Offline Converter
Convert image, video, audio and document files offline by JavaScript in your web browser without any software downloads or file uploads! Offline converter is the opposite of online converter, it's for maximum protection of your privacy because all files are converted locally instead of cloud servers. Another advantage of offline converter is that file size can be up to 2 GB while very few online converters support file size larger than 100 MB.
Please note some web browsers do not support or do not fully support offline converter yet. We recommend using the latest Chrome browser for Windows. Try online converter instead if this offline converter doesn't work in your web browser.
