Free and unlimited use:

Enjoy free and unlimited MP4 to WEBM conversions with our service. Use it anytime, anywhere, for as many conversions as you need, without any restrictions.

Fully Local Conversion:

We deeply understand the importance of video privacy. Hence, we offer a fully local conversion service, eliminating the need to upload your videos to our servers. Experience enhanced security and privacy while converting MP4 to WEBM directly on your device. Our specialized local conversion process ensures your videos are never uploaded to our servers, guaranteeing complete confidentiality. This feature is especially ideal for handling sensitive or personal files, as it ensures your data remains exclusively in your hands. Convert your videos with confidence and peace of mind, anytime.

Balancing Size and Quality:

In the realm of video conversion, one of the key challenges is finding the perfect balance between file size and video quality. This balance is crucial because it directly affects both the usability of the file (in terms of storage and sharing) and the viewing experience. A high-quality video might be ideal for professional presentations or broadcasting, but it can be too large for quick sharing or limited storage scenarios. Conversely, a smaller file is easier to share and store but might lack the clarity and detail needed for certain uses.

Customization Based on Usage:

Customize your MP4 to WEBM conversions based on different use cases. For instance, a video intended for social media might prioritize a smaller size for easy uploading and streaming, while a film project might require the highest resolution and bitrate to ensure cinematic quality. This is where the ability to adjust various parameters like aspect ratio, resolution, frame rate, and bitrates becomes invaluable.

Instant File Size Preview Feature:

Recognizing these diverse needs, our service offers the "Instant File Size Preview" feature. As you adjust key parameters such as the aspect ratio, resolution, frame rate, video bitrate, and audio bitrate, our tool provides an immediate estimation of the resulting file size. This instant feedback allows you to make informed decisions on the spot, helping you to optimize your video for its intended purpose without the need for trial and error.

Fast conversion:

Understanding the importance of your time, our service is engineered for speed. We ensure quick and efficient conversion of your MP4 files to high-quality WEBM format, significantly reducing waiting times. With our advanced technology, experience the convenience of rapid conversions, allowing you to receive your converted files in a fraction of the usual time. is accessible on any device with an internet connection. Whether on a desktop, tablet, or smartphone, you can easily convert MP4 to WEBM anytime, anywhere.

Privacy Protection:

Your privacy is our priority. Your files are never stored on our servers, ensuring the security and confidentiality of your data.

Video parameters

Aspect Ratio:

Aspect Ratio refers to the width-to-height ratio of a video frame. Common aspect ratios include 16:9 (widescreen), 4:3 (standard), and 9:16. Choosing the right aspect ratio is crucial for ensuring your video displays correctly on various screens and fits the intended viewing experience.


Resolution determines the clarity and detail of a video. It is defined by the number of pixels along the width and height of a video frame. Higher resolutions (like 1080p, 2k, 4K) provide sharper and more detailed images, but also result in larger file sizes.

Frame Rate:

Frame Rate, measured in frames per second (fps), indicates how many individual frames or images are displayed each second in a video. Common frame rates include 24fps (cinematic), 30fps (standard), and 60fps (smooth motion). Higher frame rates result in smoother video playback but can increase the file size.

Video Bitrate:

Video Bitrate measures how much data is processed in a video stream per unit of time, usually in kilobits or megabits per second (kbps or Mbps). A higher bitrate allows for higher video quality and detail, but also increases the file size. Adjusting the bitrate can balance video quality with file size.

Audio Bitrate:

Audio Bitrate similarly measures the amount of audio data processed per second. Higher audio bitrates typically result in better sound quality but also larger audio file sizes. Adjusting the audio bitrate can optimize sound quality while managing overall file size.

Introduction to WEBM Format

Definition of WEBM

WEBM is an open, royalty-free, media file format designed for the web. It provides high-quality video streaming and is widely supported across various web browsers and platforms. Known for its efficient compression, WEBM is an ideal format for online video content, offering excellent video quality at lower bitrates, making it a preferred choice for web-based applications.
