Resize Video
Change a video's resolution
About this tool
Change the resolution of a video to make it smaller and lighter. Pick a target height and the width is adjusted automatically to keep the original aspect ratio. Processing happens entirely in your browser.
Media processing uses a local engine in your browser. The first run may download the processing runtime once; afterward, conversions stay on your device so footage is not uploaded to DevToolDeck.
How to use it
- Select the video or audio file to process.
- Choose format, quality, or edit options for this tool.
- Start processing and wait for the local engine to finish.
- Download the output file to your device.
Common use cases
- Convert clips for editing or social uploads.
- Shrink large recordings before sharing.
- Trim intros/outros without a full NLE.
- Extract audio or mute tracks privately.
Frequently asked questions
Will the aspect ratio change?
No. You choose the height and the width is scaled to match, so the video keeps its original proportions.
Can I make a video larger?
You can, but upscaling a video to a higher resolution than the original won't add real detail. Resizing down is recommended.
Does Resize Video upload my files or text?
No. Processing is designed to run in your browser. Your inputs are not uploaded to DevToolDeck servers for conversion.
Do I need an account?
No. You can use the tool immediately without signing up.
Is the tool free?
Yes. DevToolDeck tools are free to use in the browser. The site may show ads to keep the service available.
