Q: Why is this actually free when other tools have limits?
A: 100% client-side processing using WebGPU. Your device does the work, so we have zero server costs. We can afford to let you upscale billions of hours because it costs us $0. Other tools pay for server processing, so they need limits or subscriptions.
Q: How is this different from Canva's free video upscaler?
A: Canva requires signup, has 1 minute video limit, and max 1080p resolution. We have no signup, no time limits, and support up to 4K.
Q: How is this different from TopazLabs?
A: TopazLabs primarily has desktop upscaling software, targetted at professional video editors willing to pay the license fee (several hundred USD). TopazLabs
will have better quality and is better for very blurry/low quality inputs, but it is also expensive and requires a dedicated NVIDIA GPU with cuda configured, and takes time to set up. TopazLabs also offers an online video enhancer with limits similar to Canva.
TopazLabs is best for professional videographers and editors, who likely would also be using professional editing software like Adobe Premeire Pro or Davinci Resolve.
Free.upscer.video is best for casual users, especially marketers and content creators using ai-generated video content that just want better quality than was free or low-cost tools provide.
Q: How is this different from Hitpaw?
A: Hitpaw's free version has a 10 minute limit, adds watermarks, and requires downloading/installing software and configuring GPU drivers. We have no time limits, no watermarks ever, and work instantly in browser.
Q: How is this different from Waifu2x or Video2X?
A: Those require technical setup, command line knowledge, and GPU driver configuration. We work instantly in any modern browser with zero setup.
Q: Is this really free?
A: Yes, completely free. No trial period, no credit card required, no hidden fees. Process unlimited videos forever.
Q: Are there any time limits?
A: No time limits on video length or processing time. Unlike Canva (1 min max), you can upscale a 10-hour video or even longer if you want.
Q: Are there file size limits?
A: No file size limits, but very large files may be slow to process depending on your device.
Q: Do you add watermarks?
A: No watermarks ever. Your output is completely clean. Unlike Hitpaw's free version which adds watermarks, ours are always watermark-free.
Q: What's the maximum resolution?
A: You can upscale up to 4K, which is a limit set by Browsers and codecs for encoding the output video. Upscaling images typically allows outputs up to 8K, depends on the limitations of your device. Canva's free tier only goes up to 1080p.
Q: Will this stay free forever?
A: Yes. The free version will always be free.
Q: How does it work?
A: We use WebGPU (or WebGL as fallback) to process videos directly in your browser using your device's graphics card. No uploads to servers required. Learn more →
Q: Do you upload my videos?
A: No. Everything processes locally on your device. Your videos never leave your computer.
Q: What browsers are supported?
A: Chrome 94+, Edge 94+, Opera 80+, Safari 16+, and Firefox 130+ are supported (requires WebCodecs API). Chrome/Edge recommended for best performance with WebGPU. This tool automatically uses WebGL fallback (same quality, 50% slower) for browsers without WebGPU. Learn more about WebGL vs WebGPU →
Q: Does it work on Firefox?
A: Yes! Firefox 130+ is fully supported using WebGL fallback. Quality is identical to WebGPU, processing is just 50% slower. You can optionally enable experimental WebGPU support for faster processing.
Q: Does it work on mobile?
A: Yes.
Q: Do I need an account?
A: No account needed. Just visit the site and start upscaling. Unlike other tools which require signup such as Canva or Topaz, this tool has no log in, just use it.
Q: What video formats are supported?
A: MP4 format only (support for other formats coming soon)
Q: Can I upscale multiple videos at once?
A: Not simultaneously, but you can process as many videos as you want one after another.
Q: How long does processing take?
A: Depends on your hardware and video length. Typical: 1-2 minutes per minute of source video. A 10-minute video takes 10-20 minutes.
Q: Why is it slow?
A: Processing happens on your device, not our servers. Trade-off: completely free but slower. For short videos, like many AI -generated videos that are under 30 seconds, it is almost certainly faster to use this tool than it would be to use tools which require uploads. For longer videos, server-side processing is faster and has better results - see our paid version, which is much faster than free.upscaler.video, and much cheaper than other tools like TopazLabs or Tensorpix.
Q: How good is the quality?
A: Good quality using efficient AI models. For maximum quality, see our paid version which uses larger, more sophisticated models.
Q: Can I improve processing speed?
A: Close other browser tabs/apps, ensure latest browser version, or use our paid version for faster processing.
Q: What's the difference between free and paid?
A:
Free: Client-side processing, slower, good quality, unlimited use, $0
Paid: Server-side processing, much faster (minutes not hours), best quality, $5/hour of video
Q: When should I use the free version?
A: If you have short ai-generated video clips (under 1 minute), it is almost certainly faster to use free.upscaler.video than any server-based tool (TensorPix, Canva, Topaz, even our paid version)
Q: When should I use the paid version?
A: If you have longer video clips (longer than 5 minutes), or you need maximum quality, the paid verson is likely better. Learn more →
Q: Can I try both?
A: Yes!
Q: How does this compare to Topaz Video AI?
A: Topaz costs $299, requires installation and GPU setup. We're $0, work in browser, no installation needed. See detailed comparison →
Q: How does this compare to TensorPix?
A: TensorPix charges ~$30/hour. We're completely free with unlimited usage.
Q: Is this as good as professional tools?
A: Good quality for most use cases. For maximum quality with faster processing, professional tools like Topaz offer better results but at significant cost.
Q: Why not just use free desktop software like Waifu2x?
A: Desktop software requires installation, GPU driver setup, and technical knowledge. We work instantly in your browser with zero configuration.
Q: What about other free online tools?
A: Most have significant limitations - Canva (1 min limit, requires signup), other sites (watermarks, resolution limits, file size limits). We're truly unlimited. See full comparison →
Q: Is my data safe?
A: Your videos process entirely on your device. They never leave your computer - we never see or store them. Complete privacy.
Q: Do you collect any data?
A: Anonymous usage stats only (page views, button clicks). No video content, no personal information. The tool is open source on GitHub so you can verify this yourself.
Q: Can I use this for sensitive/private videos?
A: Yes. Videos never leave your device. No one sees them - not even us. Perfect for confidential content.
Q: Is this open source?
A: Yes! Code is available on GitHub. Fully transparent and auditable.
Q: Can I use this commercially?
A: Yes. Output videos are yours to use however you want.
Q: Do I need to credit you?
A: No attribution required.
Q: Can I upscale copyrighted content?
A: Tool works with any video, but you're responsible for having rights to the content you process.
Q: I get "WebGPU not supported" error
A: Update your browser to the latest version. Chrome and Edge have best support.
Q: Browser crashes during processing
A: Video may be too large for your device. Try shorter segments or use paid version.
Q: Processing is extremely slow
A: Close other apps, update GPU drivers, or consider paid version for server processing.
Q: Output quality isn't better
A: Source video may already be high quality, or more advanced models needed (paid version).
Q: I have a problem not listed here
A: Report issues or request features at our feedback page.
Q: Can I suggest a feature?
A: Yes! Submit feature requests at our feedback page. The project is also open-source on GitHub.
