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