Choose the file format you have and the format you need. Open the matching converter, select your file, and download the converted result. Your files are processed on your device instead of being uploaded for conversion. Different formats have different strengths, so each tool includes helpful advice on compatibility and quality.
Some formats require a compatible browser or have limitations, especially for animation, advanced image features, and complex documents. Check the result before sharing it, and keep your original file in case you need to try another format.
