Online Video Compressor: Compress Video Size, No Upload

Compressing video online is simple with our tool: 1) Upload or drag & drop your video file, 2) Choose your desired output size or quality settings, 3) Click "Start Compression" and wait for the process to complete, 4) Download your compressed video. The entire process happens in your browser - no upload to servers required.

To compress video without losing noticeable quality: use our "Auto" mode which intelligently adjusts bitrate while preserving visual quality. For manual control, keep resolution at 1080p or original, use H.264 codec, and aim for a bitrate of 5-8 Mbps for high quality or 2-4 Mbps for good quality.

To reduce iPhone video size: 1) Open our website in Safari on your iPhone, 2) Tap "Choose File" and select your video from Photos, 3) Select a preset like "25MB Email" or "16MB WhatsApp", 4) Tap "Start Compression", 5) Save the compressed video to your Photos app.

No, there is no file size limit. You can compress videos of any size - 100MB, 1GB, 10GB or larger. Since all processing happens locally in your browser using your device's hardware, the only limit is your device's available memory.

No downloads or installations required. Our video compressor runs entirely in your web browser. Just open the website and start compressing - it works on any device with a modern browser (Chrome, Safari, Firefox, Edge).

The best free video compressor should offer: no file size limits, no watermarks, privacy protection, and high-quality output. Our tool checks all these boxes - plus it processes everything locally in your browser for maximum privacy.

Yes, 100% safe and private. Unlike most online video compressors that upload your files to remote servers, our tool processes videos entirely in your browser. Your video never leaves your device - we cannot see, access, or store your files because nothing is ever uploaded to our servers. This is the most private way to compress videos online.

We support all major video formats including MP4, WebM, MOV, MKV, AVI, WMV, FLV, and more. The output is always optimized MP4 with H.264 codec for maximum compatibility.

Compression time depends on video length, resolution, and your device's capabilities. With GPU acceleration enabled, a 5-minute 1080p video typically compresses in 30-60 seconds. Longer videos or older devices may take more time.

Yes! We have built-in presets specifically for Discord: 8MB for Discord Legacy, 10MB for Discord Free, 25MB for Discord Nitro Basic, 50MB for Discord Nitro, and 100MB for large file sharing.

If your compressed video is still too large, try: 1) Selecting a smaller target size preset, 2) Reducing resolution (1080p → 720p), 3) Lowering the quality/bitrate setting, 4) Trimming unnecessary parts of the video before compression.
