Shrink videos before uploading to social media. Faster uploads, less data usage, and your content stays sharp. Instagram preset optimizes for 1080px.
Most email providers limit attachments to 25 MB. Compress meeting recordings, presentations, and personal videos to fit email size limits. Email preset creates the smallest file.
Compress lecture recordings, screen captures, and project videos for submission. Fit videos into LMS upload limits. No software to install on school computers.

Yes, 100% free. No account, no subscription, no watermarks, no hidden fees. All compression happens locally in your browser. There is nothing to pay for.
No. BrowserCrunch uses the Canvas API and MediaRecorder built into your browser. Your video files never leave your device. No data is transmitted to any server. This is the most private video compressor available online.
MP4, MOV, AVI, MKV, WebM, and any video format your browser can play. Output is WebM or MP4 depending on your browser's capabilities.
Upload your video, select the WhatsApp preset, and click compress. The preset automatically caps resolution at 640px and reduces bitrate to create a small file that fits WhatsApp's 16 MB limit for video messages.
Upload your video, select the Email preset, and compress. The preset reduces resolution to 480px with aggressive bitrate reduction to create the smallest possible file for email attachments under 25 MB.
Set the quality slider to "Best quality" for minimal visual difference. Some quality reduction is inherent in compression, but at high settings the difference is barely noticeable. The trade-off is a larger output file.
Compression runs in real-time — a 1-minute video takes about 1 minute to process. Speed depends on your device since all processing happens locally. Desktop browsers are fastest.
No hard limit. Videos up to 500 MB work well on most devices. Larger files may take longer since processing is local. For very large videos, a desktop device is recommended.
Yes. The compressor works on iOS Safari, Chrome for Android, and all modern mobile browsers. The interface is touch-friendly. Large videos may process slower on mobile devices compared to desktop.
BrowserCrunch plays your video internally, draws each frame onto a Canvas element at a reduced resolution, and re-encodes the result with the MediaRecorder API at a lower bitrate. This produces a genuinely smaller file — not just stripped metadata.
Need to send a video via WhatsApp but the file is too large? Want to upload to Instagram faster? Need to fit a video into an email attachment? BrowserCrunch compresses your videos for free, right in your browser. No software to install, no files uploaded to the cloud, no account needed.
Most online video compressors upload your video to a remote server, process it there, and send it back. That takes time, uses bandwidth, and means your private videos travel across the internet. BrowserCrunch is different: everything happens locally in your browser. Your video never leaves your device. The result is faster processing, total privacy, and zero upload wait time.
WhatsApp limits video messages to 16 MB. A single minute of phone video can easily be 50-100 MB. Our WhatsApp preset automatically reduces resolution to 640px and lowers the bitrate to produce a compact file that fits the limit. Just upload, select WhatsApp, and compress. Your video stays sharp enough for mobile viewing while fitting within the size limit.
Smaller video files upload faster to Instagram and use less mobile data. Our Instagram preset caps resolution at 1080px — the maximum Instagram displays — and reduces bitrate for efficient compression. The visual quality stays excellent on phone screens while the file size drops significantly.
Gmail, Outlook, and most email providers limit attachments to 25 MB. Meeting recordings, event videos, and personal clips often exceed this. Our Email preset creates the smallest possible file by reducing resolution to 480px with aggressive bitrate reduction. Small enough for email, still watchable.
BrowserCrunch plays your video internally, draws each frame onto an HTML5 Canvas element at a reduced resolution, and captures the output with the browser's MediaRecorder API at a controlled bitrate. This is real re-encoding — not a fake "optimizer" that just strips metadata. The result is a genuinely smaller file with adjustable quality.
Three quality levels give you control over the size-quality trade-off. "Smallest file" reduces resolution to 40% and uses a low bitrate — ideal for WhatsApp and email. "Balanced" uses 60% resolution with moderate bitrate — good for most purposes. "Best quality" keeps 80% resolution with higher bitrate — minimal visual difference from the original.
Videos contain sensitive content — family moments, business meetings, personal messages, medical consultations. Unlike every other online video compressor, BrowserCrunch never uploads your video anywhere. All processing happens locally using the browser's built-in Canvas API and MediaRecorder. Your video data stays on your device, period. No server, no cloud, no third-party access.
