Frequently Asked Questions

Is this tool completely free?

Yes, absolutely! There are no hidden costs, premium features, or subscription plans. Use it as much as you want, forever.

Are my videos private and secure?

Completely. Your videos are processed entirely on your device using WebAssembly technology. Nothing gets uploaded to our servers - we never even see your files.

Will resizing reduce my video quality?

We use high-quality scaling algorithms to maintain the best possible quality. While some quality changes are inevitable when scaling (especially upscaling), our tool minimizes quality loss.

How do I maintain aspect ratio?

The tool automatically maintains aspect ratio. When you set width, height is calculated automatically, and vice versa. Use the scale slider for proportional resizing.

What video formats are supported?

We currently support MP4, WebM, MOV, and MKV. If you have another format, try converting it first.

Can I upscale videos?

Yes! You can scale videos up to 200% or set larger dimensions. Keep in mind that upscaling will not add detail that was not in the original video.

Is there a file size limit?

The only limit is your device’s available memory. Since everything happens locally, larger files just take a bit more time to process.

Do I need to create an account?

Nope! Just visit the page and start resizing. No registration, no email required, no personal information collected.
