VidCompress / Reduce file size
Shrink any video to a target size without losing the quality you notice. Pick a preset or a custom MB target and compress in your browser.
Or jump straight to a destination:
Reducing a video's file size means re-encoding it at a lower bitrate or resolution so the same footage takes up fewer megabytes. You might do it to fit an upload limit, free up storage, email a clip, or share it faster on a slow connection. The trick is cutting size without cutting quality you actually notice.
VidCompress handles this in your browser for files under 300 MB — nothing is uploaded. Pick how small you need it (a destination preset or a custom MB target) and the tool chooses the resolution and bitrate that keep the most detail within that budget.
Quick reference
Decide how small you need it
Use a preset (Email 25 MB, Discord 10 MB, WhatsApp 16 MB, Social 50 MB) or set a custom target. Only go as small as you actually need — a larger target keeps more quality.
Add your video
Drop in any common format: MP4, MOV, WebM, AVI, MKV, or WMV. Files under 300 MB process locally on your device.
Compress
VidCompress re-encodes the file to your target, keeping resolution as high as the size budget allows.
Download the smaller file
Save the result. It defaults to MP4 so it plays everywhere the original did.
How do I reduce the size of a video?
Re-encode it at a lower bitrate or resolution. Drop the video on this page, choose a target size, and VidCompress produces a smaller file automatically.
How can I make a video smaller without losing quality?
Set the target only as small as you need and keep the resolution where possible. Lowering bitrate first is usually invisible; dropping resolution is what makes a clip look soft, so avoid it unless the target is very tight.
What makes a video file so large?
Mostly bitrate (how much data per second) and resolution (4K vs 1080p), plus length and frame rate. Lowering bitrate is the most efficient way to shrink a file.
Do I need to install anything?
No. Compression runs in your browser; files under 300 MB never leave your device.
Is it free?
Yes. The free plan compresses up to 300 MB locally with no signup or watermark.
