VidCompress / Video compressor
Compress MP4, MOV, WebM, AVI, MKV, and WMV files to a target size directly in your browser. Nothing is uploaded for files under 300 MB.
Or jump straight to a destination:
A video compressor reduces the file size of a video while keeping it watchable. You might need one to fit an upload limit, attach a clip to an email, save storage, or speed up sharing on a slow connection. The catch with most online tools is that they upload your footage to a server first, which is slow and a privacy risk.
VidCompress compresses files under 300 MB directly in your browser using your own device's hardware. Nothing is uploaded, there is no queue, and there is no watermark on the free plan. Pick a destination preset — Email, Discord, WhatsApp, Telegram — or set a custom target size, and the tool handles the encoding settings for you.
Quick reference
Pick a target
Choose a destination preset (Email, Discord, WhatsApp, Telegram) or a size target. The preset sets the right resolution and bitrate automatically.
Add your video
Drag in an MP4, MOV, WebM, AVI, MKV, or WMV file. Files under 300 MB process locally; larger files use secure cloud mode.
Compress
VidCompress re-encodes the file to hit the target while preserving as much quality as the size allows.
Download
Save the smaller file. It defaults to MP4 for compatibility with every major platform and player.
What is the best free online video compressor?
The best one for you depends on privacy and speed. VidCompress compresses files under 300 MB locally in your browser with no upload, no queue, and no watermark — which makes it faster and more private than upload-first tools for everyday compression.
How do I compress a video without losing quality?
Set a target only as small as you actually need. The tool keeps the highest resolution that fits your target, so a generous target (like 50 MB) preserves more detail than a tight one (like 10 MB).
What video formats can I compress?
MP4, MOV, WebM, AVI, MKV, and WMV. The output defaults to MP4 for the widest compatibility.
Do I need to install software?
No. Everything runs in your browser. Files under 300 MB never leave your device.
Is there a file size limit?
Local in-browser compression handles files up to 300 MB. Larger files are supported through secure cloud mode.
