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 M2TS to AVI 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 M2TS files to high-quality AVI 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 M2TS to AVI 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 AVI Format

Definition of AVI

AVI, standing for Audio Video Interleave, is a multimedia container format introduced by Microsoft. It is known for synchronizing audio and video playback and is widely used for its simplicity and broad compatibility with various codecs. AVI files are versatile, supporting high-quality video and audio, but they can have larger file sizes compared to more compressed formats like M2TS.

Flexibility and High-Quality Content

AVI's compatibility with multiple codecs allows it to maintain high-quality video and audio, making it a popular choice for storing and playing video content, especially in Windows environments.

Use in Digital Media

AVI is commonly used in digital media for storing and playing video content, particularly where high-quality audio and video synchronization is essential. However, its larger file size can be a limitation for streaming or storage-constrained applications.

Introduction to M2TS Format

Definition of M2TS

M2TS, or MPEG-2 Transport Stream, is used primarily for high-definition video on Blu-ray discs and in AVCHD. This format is known for its high storage capacity and is extensively used in professional-grade video recording and playback, particularly in high-definition video applications such as Blu-ray and HD video cameras.

High-Quality Video and Audio

M2TS is utilized for its ability to handle advanced video and audio codecs, making it suitable for high-definition video productions and home entertainment systems, including Blu-ray playback.

Compatibility with Blu-ray and HD Equipment

As a standard format in the high-definition video industry, M2TS files are compatible with Blu-ray players and various HD video players and editing software.

What Happens When Converting M2TS to AVI

Conversion to a Versatile and Widely-Compatible Format

Converting from M2TS to AVI involves transforming high-definition video into a format that is more versatile and widely compatible. This process aims to retain the high quality of the original video while adapting it to the AVI format's capabilities, often leading to a more streamlined playback experience on a wide range of devices and media players.

Potential Increase in File Size

Since AVI is typically less compressed than M2TS, converting to AVI might result in an increase in file size. This should be considered if storage space or bandwidth for streaming is a concern.

Enhanced Usability Across Devices

By converting to AVI, the content becomes more compatible and adaptable for use on a broad range of devices and media players, extending its usability beyond specialized Blu-ray and HD video equipment.

Considerations When Converting M2TS to AVI

Evaluating Purpose and Compatibility

Before converting to AVI, consider the intended use of the video file. AVI is well-suited for many systems, but it may not be the best choice for applications that require a more compressed format.

Understanding Quality and Size Trade-offs

Be aware of potential changes in video quality and file size when converting from M2TS to AVI. The original quality of M2TS might not be fully retained in the AVI format, especially if the M2TS file contains high-definition or advanced audio codecs.

Selecting Appropriate Conversion Software

Choosing the right software for converting M2TS to AVI is crucial. Opt for a tool that can effectively handle the conversion process without compromising the integrity of the audio and video content.

Security in Conversion

For video files with sensitive content, choose a conversion service that ensures privacy and security. performs M2TS to AVI conversions directly on your local device, safeguarding the confidentiality and security of your files. This local conversion method prevents your data from being uploaded to external servers and provides protection throughout the conversion process.
