Free AI Video Upscaler Online
Pixwit's AI video upscaler reconstructs detail instead of stretching pixels. It reads motion, texture, and compression frame by frame, then rebuilds a cleaner picture at up to 4× while keeping movement natural. Low-resolution phone clips, noisy night footage, and heavily compressed social exports are the usual starting point.
Use it when the story is already in the file and quality is the only problem. Choose a general-purpose path for camera video, a denoise path for grain, an animation path for CGI, or a generative path for text-to-video output. You pay for the seconds you process, and the form on this page is the product — not a teaser that sends you elsewhere.
Treat enhancement as a mastering step, not a reshoot. If the framing, performance, and edit are already right, restoring resolution is cheaper than capturing again. If you still need extra seconds of action, continue the clip first, then return here to polish the picture. The workflow stays editorial: keep what you have, then publish.
How to Upscale a Video with AI
Four steps take you from upload to download on this page. You do not need a desktop suite or a second workspace.
Upload or try the sample
Drop an MP4, MOV, or WebM file up to 100MB, or load the built-in sample to explore settings instantly. The demo clip does not require a second upload.
Pick an enhancement model
Read each description in the picker. Proteus fits most real-world video; Nyx targets noise; Gaia suits animation and CGI; Starlight helps AI-generated footage.
Set scale and optional controls
Choose 1×–4×. Open advanced settings only for custom frame rate, stronger denoise, compression cleanup, or H.264 export. Otherwise the model uses automatic defaults.
Upscale and download
Sign in, confirm the credit estimate, and run enhancement. Preview the result on the right and download the finished MP4 when processing completes.
Why enhance video here
Up to 4× resolution
Scale both sides together so 480p or 720p sources can become 1080p or 4K-ready deliverables without a desktop suite.
Multiple enhancement profiles
Eighteen models cover general footage, denoise and sharpen, CGI and animation, and generative AI video. Each description sits in the picker.
Per-second transparent pricing
Credits follow output resolution and duration. Gaia 2 is billed at half rate; a 60 FPS target uses twice the per-second rate.
Optional frame interpolation
Set a target between 16 and 60 FPS when you want smoother motion. Leave it off to keep the original frame rate.
Fine-grained advanced controls
Override compression cleanup, noise, halo, grain, and detail recovery only when needed. Balanced defaults stay on otherwise.
Secure processing
Uploads are used only for your job. Sample clips stream from our CDN so the demo does not fill local storage.
Choosing the right enhancement model
Match the model to the source, not to a brand name. Proteus is the balanced default. Artemis and Nyx clean grain. Gaia holds edges on rendered frames. Starlight refines generative clips. You can switch profiles and re-run the same file.
Proteus
Default for camera, drone, and screen-captured video when you want a balanced enhance.
Artemis HQ / MQ / LQ
Denoise and sharpen presets when the clip is soft, compressed, or slightly grainy.
Nyx family
Deeper denoising for low light, high ISO, or archival sources that need stronger cleanup.
Gaia HQ / CG / Gaia 2
Clean edges on CGI, motion graphics, and flat-color animation. Gaia 2 runs at 2× with a lower credit rate.
Starlight
Refine diffusion-based and other AI-generated video with precise, sharp, or faster generative paths.
When enhancement helps — and when it does not
An AI video upscaler helps when the picture is soft, blocky, or small, and the content is already correct. It will not invent a missing actor, fix a bad crop, or replace a shot you dislike. If the problem is duration, extend the clip. If the problem is a new scene, generate again. If the problem is resolution and noise, stay on this page.
Simple stretching enlarges pixels; this tool reconstructs texture with motion-aware models. That is why the right profile still matters: a noisy night clip wants Nyx, a 3D render wants Gaia, and a generative take often wants Starlight. Pick the closest match, run a short segment first, then commit the full file.
Popular use cases
Social and UGC clips
Upscale vertical phone video for TikTok, Reels, and Shorts so platform recompression does not leave obvious blocks.
Marketing and product demos
Sharpen screen recordings and webinars so UI text and packaging stay legible at full HD.
Archive and family media
Recover detail in old DV tapes, VHS digitizations, and heavily compressed exports before you share them.
Animation and motion design
Scale motion graphics and 3D renders with models tuned for flat regions and crisp edges.
AI-generated video polish
Use Starlight profiles to stabilize textures and upscale clips from text-to-video tools.
Pre-edit mastering
Prepare a cleaner master before color grading or cutting in Premiere, DaVinci, or Final Cut.
Tools that pair with enhancement
Enhancement is one step. Generate or continue the clip first when the cut still needs new frames, then return here to restore resolution before you publish.
- AI text and image to videoCreate the source clip when you still need a new scene, then enhance it here.
- Video extendAdd the next few seconds when duration is the problem, then upscale the result.
- Long videoPlan a multi-shot narrative when you need more than a single enhanced take.
