"Multi-threaded WebAssembly instances compile desktop-grade media libraries directly to machine instructions within the browser page. This allows client-side audio parsing and frame compression, ensuring heavy media assets do not require cloud transfer."
— Elena Rostova, Chief Systems Engineer, WebMedia Standards Working Group

Optimize Video Files Privately

Sending video attachments via email or discord is often blocked by file size limits. Our Compress Video utility makes it easy to shrink video weights using advanced client-side processing, preserving key frames and audio sync.

Why Choose TinyWeb?

Most online video converters upload files to remote servers, which takes a long time and compromises your privacy. TinyWeb uses browser capabilities to execute optimizations locally, delivering fast compression speeds without the security risks.

Intelligent Bitrate Adjustment

TinyWeb analyzes your video track resolution, audio channel, and frame rates to apply the best bitrate reductions, ensuring your compressed videos look sharp and play smoothly on all devices.
