital video and audio compression standards, including MPEG-1, MPEG-2, and MPEG-4, used for streaming, DVDs, and digital broadcasts. Unlike MPG (a specific file extension for MPEG-1/2 videos), MPEG refers to the broader encoding technology itself, supporting multiple file formats like MP4, AVI, and MKV. It enables high-quality compression for efficient storage and playback, powering modern video streaming and broadcasting systems worldwide.
About WEBM files
WebM is an open, royalty-free video format designed for web use. It supports efficient VP9/AV1 video compression and Opus/Vorbis audio, offering high quality with small file sizes. Ideal for HTML5 streaming, WebM works seamlessly in browsers like Chrome and Firefox, making it a top choice for online videos and web apps.
