Free Conversion offers quality options: Maximum, High, Medium, and Low. At High or Maximum quality, the visual difference from the original is minimal. You can also keep the original video resolution to preserve the quality to the maximum.

The conversion speed depends on the file size, the chosen format, and your computer's power. Long or high-resolution videos naturally take more time. Closing other browser tabs and heavy applications can help speed up the process.

After loading the video in Free Conversion, select the "Crop Only" mode. Then, click the scissors icon next to the file to open the crop editor. Drag the markers to define the desired segment and save. Exporting in crop mode is almost instantaneous, as the video is not re-encoded.

Yes. Select the "Extract Audio" mode and Free Conversion will generate an MP3 file containing only the video's soundtrack. It's a practical way to extract audio from video without needing complex editing programs.

Free Conversion uses FFmpeg, one of the most reliable and widely used media processing engines in the world, compiled to run in the browser via WebAssembly (WASM). This allows your browser to run video conversion natively, without relying on external servers or installations.
