Compress Video
Reduce video file size
About this tool
Make a video smaller by re-encoding it with the efficient H.264 codec. Choose how much to compress to balance file size and quality. Everything happens on your device, so your video is never uploaded.
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.

Frequently asked questions
Which level should I pick?
"Recommended" is a good balance. Choose "Strong" for the smallest file or "Light" to keep more quality.
Will the video lose quality?
Compression always trades some quality for size. The light level keeps more detail, while the strong level prioritizes a small file.
Does Compress 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.
