Introduction

The Video Format Converter is an all-in-one tool that supports inter-conversion between MP4, AVI, MPG, MOV, FLV, 3GP, Web M, MKV, WMV, GIF formats. Unlike other video conversion tools, you can freely select the output format without switching pages. All conversion is done locally in the browser via FFmpeg.wasm, with no file uploads to the server, ensuring privacy.

Use Cases

FAQ

Q: Are files uploaded to the server during conversion?

A: No. This tool uses FFmpeg.wasm to run ffmpeg locally in the browser. All file processing happens in the browser with no uploads.

Q: Why is there a loading wait on first use?

A: The first use requires downloading the FFmpeg.wasm engine (~30MB). Once loaded, subsequent conversions don't need to re-download.

Q: Will conversion reduce quality?

A: Default CRF 23 (H.264) maintains high quality. Higher bitrate or lower CRF improves quality.

Q: Can I skip re-encoding?

A: Yes, select "Copy" as the video codec to remux only (fastest, lossless).

Q: What output formats are supported?

A: Supports 10 formats: MP4, Web M, MOV, AVI, FLV, 3GP, WMV, MPG, MKV, GIF.
