Frequently Asked Questions

Is this AI video upscaler free to use?

Yes — this video upscaler free service runs entirely in your browser with zero cost. No hidden charges, no credit card required, and no watermarks on your output. The AI model runs locally via WebGPU, so we don't incur server costs. If you choose cloud-based 4K enhancement, resource fees may apply and will be clearly indicated before processing.

Will there be a watermark on my video?

No. There is absolutely no watermark added to your upscaled video. What you see is what you get — a clean, enhanced video ready to use anywhere.

How does browser-based video upscaling work?

We use WebGPU to run an AI super-resolution model directly in your browser. Your video file is decoded locally, each frame is processed by the neural network on your device's GPU, and the enhanced frames are encoded into a new MP4 — all without any data leaving your computer.

Can this upscale video to 4K?

This video upscaler free performs 2x super-resolution in your browser. Due to device GPU and browser model constraints, local output is capped at 2K — completely free. If you need true 4K output, we offer cloud-based AI enhancement — because cloud models can run at a larger scale, this requires uploading your video to our servers and may incur resource fees.

What video formats are supported?

Currently supported input formats: MP4, MOV, WebM, and M4V. Output is always MP4 (H.264) for maximum compatibility across devices and platforms.

Is there a file size limit?

Since processing happens entirely on your device, there is no hard file size limit. However, larger files will take longer to process based on your device's GPU capability. For the best experience, we recommend videos under 500 MB.

Is this free video upscaler unlimited?

For local browser processing, there is no server-side daily quota and no watermark. The practical limits come from your own device: long videos, high resolutions, and weaker GPUs may take more time or run out of memory. For the smoothest free experience, process shorter clips first.

Are my videos safe? Do you store or upload them?

Your videos are completely safe. The entire processing pipeline — decoding, AI upscaling, and encoding — runs locally on your device. No video data is ever uploaded to any server, stored in the cloud, or accessible to anyone but you.

How long does video upscaling take?

Processing time depends on your device's GPU, video length, and resolution. A 30-second 1080p video typically takes 2–5 minutes on a modern GPU. WebGPU acceleration makes this significantly faster than traditional CPU-based upscaling.

Can it fix old or damaged videos?

Yes — the AI denoising and detail restoration are particularly effective on older footage. It can reduce grain, clean up compression artifacts, and restore lost details. However, severe physical damage (tape wrinkles, major color shifts) may need specialized restoration tools.

Do I need to install any software or browser plugins?

No installation needed. The upscaler works directly in Chrome, Edge, and other Chromium-based browsers that support WebGPU. Just open the page, drop your video, and start enhancing — no extensions, no downloads, no setup.

What makes this different from other online video upscalers?

Three key differences: 1) This video upscaler free is truly free with no watermarks — most 'free' upscalers add watermarks or limit you to 480p. 2) Local browser processing — your videos never leave your device, unlike cloud-based tools that upload your files. 3) No account required — start upscaling immediately without sign-up.
