How to convert video in multiple formats

Need to send a video via email, upload it to social media, or save it on your phone without taking up all the space? Online video conversion and compression saves you time and effort. Open your browser, choose the format, adjust the quality, and download in minutes.

Online services are quick and easy. They don’t require installation and work on PCs and smartphones. They generally offer broad format support, fast cloud conversions, and automatic file deletion. This guide provides a step-by-step procedure and practical tips for obtaining smaller files without losing quality.

Why convert and compress videos online: real benefits

Smaller files load faster, take up less space, and are easier to share. Conversion makes the video compatible with any device and platform. Compression reduces file size by adjusting bitrate, resolution, and codec.

In 2025, the most popular formats are MP4 with H.264 or HEVC H.265 codec for video and AAC for audio. Other common formats include MOV, AVI, MKV, GIF, and MP3. MP4 remains the safe choice for social media, email, and smartphones.

Online services are good for quick jobs with reasonable file sizes. For very large projects or complex edits, desktop software offers more local control. A reliable service like MediaConverter.Online offers over 1000 formats, no watermarks added, fast conversion, batch processing of up to 20 files, and privacy with automatic deletion after about 2 hours.

Conversion vs. Compression: What Really Makes a Difference

Conversion: Change container or codec for compatibility. For example, from AVI to MP4 to open the file on a TV or Android device.
Compression: Reduces the file size by choosing a lower bitrate, lower resolution, or a more efficient codec. For example, compress a 1080p file from 500 MB to 150 MB for chatting.

Most compatible formats in 2025

MP4 H.264: Safe option, compatible with almost all devices.
HEVC H.265: Smaller file size for the same quality, if the device supports it.
AAC or MP3: For audio only, AAC offers better efficiency at the same bitrate.
Social media prefers MP4.
MKV makes sense for Content with multiple audio tracks and subtitles.
MOV is ideal for the Apple ecosystem and for post-production.
AVI is only used for older systems or legacy streams.

When to use an online converter instead of a program

Online: Quick operations, small or medium files, moderate batch conversions, even 4K with the premium plan. Excellent when speed matters and you don’t want to install anything.
Desktop: long projects, heavy editing, local automation, sensitive materials that shouldn’t be uploaded online.

Choose based on time, file size, privacy requirements, and connection stability.
