Video Resolution Upscaler
Upscale local video frames to 1080p, 1440p, 4K, or up to 2× with high-quality browser interpolation.
About this tool
Create a higher-resolution copy of a local video using your browser’s high-quality frame interpolation. Choose a target size, set the output bitrate, and download the re-encoded result.
How to use this tool
- Choose a local video file
- Select a target output size and bitrate
- Choose an export codec supported by your browser, upscale, and download
How it works
The browser decodes each source frame, scales it onto a larger canvas with high-quality image smoothing, and records the canvas as a new video. Source audio is included when browser media capture exposes its audio track.
When to use this tool
- Creating a larger-resolution copy for an editing timeline
- Preparing smaller source footage for a 1080p or 4K canvas
- Standardizing local clips to a consistent output resolution
Frequently asked questions
Does this use AI to create missing detail?
No. It uses browser interpolation to enlarge frames. It cannot reconstruct detail that is absent from the original video.
Can I upscale a video to 4K?
Yes, the output target can reach 4K dimensions, subject to your device and browser encoder limits.
Is the video uploaded?
No. The source is decoded and the new video is encoded locally in your browser.
Limitations
This is resolution scaling, not AI enhancement or denoising. Processing runs in real time, output is capped at 4K, and codec/audio support and performance vary by browser and device.
Privacy
The selected video is processed in browser memory and is not uploaded.
