VideoSlimmer - Smart Video Compressor

VideoSlimmer is a private online video compressor that reduces video file sizes directly in your browser, so your videos never need to be uploaded to a remote server. Whether you are trying to free up storage space or share clips that are too large to send, VideoSlimmer keeps the entire process on your own device.

Because the source file stays on your device, you get privacy by default. At the same time, you can compress videos, trim unwanted sections, resize the frame, fine-tune the bitrate, and adjust frame rates to export smaller videos that are easier to share and store.

Beyond the web-based tool, VideoSlimmer also offers native desktop and mobile applications for iOS, Mac, and Windows. These native apps are built to handle larger files and offline compression workflows, giving you more flexibility when a browser is not the right fit.
