Trim and cut videos precisely with frame-by-frame scrubbing. Set start/end points visually, preview clips in real-time, and export trimmed videos instantly. No upload required - runs 100% in browser.
Convert videos between MP4, WebM, OGG, MOV, AVI, and MKV formats. Device presets for YouTube, Instagram, TikTok, iPhone, Android. Quality options from fast to high quality encoding.
Merge multiple video clips into one seamless video. Drag-and-drop reordering, preview before export, timeline visualization. Combine videos in any format with automatic re-encoding.
Large video files are a problem when you need to email them, upload them to a platform with size limits, or simply save storage space. The Video Compressor reduces file size while giving you direct control over the quality tradeoff. Choose a target file size or quality level, and the tool calculates the right bitrate automatically. A real-time preview lets you check the visual quality before committing to the export.
Compress videos to fit within email size limits (typically 25 MB) while keeping them watchable.
Reduce file size to meet platform upload limits or speed up the upload process on slow connections.
Shrink large camera recordings to free up space on phones, tablets, or external drives.
Create lightweight video files that load quickly on web pages without buffering.
Compress video archives to reduce cloud storage costs while maintaining acceptable playback quality.
Video compression works by reducing the bitrate — the amount of data used per second of video. The compressor offers two approaches: target-size mode, where you specify the desired output size and the tool calculates the necessary bitrate, and quality mode, where you choose a quality level and the resulting file size varies. Two-pass encoding is available for target-size mode, analyzing the video first to distribute bits more efficiently across complex and simple scenes. The tool also provides resolution downscaling as an additional lever for size reduction when bitrate reduction alone isn't enough.
It depends on the source. A loosely compressed camera file can often be reduced to 20-30% of its original size with minimal visible quality loss. Already-compressed web videos have less room for further reduction.
Target size mode guarantees the output file won't exceed your specified size. Quality mode lets you set a visual quality level, with the resulting file size depending on the video's content complexity.
No. Audio is preserved and optionally recompressed at a lower bitrate. You can also choose to strip audio entirely if you only need the video track.
