What are MP4 video tools?

MP4 video tools help convert, compress, trim, crop, resize, merge, split and optimize video files in the browser.

Are these tools free?

Yes. ILoveTools MP4 video tools are free online utilities.

Do videos upload to a server?

No. The tools use browser-side processing when the browser supports the required WebAssembly features.

Browser-side MP4 workflows

ILoveTools MP4 video pages follow the same static-site architecture as the existing PDF, image and JSON tool collections. Each page has focused metadata, canonical URLs, Open Graph tags, Twitter cards, FAQ schema, breadcrumb schema and related internal links.

Because this project has no server-side video processor, video work is handled in the browser with FFmpeg WebAssembly when supported. That preserves the existing privacy-first model: files stay on the user's device and are processed locally.
