Browser video tool

AI Video Upscaler

WebGPUWebGL2x outputLocal processing

Enhance video quality with local AI super resolution. Files stay in the browser; no upload is required.

Source video
Choose a file
Drop a file here, or click to choose one.

Higher quality is slower and uses more GPU memory.

How it works

ArtPlayer loads AI super resolution model weights locally, sends frames to a browser worker, and exports a new MP4 result.

100% local
No server upload; the selected video stays on this device.
Private
Processing happens in browser APIs and local workers.
GPU ready
Uses WebGPU or WebGL where the browser supports it.
Free tool
No account, no watermark, no payment flow.

How it works

Three steps to finish the browser workflow.

  1. 1

    Choose a video file

    Enhance video quality with local AI super resolution. Files stay in the browser; no upload is required.

  2. 2

    Start upscaling

    ArtPlayer loads AI super resolution model weights locally, sends frames to a browser worker, and exports a new MP4 result.

  3. 3

    Download MP4

    Check the finished result, then download the exported file.

Frequently asked questions

Find quick answers about privacy, browser support, exports, and what to try when a file is heavy.

Are files uploaded for this tool?

This browser tool processes the selected media locally on this device. The file is not uploaded to ArtPlayer servers for this workflow.

Will the export have a watermark?

No. ArtPlayer browser tools do not add watermarks to exported files.

Why can processing take time?

The work runs in your browser, so speed depends on your device, browser, memory, source size, and the export settings needed for the result.

Which browsers work best?

Recent Chrome, Edge, and other modern Chromium browsers usually work best for heavier browser media processing.

What should I try if a large file fails?

Try a smaller source, close other heavy tabs, reduce resolution or duration first, and keep the tab open until the export finishes.

Does upscaling run in the browser?

Yes. The current upscaler loads the model locally and runs on your device when the browser supports it.

Why is upscaling slow?

AI upscaling is compute-heavy and depends on your browser, GPU support, memory, source resolution, and source length.

Can this improve low-resolution video?

Yes. The upscaler is designed to create a higher-resolution result from supported source video.

Will upscaling restore missing detail perfectly?

No. Upscaling can enhance perceived detail, but it cannot perfectly recover information that was never in the source.

What if the video is too large?

Try a shorter clip, a smaller source, or a desktop browser with stronger GPU support. Large files can exceed browser memory limits.
