Neural per-frame super-resolution
Every frame is run through a convolutional network (Anime4K) on your GPU that reconstructs edges and detail as it doubles the resolution: a real AI video upscaler, not a blurry stretch.

Three steps
How it works
Upload a short clip
Drag in or choose a video (MP4, MOV, WebM). Keep it short: video upscaling in the browser is heavy. It stays on your computer.
Pick the content type & upscale
Choose Real footage, Anime or 3D so the right neural weights are used, then click Upscale. Every frame is enhanced on your GPU and the audio is carried over.
Preview & download
Watch the upscaled clip in the player, then download the 2× MP4, ready to upload or edit.
Built for creators
Why people choose it
Keeps your audio
The soundtrack is carried across into the upscaled MP4, so you get an enhanced video that still has its audio, not a silent clip.
Runs on your GPU, fully local
The upscaling happens on your own graphics card via WebGPU. Nothing is uploaded, so it works as a private video quality enhancer for personal and client footage.
Weights tuned per content
Real footage, anime/cartoon and 3D/game capture each get their own retrained weights, so the enhancer suits the kind of video you actually have.
No credits or watermark
Because it runs on your machine there is no per-clip charge and nothing stamped on your video, a genuinely free video enhancer.
Nothing to install
It is a web page, not an app. Open it, drop a clip in, and download the upscaled MP4, with no download and no extension.
How to upscale a video for free
When a clip looks soft or low-resolution, an AI video upscaler can rebuild it at a higher resolution frame by frame. This tool does it in your browser: drop in a short MP4, MOV or WebM, pick the content type, and it upscales the video 2× using a neural network running on your GPU, then hands you an MP4 with the audio kept. No upload, no account.
Because it reconstructs detail rather than just stretching pixels, enhancing video quality this way looks better than a plain resize. It is a fast, free way to improve video quality and increase resolution on a short clip: a real video quality enhancer, not a filter.
A free alternative to paid video enhancers
Desktop tools like Topaz Video AI are powerful but paid, and many online video enhancers upload your footage to a server and gate the free tier. This free video upscaler runs the whole 2× upscale on your own machine through WebGPU, so your video never leaves your device and there is nothing to pay or install. For personal clips and client work, that privacy is the point.
It is well suited to short clips where you want a quick AI video enhancer: social videos, game or 3D capture, and anime, with weights you can match to the content.
Honest about browser limits
Upscaling video in a browser is demanding: every frame is decoded, enhanced on the GPU and re-encoded. So this tool is tuned for short clips at 2× rather than hour-long 4K jobs, and that keeps it fast and within your device’s memory. It shines on clean sources; heavily compressed footage improves but won’t become studio-grade. If your browser doesn’t support WebGPU, the tool tells you instead of failing silently.
How it compares
A free, private alternative to Topaz and online enhancers
Paid tools like Topaz Video AI, and online enhancers that upload your clip to a server, cost money and take your footage off your machine. This runs 2× upscaling on your own GPU, locally, for free.

Questions
Frequently asked questions
How do I upscale a video for free?
Drop a short MP4, MOV or WebM onto the tool, pick the content type, and click Upscale 2×. Every frame is enhanced on your GPU in the browser and you download the result as an MP4, free, with no sign-up and nothing uploaded.
Is this a free alternative to Topaz Video AI?
For short clips, yes. It runs neural 2× upscaling on your own GPU in the browser, free, private and with no install, where Topaz is a paid desktop app. It is not as feature-deep as Topaz, but for a quick, private, free upscale it does the job.
Does the upscaled video keep its audio?
Yes. The soundtrack is carried across into the upscaled MP4, so you get an enhanced video with its audio intact, not a silent clip.
Is my video uploaded to a server?
No. The whole upscale runs on your own device through WebGPU. Nothing is uploaded and no account is needed, so it is safe for private footage.
How long a clip can I upscale?
Keep clips short: browser video upscaling is heavy, so the tool is tuned for short clips at 2×. Longer or very high-resolution videos are better done on a desktop app.
How much bigger does it make the video?
It upscales 2×, so a 640×360 clip becomes 1280×720, and 960×540 becomes 1920×1080. You download the result as an MP4.
Why does it say my browser isn’t supported?
The upscaler needs WebGPU, available in the latest Chrome and Edge on desktop. If you see the unsupported message, update or switch browsers and reload.
Can I upscale images or anime instead?
Yes, use the image upscaler for stills, or the anime upscaler for anime and illustration (image or video). This page is tuned for real video footage.
