Frequently Asked Questions
Q: Is it safe to use RunConvert on public Wi-Fi?
A: We use HTTPS encryption, so your files are secure—even if you're sipping a latte at the airport café.
Q: Can I convert a video to black and white?
A: Not at the moment. We’re focused on format conversion, not visual effects—yet.
Q: What if the video plays fine on my phone but not after conversion?
A: Could be a codec issue—try switching to MP4 H.264 for max compatibility.
Q: Can I convert video to work on my smart TV?
A: Sure! Most smart TVs love MP4. Just avoid ultra-high resolutions if your TV's on the older side.
Q: Can I convert 60fps videos?
A: Sure thing. We preserve the frame rate unless you choose to change it manually.
Q: Can I convert slow-motion videos?
A: Yes, but note: some slow-motion effects are software-based. Converting may flatten them into normal speed.
Q: What format works best for Windows Media Player?
A: WMV is the classic, but MP4 is usually a better modern option that still plays nice with Windows.
Q: Can I change the video resolution when converting?
A: Yes, you can downscale or upscale during conversion—great if you’re saving space or prepping for a bigger screen.
Q: Do I need an account to use RunConvert?
