Is the full video upscale free?
Yes. You can process and download the full video without an account, credits or an added watermark. The browser downloads model files; your selected video stays on your device.

About the AI and privacy
WebSR 0.0.16 runs locally with pretrained Small or Medium networks. Animation weights originate in Anime4K; real-life and 3D weights were retrained by WebSR’s maintainer, Sam Bhattacharyya. The model enlarges frames 2×, then fits them within 1920 × 1080 (or portrait). Model files download from DojoClip, with a verified public-storage backup. Your video is never uploaded.
WebSR 0.0.16 · MITHow to upscale a video with AI
- Select your video. Check the original and proposed output dimensions before starting. This tool chooses the size; it does not offer a custom resolution field.
- Match the settings to your footage. Choose Real-life footage, Animation or 3D / game footage. Balanced quality uses the larger model; Faster processing uses the smaller one. The output dimensions stay the same.
- Choose whether to keep audio. Start Upscale full video and keep the tab open. You can cancel if needed.
- Review and download. Play the processed video, compare width, height and file size, then save it before leaving the page or changing settings.
What output size will I get?
| Source | Output |
|---|---|
| 640 × 360 | 1280 × 720 |
| 1280 × 720 | 1920 × 1080 |
| 720 × 1280 | 1080 × 1920 |
The source proportions are retained. A 360p clip reaches 720p in one pass because enlargement stops at 2×; it does not automatically become 1080p.
Judge the picture, not just the pixel count
Compare the original and result at a similar viewing size, both paused and playing. Look at hair, outlines and text, then watch movement. Keep the original if the enhanced version introduces distracting detail. Re-encoding can also change quality and increase file size.
Trim a short test clip before processing a long recording. To change the shape to vertical or square, use Social Media Resizer. For a smaller download, use Video Compressor. Browse all free tools for other edits.
Questions about AI video upscaling
Can I upscale 720p to 1080p or 4K?
1280 × 720 can become 1920 × 1080, including the equivalent portrait sizes. Enlargement is at most 2× per dimension, with a 1920-pixel long edge and 1080-pixel short edge. There is no 4K export. Sources already at the output limit cannot be enlarged here.
Can AI fix blur and recover lost detail?
It may improve edges and apparent detail, but cannot guarantee the original detail or repair severe blur. Review faces, small text and moving textures for artificial patterns or flicker.
What do I need to run AI upscaling?
Use a current browser with video decoding and encoding support, plus compatible WebGPU graphics for AI. Start with an SDR H.264 MP4; MOV and WebM depend on codecs. HDR is unsupported. If AI is unavailable, Standard resize may still work.
How does AI differ from Standard resize?
AI uses pretrained WebSR models to enhance each frame. Standard resize enlarges with ordinary interpolation and needs no AI model or WebGPU. Both use the same output-size limits and re-encode the video.
Are the sound and frame rate preserved?
You can keep the primary audio track or export silently. Original frame timing is preserved, including variable frame rate. No intermediate frames are generated. Output prefers MP4 and uses WebM when the available video/audio encoders require it.
How long can my video be?
There is no fixed input duration or file-size cap. Completion depends on decoding, graphics memory, storage and device speed. Try a short section first; a long clip can take substantial time or exceed available resources.
