Free online AI video upscaler for clearer, larger videos
Give your footage a larger canvas. Choose a video, adjust its resolution and appearance, and export a new version directly from your browser—without uploading your footage.

Make low-resolution clips clearer with AI super resolution.
MP4, WebM, MOV · up to 100 MB, 720p & 30 secondsHow to upscale a low-resolution video online
Choose a compatible source up to 30 seconds, 100 MB, and the pixel count of 1280 × 720. Select 2×, 3×, or 4× output, then generate a first-frame AI preview. Compare that still before processing the complete clip. A modest increase is often more useful than an extreme enlargement.
- Use a 720p-or-smaller source; 1080p input exceeds this tool’s current limit.
- Keep the original aspect ratio to avoid stretching faces or objects.
- Compare fine edges and dark areas before choosing the final output scale.
A private video upscaler with practical export controls
Your selected video stays in the browser. Preview and export use your own device, so there is no upload queue or account to create. Browser codec support and available memory determine which files can be processed successfully.
Understand native 3× AI video upscaling and output scales
Every enhancement uses a compact ESPCN model on individual frames. The model predicts native 3× detail; 2× and 4× outputs are resampled from that prediction. Output is limited to the pixel count of 3840 × 2160, so some input-and-scale combinations are unavailable. This is per-frame super-resolution, without temporal restoration or frame interpolation.
Common questions about this workflow
How do I upscale a video without uploading it?
Open the video workspace and choose a compatible clip up to 30 seconds, 100 MB, and 921,600 source pixels—the pixel count of 1280 × 720. Select a scale and generate a first-frame AI preview before enhancing the full video. Processing stays local; keep the tab open and download the finished result.
Is Real Video Enhancer free to use?
The browser tools are available without a subscription, account, or added watermark. Videos are limited to 30 seconds, 100 MB, and 921,600 source pixels; images to 25 MB and 2.5 megapixels. Video output is capped at 8,294,400 pixels and image output at 16 megapixels, with a maximum 8192-pixel edge. Browser codec support and available memory also matter.
Can AI turn every low-resolution video into perfect 4K?
No. A larger output has more pixels, but missing original detail cannot be recovered with certainty. AI may infer plausible texture. Always check faces, text, fine patterns, and movement against the original. This tool accepts video up to the pixel count of 720p; a 1280 × 720 source at 3× produces 3840 × 2160 output when your browser can encode it.
What is the difference between the video and image tools?
Both workspaces use on-device ESPCN AI super-resolution. The model predicts a native 3× image; 2× and 4× outputs are resampled from that prediction. Video AI processes frames individually and does not create intermediate frames. Images export as stills, while video export encodes the processed sequence into a new file.
