Upscale 1080p videos to 4K resolution for free with AI — no watermark, no software install.
Upscale to 4K Free — No WatermarkLooking for a free way to upscale 1080p video to 4K? Most desktop tools require expensive licenses, and many online tools slap watermarks on the output. We offer a different approach: free credits on sign-up, no watermark on any output, and processing on cloud GPUs so you do not need a powerful computer.
The AI upscaling is the same technology regardless of whether you use free or paid credits. There is no quality reduction for free users. Our SeedVSR model analyzes each frame and generates 4K detail — sharper textures, cleaner edges, and finer patterns — producing output that looks noticeably better than what your display's built-in upscaler can achieve. The free credits are enough to test several short clips, and if you need more, credit packages start at just a few dollars with no subscription required.
Upload a 15-second sample to evaluate the quality before spending credits on a longer video. Free credits are enough for several short tests.
The AI model and processing pipeline are identical for all users. Free credits produce the exact same output quality as paid credits.
Unlike many competitors, we never add watermarks — not even on free-tier outputs. Your upscaled video is clean and ready to use.
