About JSM-Video.com

JSM-Video.com is a privacy-first collection of free browser-based converters for video, audio and images. Everything runs locally on your device using WebAssembly and HTML5 Canvas — your files never leave your computer.

What we do

We started because most online converters force you to upload private photos and videos to a server. That's risky, slow, and often costs money for large files. JSM-Video.com does the opposite: we compile tools like FFmpeg to WebAssembly (WASM) so MP4 to MP3, MOV to GIF, image resize, HEIC to JPG, WebP conversion and batch ZIP export all happen 100% offline in your browser tab.

Why local processing matters

Privacy: No server upload, no tracking of your media. EXIF GPS data is stripped automatically.
Speed: No waiting for uploads/downloads.
Free forever: No credits, no watermarks.
