Is this video resizer really free?

Yes, completely free with no hidden costs, watermarks, or usage limits.

Do you upload my videos to your servers?

No. All processing happens in your browser using your device's CPU — your videos never leave your computer.

What's the maximum video size?

You can process videos up to about 500MB. Larger or longer videos take more time depending on your device.

Will resizing reduce video quality?

The tool uses high-quality encoding to preserve as much detail as possible. Choose the High quality setting for minimal loss.

Which output format should I use?

MP4 offers the best compatibility across devices and is the default. WebM produces smaller files; if your browser can't record MP4, WebM is used automatically.

What aspect ratio should I pick for each platform?

Use 9:16 vertical (1080x1920) for Reels, TikTok, Shorts, and Stories; 16:9 horizontal (1920x1080) for YouTube; and 1:1 square (1080x1080) for Instagram and Facebook feed posts.

Can I batch process multiple videos?

Currently you process one video at a time for the best performance and lowest memory use.
