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 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 or custom resolutions. 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 to process videos directly in your browser using your device's GPU. 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 113+, Edge 113+, Opera 99+, Safari 18+. Chrome recommended for best performance.
Q: Does it work on mobile?
A: Yes, but slower than desktop. Best results on desktop/laptop with dedicated GPU.
Q: Do I need an account?
A: No account needed. Just visit the site and start upscaling. Unlike Canva which requires signup, you can start immediately.
Q: What video formats are supported?
A: MP4 format only for the free version.
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: 2-5 minutes per minute of source video. A 10-minute video takes 20-50 minutes.
Q: Why is it slow?
A: Processing happens on your device, not our servers. Trade-off: completely free but slower. For faster processing, see our paid version.
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 20-50x 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 paid version?
A: If you need results quickly, process videos regularly, or need maximum quality. Learn more →
Q: Can I try both?
A: Yes! Try free first, upgrade to paid when you need speed.
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?

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).
