# HD Video Converter > To convert video to HD, upload it to an AI HD video converter and choose 1080p. Kenerate's AI Video Upscaler increases video resolution from 480p or 720p to 1080p — or 720p, 2K or 4K — rebuilding detail instead of stretching pixels, for MP4, MOV or WebM clips up to 5 minutes.

The smallest HD file. - 1080p · Full HD (Popular) (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 1920 × 1080, shape kept. The standard HD target. - 2K · QHD (Sharp) (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 2560 × 1440, shape kept. Beyond HD for monitors. - 4K · UHD (Max) (AI Video Upscaler): Video up to 5 min / ~100 MB → Pixels of 3840 × 2160, shape kept. Ultra HD screens. ## Steps 1. Upload the clip — MP4, MOV or WebM up to 5 minutes and about 100 MB. 2. Leave 1080p selected — It is the default. Pick 720p for the fastest HD, or 2K and 4K for more. 3. Start the conversion — A short clip takes a few minutes. 4. Download the HD MP4 — Same length and frame rate, original aspect ratio, no watermark. ## In depth ### What 'HD' means 720p (1280 × 720) is the entry level of HD [1]; 1080p (1920 × 1080) is Full HD, with 2.25 times as many pixels [2]. The 'p' stands for progressive scan — every line of every frame is drawn each time. ### Converter vs upscaler File converters change the container or codec, such as AVI to MP4, and leave the resolution alone. Resolution converters resize; a basic resize interpolates new pixels from their neighbours and looks soft. An AI upscaler is a resolution converter that also rebuilds detail [3]. ### Why 1080p is the default 1080p is the size most phones, laptops and social apps display, so it is where an upscale makes the most visible difference for the least processing time. Go to 2K or 4K only when the screen is bigger.

A: For real HD, use a converter that upscales with AI rather than one that only re-wraps or resizes the file. Kenerate's AI Video Upscaler converts clips to 1080p by default — or 720p, 2K or 4K — rebuilds detail across frames and removes compression blocks, with no watermark. Q: How do I upscale a video to 1080p? A: Upload the video to Kenerate's AI Video Upscaler, keep the default 1080p setting and start. A short clip takes a few minutes; then compare the before and after and download the MP4. The aspect ratio, length and frame rate stay the same as your upload. Q: Can I convert 720p to 1080p without losing quality? A: Yes. An AI upscale from 720p to 1080p adds pixels and sharpens detail rather than softening it. Avoid extra re-encodes along the way: upload the original 720p file once, convert it once, and download the 1080p result. Text, faces and edges come out crisper, and the length and frame rate stay exactly as they were. Q: How do I increase video resolution? A: Increase video resolution by upscaling: a video resolution converter adds pixels to every frame. A plain resize makes the picture bigger but softer, while an AI upscaler predicts the missing detail, so text, faces and edges stay crisp at the new size. Q: Does converting to HD change the file format? A: The output is always an MP4. You can upload MP4, MOV or WebM, so a MOV from an iPhone or a WebM screen recording comes back as an HD MP4 that plays almost everywhere, with the same length and frame rate. Q: Will my vertical video be cropped to 16:9? A: No. Sizes are a pixel budget, not a fixed frame: a 9:16 clip at 1080p comes back at about 1080 × 1920, and a square clip stays square. Nothing is cropped, letterboxed or trimmed during the conversion, so the video is ready for vertical apps as soon as you download it. Q: Is the HD video converter free? A: New accounts get starter credits to try it on their own clips. After that you pay per second of clip with credits, with no subscription and no plan required. If a conversion fails, its credits are refunded automatically, and finished HD videos never carry a watermark. ## Related pages - AI video upscaler: https://kenerateai.com/ai-video-upscaler - Upscale video to 4K: https://kenerateai.com/upscale-video-to-4k - Improve video quality: https://kenerateai.com/improve-video-quality - VHS restoration: https://kenerateai.com/vhs-restoration - Fix TikTok video quality: https://kenerateai.com/fix-tiktok-video-quality ## Sources - Kenerate AI Video Upscaler (tool): https://kenerateai.com/app/tool/video-upscale - 720p — Wikipedia: https://en.wikipedia.org/wiki/720p - 1080p — Wikipedia: https://en.wikipedia.org/wiki/1080p - Video super-resolution — Wikipedia: https://en.wikipedia.org/wiki/Video_super-resolution
