Online Video Format Converter

Online Video Format Converter is a free, browser-based video processing tool that requires no software installation and no server uploads. All conversions are processed entirely on your local device, ensuring complete privacy and security for your video content.

Supported Video Formats

This tool supports mutual conversion between 14 mainstream video formats, including:

• Common formats: MP4, MOV, WebM, AVI, MKV
• Extended formats: FLV, WMV, TS, M4V, 3GP, OGV, F4V, MPEG
• Animation: GIF (extract animated GIFs from video clips)

Whether you need to convert a MOV file from your phone to the universally compatible MP4, or turn a video clip into an animated GIF for social sharing, this tool handles it effortlessly.

Core Features & Settings

Beyond basic format conversion, the tool offers rich customization options:

• Video Codec: Choose from H.264, H.265/HEVC, VP9, or keep the original codec
• Resolution: Select 4K (3840×2160), 1080p, 720p, 480p, 360p, or keep original

Frequently Asked Questions (FAQ)

Are my videos uploaded to a server?

No. This tool is powered by WebAssembly technology, running entirely in your browser. Your files are never sent to any server, keeping your content completely private.

What is the maximum supported file size?

There is no hard limit, but performance depends on your browser's available memory. Files under 2GB are recommended; very large files may cause memory issues.

How fast is the conversion?

Speed depends on your device's performance. Browser-based processing is generally slower than desktop software. H.265 encoding, being more complex, takes longer than H.264.

Are there limitations for GIF output?

GIF does not support audio; audio tracks are automatically removed during conversion. Keep frame rate below 15 fps and use a lower resolution to manage output file size.

What should I do if conversion fails?

Try reducing the number of files in a batch, or lower the quality and resolution settings and retry. If memory runs low, the tool will automatically restart its processing engine and attempt again.
