AI video enhancement.
A clearer view of every frame.

Old memories. Small clips. Your next creative project. Give low-resolution footage a little more room to shine, right in your browser.

Real AI super-resolution

An ESPCN neural network reconstructs fine luminance detail. Choose 2×, 3× or 4× output, with native 3× inference at its core.

A studio inside your browser

No Python setup or desktop installation. Open the page and process supported media with local browser APIs.

Private from start to finish

Your videos, images and processed results stay on your device. There is no media upload and no account to create.

Preview before you commit

Try an example, inspect a frame and compare the original with the enhanced result before processing your entire clip.

A BIGGER CANVAS

Upscale 720p Video to 4K in Your Browser

Give landscape clips and everyday footage more room on a larger screen. Choose 3× output to take a 1280 × 720 source to 3840 × 2160, then compare a frame before you export. Your source quality and device still shape the result.

Improve Old Home Video Quality Without Uploading Your Memories

Revisit the little moments in your family archive. Enlarge a short clip, adjust exposure and contrast, and inspect the result alongside your original. Everything stays on your device. AI can make a larger frame, but it cannot guarantee noise removal or recover details the camera never captured.

  • Exposure and contrast controls for a balanced frame
  • Private local processing, with no account required

MORE ROOM FOR YOUR EDIT

Try an Anime Video Upscaler Online for Short Animation Clips

Bring a favorite animated scene into a larger edit. Try 2×, 3× or 4× output and inspect line art, textures and subtitles in the preview. The tool uses the same general-purpose AI model for all footage, so check your scene carefully before committing to a full export.

  • Compare line work and small details before export
  • General-purpose enhancement; no frame interpolation

STILLS WITH POSSIBILITIES

AI Image Upscaler for Photos, Thumbnails and Video Stills

Need a larger image for a layout, presentation or video thumbnail? Open a JPG, PNG or WebP, choose your output size and compare the result. Native 3× AI reconstruction powers the tool; 2× and 4× outputs are resized from that reconstruction. Download a watermark-free PNG or JPEG.

  • Choose 2×, 3× or 4× image dimensions
  • Inspect the original and result in one comparison

How to upscale a video with AI in 3 steps

A straightforward workflow, from your first frame to your final download.

01

Add your video or image

Drop a supported file into the tool, or try a sample. Your media is read locally and never uploaded.

02

Choose a scale. See the difference.

Select your output size, enhance a preview and compare the result with the original before processing the full clip.

03

Save your enhanced file

Let the AI process your media, then download the result. No watermark, no account, and no subscription.

THE TECHNOLOGY BEHIND THE DETAIL

Real AI video upscaling. Built for the web.

Open-source technology meets a simple, private workflow.

On-device neural inference

A locally hosted ONNX model runs through WebAssembly. The model loads only when you start enhancing.

Frame-by-frame enhancement

Each decoded frame goes through the same enhancement pipeline for a consistent output resolution.

2×, 3× and 4× output

Native 3× neural reconstruction, resized to your selected output scale. See your exact dimensions before export.

Modern video encoding

WebCodecs and Mediabunny package supported video into a downloadable file, with codec checks before processing.

No media on our servers

Files are read locally. You stay in control of the source and decide when to download or remove the result.

Clean, usable downloads

Export without a watermark. Image exports and supported video exports are yours to use in your next project.

A free video enhancer with less friction

More control over your footage. Fewer things standing in the way.

A FEW THINGS YOU MIGHT BE WONDERING

Free AI video enhancer: frequently asked questions

What it does, how it works, and what happens to your files.

What is Real Video Enhancer and how does AI video upscaling work?+

Real Video Enhancer is a free browser tool that uses an ESPCN neural network to reconstruct image detail. For video, the tool decodes frames, enhances them locally and encodes a new file. AI can estimate detail; it cannot recover every fact missing from the original.

Is this the official REAL Video Enhancer desktop application?+

No. realvideoenhancer.org is an independent browser project. It is not affiliated with the REAL Video Enhancer desktop application or realvideoenhancer.com. Our comparison pages explain when a desktop tool is a better choice.

Is the AI video upscaler free and without a watermark?+

Yes. This browser tool has no signup, payment or watermark. Your device and browser determine practical processing limits, so try a short clip first.

Are my videos or images uploaded to a server?+

No. Media is read and processed on your device. The browser downloads the website, neural model and runtime files, but your selected media and results are not sent to us.

Can I upscale a low-resolution video to 4K?+

A 3× output from 1280 × 720 is 3840 × 2160. This browser tool accepts clips up to 720p-equivalent pixels, 30 seconds and 100 MB. Larger video exports depend on the browser encoder and device memory. The 4K guide helps you plan dimensions; a desktop GPU tool is often more practical for long 4K projects.

Which video formats and browsers are supported?+

MP4 and WebM are the best starting points. Decoding and exporting depend on codecs available in your browser. A recent Chrome or Edge is recommended for the broadest WebCodecs support. Unsupported files show a clear error instead of a simulated result.

Will an AI video enhancer fix every blurry video?+

No. Super-resolution is useful for low-resolution footage and soft edges, but severe motion blur, heavy compression and missing texture remain challenging. Compare the preview at its actual size and keep your original file.

How long does browser AI video enhancement take?+

Time depends on frame count, input size and your device. Local neural inference may take much longer than the clip’s running time. Start with a short sample and keep the tab open while processing.
