Video tools
Free online video tools, process video without uploading
Browser-based video tools that handle common media tasks: reducing file size for social platforms and messaging apps, or extracting audio tracks as MP3. No file is ever sent to a server, all processing runs locally in your browser tab. No watermark is added to any output, no account is required, and everything works offline after the first visit.
Video processing that stays on your device
Most online video services require uploading files to remote servers, footage, recordings and personal content stored on infrastructure outside your control. Browser-based processing eliminates that exposure: every operation runs locally in your browser tab, files are loaded into memory, processed, and discarded when you close the page.
Compression and file size reduction
Reducing a video file size without installing software is one of the most common reasons people look for online tools. Social platforms each impose their own file size limits, messaging apps are particularly restrictive. Compressing a video locally in the browser means no footage leaves the device, which matters when the content is sensitive: a family video, a private conversation, or raw work footage. Choosing between a platform preset, a custom size target, or a quality-based setting gives full control over the trade-off between file size and visual quality.
Audio extraction from video
Separating the audio track from a video is a common media task: pulling a song from a music video, saving a lecture or interview as a standalone audio file, or creating a podcast episode from a recorded call. Doing this in a browser, with control over output quality and time range, removes the need for installed software or uploading sensitive footage to a third-party service.
Quality settings and output control
For compression, quality can be adjusted via a CRF value (constant rate factor) or by targeting a specific output file size. For audio extraction, bitrate determines how much audio data is preserved per second, lower bitrates suit voice recordings, higher bitrates preserve music fidelity. Time range extraction lets you process only the segment you need, which reduces both file size and processing time.
Privacy and offline use
All video processing runs in your browser. Nothing is transmitted, no account is needed and inputs are cleared when you close the tab. After the first visit, the processing engine (~30 MB) is saved locally on your device and all tools continue to work without an internet connection.
